CHAPTER I
CASE OVERVIEW
INTRODUCTION
The group choose this title because the patient’s
condition really bothersome. It tickled the group’s minds of
how they will integrate the learned knowledge in connecting the
series of events that lead to the complication the patient is
facing now. The patient had several diagnoses and received
numerous treatment regimens that needs higher thinking order
skills to rationalize such medical intervention. As first
timers at medical intensive care unit, the group did the best
to dig out what was learned from previous lessons and applied
such learnings in rendering wholistic quality paulinian care to
the patient.
Medical Intensive Care Units (MICUs) are designed to meet
the special needs of acutely and critically ill patients.
Patients commonly treated in the MICU include those with
respiratory disease, myocardial ischemia or infarction, or
acute neurologic impairment.
Patient L.L.U. 60 years old, female and a Filipino citizen
residing in A. Mansueto Street, Bogo City, Cebu has experienced
difficulty in breathing, vomiting and loss of consciousness
during the course of her hemodialysis last February 9,2012. Her
signs and symptoms persisted for several hours and was
therefore admitted to PSH- CHI, Medical Intensive Care Unit
last February 10, 2012 for further management. Her family
history showed no bleeding disorders and renal diseases. Mrs.
L.L.U’s diet is usually high in sodium, sugar and fat. She is
also having a sedentary lifestyle. Precipitating and
predisposing factors identified were diabetes mellitus type 2
and hypertension during nursing health history.
The patient was diagnosed of having cardiopulmonary
arrest, end-stage renal disease secondary to DM type 2,
hypertensive emergency(February 11, 2012), healthcare related
1
pneumonia and aspiration pneumonia, diabetes mellitus type 2,
catheter related bacteremia and ventilator acquired pneumonia.
The group decided to choose the patient’s case because
she was under the care and service of both group rotations in
Cebu. Her diagnoses provided the group more opportunity of
learning and of delivering quality ad critical Paulinian care.
The span of time of caring for the patient was of great help as
well in appreciating the disease condition and the nursing
responsibilities asked of the primary nurse. The group has also
realized that among all the patients, she is the one who is the
most physiologically unstable, requiring advanced and
sophisticated judgment. The patient is as well most at risk in
developing serious complications requiring thorough
assessments. Lastly, she was required of intensive and
complicated nursing support related to the use of intravenous
(IV) polypharmacy and advanced biotechnology (e.g. mechanical
ventilation).

SCOPE
This clinical paper contains information related to the care and
condition of the patient. This paper also includes the review of
systems, laboratory results with their corresponding interpretations,
background of the normal anatomy and physiology of the affected part
of the system affected, the pathophysiology of the disease, and the
different surgical, medical, pharmacologic and nursing managements
rendered to the patient and from the moment the patient is under the
group’s care in the Medical Intensive Care Unit of PSH-CHI. The data
gathered depends on the cooperation of the patient, as well as the
length of time they were able to interact with the patient and her
family members.
The group had three weeks exposure in Perpetual Succour Hospital
per rotation, which includes more or less 15 days of clinical duty in
the Operating Room and Medical Intensive Care Unit. The patient was
under the care of ICU group in their 2pm-10pm shift. The OR group was
able to handle the patient for 4 days in their prior rotation and the
patient’s permanent catheter insertion last March 1,2012.
LIMITATIONS
In the process of making this clinical paper, the group
encountered some limitations which are the following:
1. Difficulty in communicating with patient during the first week
(Feb. 20-24) since the patient’s speech was incomprehensible.
2. Achieving consistency of data was difficult since the
patient’s daughter and niece weren’t always there and there
caretaker knew very little about the patient’s personal
information.

Interpretation:
In the patient’s family history, it is presented that Diabetes
Mellitus and Hypertension runs in the family. The genetic capability of
these two diseases made the patient at risk of acquiring these
progressive diseases. Her grandparents have hypertension and one among
them has both diabetes mellitus and hypertension. In the generation of
her parents, one or both of the diseases have been acquired by them. The
individuals which are part of the first two generation died brought about
by their disease condition. In the third generation which involved the
patient, she has diabetes mellitus that lead to nephrosclerosis with End
stage renal failure and Hypertensive Neuropathy as well. Patient’s
current condition may be hereditary and gene encrypted which further more

Routine Laboratory Results
I. Hematologic studies (I)
DEFINITION:A complete blood count (CBC) is a series of tests used to evaluate
the composition and concentration of the cellular components of blood. It consists of a series of tests that determine the number, variety, percentage, concentrations and quality of blood cells.
RATIONALE:The CBC provides valuable information about the blood and to some
extent the bone marrow, which is the blood-forming tissue. The CBC is used for the following purposes as a preoperative test to ensure both adequate oxygen carrying capacity and hemostasis, to identify persons who may have an infection, to diagnose anemia, to identify acute and chronic illness, bleeding tendencies, and white blood cell disorders such as leukemia, to monitor treatment for anemia and other blood diseases and to determine the effects of chemotherapy and radiation therapy on blood cell production.

INTERPRETATION:
Hematologic studies shows that patient is having severe infection because WBC results are increased, RBC results (hemoglobin, platelet, hematocrit) are decreased which indicates decrease O2 carrying capacity and risk for bleeding.
29
II. Hematologic studies (II)
DEFINITION: These are series of tests that measure the clotting mechanisms of the body and identify the type & extent of suspected coagulation studies.
RATIONALE: Clotting time and bleeding time are assessed in the case of our patient because upon assessment of surgical incision, presence of palpable hematoma or blood clot was noted and needs to be lyzed & excreted out of the body. These tests are important to determine if anti-platelets and anti-coagulants can be safely given to our patient or not, especially in patients with hemophilic cases that bleed easily, Anti-coagulants, Thrombolytics, anti-platelet medications are strictly contraindicated.

Table 2.2 Prothrombin Time Results
INTERPRETATION:
Hematologic studies (II) show that patient’s results are normal. This indicates that patient’s body is using up its clotting factors so quickly that the blood can bleed and clot at its normal span of time.
III. Blood Chemistry
DEFINITION: Blood chemistry testing is defined simply as identifying the numerous chemical substances found in the blood. The serum chemistry profile is one of the most important initial tests that is commonly performed. These measurements aid in assessing the function of various organs and body systems. The analysis of these substances will provide clues to the functioning of the major body systems.
RATIONALE: Most nurses are concerned with the fact that many blood chemistry tests are performed on the serum derived from whole blood. Serum, of course, is the liquid remaining after whole blood has clotted in the sample tube. Some blood chemistry tests are performed on other parts of blood as well.

INTERPRETATION:
Blood chemistry results shows that sodium level is decreased which indicates dilutional hyponatremia since patient is experiencing generalized edema. Increased SGPT and creatinine also indicates increased nitrogenous waste products circulating in the serum. Decreased calcium in the serum indicates hypocalcemia which was supported in the CT scan result that calcium is deposited in the gallbladder and in the left kidney.
IV. Capillary Blood Sugar
DEFINITION:
Blood glucose monitoring is a way of testing the concentration of glucose in the blood (glycemia). Particularly important in the care of diabetes mellitus, a blood glucose test is performed by piercing the skin (typically, on the finger) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
31
RATIONALE:
This is routinely done to the patient to monitor her blood glucose level since the patient had a diabetes mellitus type 2 which reveals individual patterns of blood glucose changes, and helps in the planning of meals, activities, and at what time of day to take medications. Also, testing allows for quick response to high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia). This might include diet adjustments, exercise, and insulin (as instructed by the health care provider).

Interpretation:
The result shows that patient had fluctuating blood glucose level since February 10 until March 5, 2012. Almost all results from the first day were above 100mg/dl. There were no result showing decrease in blood glucose level of the patient.
V. Urinalysis (urinary catheter)
DEFINITION: Urinalysis is a test that determines the content of the urine. Urinalysis can be used to detect some types of disease, particularly in the case of metabolic disorders and kidney disease. It can also be used to uncover evidence of drug abuse.
RATIONALE: This was ordered to the patient to identify if the patient is having a urinary tract or kidney infection since patient is experiencing END Stage Renal Disease. This also used to evaluate patient’s causes of kidney failure, to screen for progression of her chronic conditions such as diabetes mellitus and high blood pressure (hypertension)

The result shows positive for glucose which indicates that the filtered load of glucose exceeds the maximal tubular reabsorvative capacity for glucose, positive for blood which indicates presence of large number of RBC’s and WBC’s in the urine sediment which establishes the diagnosis of hematuria and presence of rare amount of mucus threads, amorphous materials and bacteria which indicates infection.
VI. Fecalysis
DEFINITION:
Fecalysis is also known as stool analysis. It refers to a series of laboratory tests done on fecal samples to analyze the condition of a person's digestive tract in general. Among other things, a fecalysis is performed to check for the presence of any reducing substances such as white blood cells (WBCs), sugars, or bile and signs of poor absorption as well as screen for colon cancer.
RATIONALE: This is done to the patient for diagnostic purposes such as to examine the general condition of the digestive tract of the patient if there are any changes on the levels of any substances such as RBC and WBC which may be signs of infection and if the patient is having signs of poor absorption.

S PECIFIC LABORATORY RESULTS
I. Arterial Blood Gases
DEFINITION:Arterial blood gases (ABGs) are diagnostic tests performed on
blood taken from an artery which contains oxygen and carbon dioxide.
RATIONALE:
Arterial Blood Gases or ABG’s are done to evaluate oxygenation and acid-base-balance. Numerous factors can be evaluated to determine whether tissue oxygenation is adequate and the excretion of waste products (CO2- carbon dioxide) is occurring properly from the lungs.

INTERPRETATION:
Patient’s ABG result shows that there is a decrease in the PO2 ,HCO3
and PaO2 thereby indicates that the patient’s lungs are unable to release the rising systemic carbon dioxide. Causing the body’s acid-base balance to become unstable.
II. Cardiac Troponin I
DEFINITION:
Troponin tests are primarily ordered to evaluate people who have chest pain to see if they have had a heart attack or other damage to their heart. However, troponins are the preferred tests for a suspected heart attack because they are more specific for heart injury than other tests (which may become positive in skeletal muscle injury) and remain elevated for a longer period of time.
RATIONALE:
The troponin test is used to help diagnose a heart attack, to detect and evaluate mild to severe heart injury, and to distinguish chest pain that may be due to other causes. In those who experience heart-related chest pain, discomfort, or other symptoms and do not seek medical attention for a day or more, the troponin test will still be positive if the symptoms are due to heart damage.

III. Blood Culture
DEFINITION:
A blood culture is a test to find an infection in the blood. The blood does not normally have any bacteria or fungi in it. A blood culture can show what bacteria or fungi are in the blood.
35
RATIONALE:
A blood culture is done to find if the patient is experiencing bacterial infection that has spread into the different systems of the body since the patient is at risk for developing infection due to her intrajugular Catheter and endotracheal tube, venous cutdown and AV Fistula. A culture can also show what type of bacteria is causing the infection such as fungal infection. This finds the best antibiotics for the patient to kill the bacteria or a fungus which is called sensitivity testing and as well as finds the cause of an unexplained fever or shock or a person becoming extremely ill.

Table 2.8 Blood Culture Results
INTERPRETATION:
Blood culture shows that patient is positive for Candida Tropicalis and Burkholderia Cepacia both on IJ Cath and ET Tube Tip. Once B. cepacia enters the body, there are three possible effects and it is not possible to predict which will happen. Sometimes B. cepacia colonizes in the lungs, causes no symptoms, and has no long term effect. Other times B. cepacia colonizes in the lungs and causes damaging lung infections and inflammation that lead to a slow deterioration of lung function. Candida tropicalis is a species of fungus that belongs to the Candida family. Like the more common Candida albicans, it is a yeast-type fungus that proliferates in the skin and digestive tract and is a normal fungus that grows in most animals and humans. However, Candida tropicalis often proliferates to the point it can cause septicemia (a type of poisoning or infection) in the body, especially in those with diabetes, lymphoma and leukemia.
IV. Urine Culture
DEFINITION:
A urine culture is a test to find and identify germs (usually bacteria) that may be causing a urinary tract infection (UTI).
RATIONALE:
36
This test was done to the patient to know if the patient is experiencing urinary tract infection and to know the growth rate of the microorganism present in the urine of the patient.
DATE RESULTFebruary 26, 2012 Gram + Cells: no microorganisms

INTERPRETATION:
The results of urine culture shows negative for microorganism growth after 24 and 48 hours of incubation.
V. Antimicrobial Susceptibility Testing
DEFINITION:
AST is a laboratory method for determining the susceptibility of organisms to therapy with antibiotics.
RATIONALE:
This was done to the patient to determine what kind of antibiotics is susceptible or resistant to the bacteria or fungi causing the infection in the patient. This helps the patient identify the best antibiotic therapy for the patient’s condition.

DIAGNOSTIC RESULTS
I. Medical Imaging Center (CT scan section)
DEFINITION:
Computed Tomography (CT) is a powerful nondestructive evaluation (NDE) technique for producing 2-D and 3-D cross-sectional images of an object from flat X-ray images.
RATIONALE:
CT is used for spine and head imaging, gastrointestinal imaging, vascular imaging (e.g., detection of blood clots), cancer staging and radiotherapy treatment planning, screening for cancers and heart disease, rapid imaging of trauma, imaging of musculoskeletal disorders, detection of signs of infectious disease, and guidance of
38
certain interventional procedures (e.g., biopsies). CT is the most commonly performed procedure for imaging the chest. CT is also used to perform noninvasive angiographic imaging to assess the large blood vessels.

II. Electroencephalogram
DEFINITION:
An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Certain conditions, such as seizures, can be seen by the changes in the normal pattern of the brain's electrical activity.
RATIONALE:
An electroencephalogram (EEG) was done to the patient to check the patient’s electrical activity of the brain and to diagnose epilepsy and see what types of seizures are occurring in her. EEG is useful and important test in confirming a diagnosis of epilepsy. This checks the patient’s problems with loss of consciousness or dementia and help find out a patient's chance of recovery after a change in consciousness.
Date: February 13, 2012
Clinical History: Patient had history of cardiopulmonary arrest for approximately 12-15 minutes post-resuscitation she was noted to have referential gaze and decrease sensorium
Technical Reading: This is a 16 electrode EEG recording done in wakefulness and drowsiness. No sleep recording was performed. The background activity in wakefulness predominantly consists of low amplitude. Theta waves 5-7 Hz. There is good reactivity to manual eye closure and opening. Photic stimulation was remarkable. Hyperventilation was not performed. No epileptiform discharges and clinical events were noted during the recording.
Conclusion: This is an abnormal EEG recording due to the presence generalized slowing of background activity in wakefulness. This may be found in cases like hypoxic encephalopathy. No epileptiform activity was noted during the recording.
III. Electrocardiogram
DEFINITION:
41
An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG translates the heart's electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves.
RATIONALE:
An electrocardiogram (EKG or ECG) is done to the patient to check her heart's electrical activity and find the cause of her unexplained chest pain, which could be caused by a heart attack, inflammation of the sac surrounding the heart (pericarditis), or angina. This also finds the cause of symptoms of the patient’s heart disease, such as shortness of breath,dizziness, fainting, or rapid, irregular heartbeats (palpitations) and to find out if the walls of the heart chambers are too thick (hypertrophied). This checks the health of the heart because high blood pressure, high cholesterol, diabetes, or a relative who had early heart disease are present to the patient.

IV. Chest X-ray
DEFINITION: A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. X rays are a form of radiation that can penetrate the body and produce an image on an x-ray film. Another name for x ray is radiograph.
RATIONALE: Chest X-RAY was ordered to my patient for diagnostic purposes to
detect if there any abnormalities in her lungs since she commonly was experiencing dyspnea as well detect abnormalities in her heart, aorta, and the bnes of the thoracic area. This was also done to the patient to compare previous studies and check for the placement of her endotracheal tube since she have ET tube upon admission.

ANATOMY AND PHYSIOLOGY
ENDOCRINE SYSTEM
Homeostasis depends on the precise regulation of the organs and organ systems of the body. The nervous ad endocrine systems are the two major systems responsible for that regulation. Together they regulate ad coordinate the activity of nearly all other body structures. When these systems fail to function can result in diseases such as diabetes mellitus or Addison’s disease.
The regulatory functions of the nervous and endocrine systems are similar in some respects, but they differ in other important ways. The nervous system controls the activity of tissues by sending action potentials along axons, which release chemical signals at their ends, near the cells they control. The endocrine system release chemical signals into the circulatory system, which carries them to all parts of the body. The cells that can detect those chemical signals produce responses.
The nervous system usually acts more quickly and has short-term effects, whereas the endocrine system usually responds more slowly and has longer-lasting effects. In general, each nervous stimulus controls a specific tissue or organ, whereas each endocrine stimulus controls several tissues or organs.
Functions of endocrine system
The main regulatory functions of the endocrine system include:
1. Water balance. The endocrine system regulates water balance by controlling the solute concentration of the blood.
2. Uterine concentration and milk release. Regulates uterine contractions during delivery of the newborn and stimulates milk release from the breasts in lactating females.
45
Fig.A.1 ENDOCRINE SYSTEM
3. Growth, metabolism, and tissue maturation. Regulates the growth of many tissues, such as bone and muscle, and the rate of metabolism of many tissues, which helps maintain a normal body temperature and normal mental functions. Maturation of tissues, which results in the development of adult features and adult behavior, are also influenced by the endocrine system.
4. Ion regulation. Regulates Na+, K+, and Ca2+ concentrations in the blood.
5. Heart rate and blood pressure regulation. The endocrine system helps regulate the heart rate and blood pressure and helps prepare the body for physical activity.
6. Blood glucose control. The endocrine system regulates blood glucose levels and other nutrients level in the blood.
7. Immune system regulation. Helps control the production and functions of immune cells.
8. Reproductive functions control. Controls the development and the functions of the reproductive system in males and females.
Endocrine glands: Endocrine organs, called glands, secrete hormones into the bloodstream. Hormones affect the activity of target sites that are often located far from the site of release. Exocrine organs direct the function of their target sites by releasing their active.
Human endocrine system: The major endocrine organs include the hypothalamus and the hypophysis, or pituitary gland. Other endocrine glands within the body include: thyroid, parathyroids, adrenals, pancreas, ovaries, and testes.
The hypothalamus: The hypothalamus is located in the forebrain, directly above the pituitary gland. The hypothalamus receives input from other parts of the brain and from peripheral nerves. This input affects neurosecretory cells within the hypothalamus.
The pituitary gland: The anterior pituitary synthesizes its own hormones. Capillaries within the anterior pituitary receive signals from the hypothalamus that tell the anterior pituitary whether or not to release certain hormones.
The thyroid gland: The thyroid gland is a bilobed structure found at the trachea. It synthesizes and secretes three hormones:
1. thyroxine (T4),2. triiodothyronine (T3), and3. calcitonin.
The parathyroids are four small glands embedded in the thyroid. They produce and secrete parathyroid hormone (PTH).
The adrenal gland: The adrenal glands are located on top of the kidneys. Each gland is subdivided into an outer adrenal cortex and an inner adrenal medulla.
The pancreas: The pancreas is both an endocrine organ and an exocrine organ. The exocrine portion of the pancreas secretes digestive enzymes into the pancreatic duct. The endocrine portion of the pancreas secretes hormones, including insulin and glucagon.
The ovaries: The ovaries produce and secrete steroid hormones known as estrogens and progesterone.
TYPES OF HORMONES
In order to regulate the myriad functions required for normal bodily function, the glands and organs that comprise the endocrine system create many types of hormones, each with a specific function. Included in the
46
different types of hormones your endocrine system produces are the following:
Vasopressin -- Created by the hypothalamus, vasopressin prompts the pituitary gland to release a hormone that helps maintain blood pressure and water and electrolyte balance.
Growth Hormone -- Growth hormone, or GH, is one of the types of hormones produced by the pituitary gland (one of the most important glands in the endocrine system); GH stimulates growth during childhood and also stimulates cell reproduction, which helps adults maintain muscle and bone mass.
Calcitonin -- Calcitonin, produced by the thyroid gland, aids in bone construction.
Insulin -- Insulin regulates glucose, or sugar intake, by helping it move from the blood into cells. Insulin is a hormone produced by the pancreas which is central regulating carbohydrate and fat metabolism in the body. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle. Insulin stops the use of fat as an energy source by inhibiting the release of glucagon. With the exception of the metabolic disorder diabetes mellitus and Metabolic syndrome, insulin is provided within the body in a constant proportion to remove excess glucose from the blood, which otherwise would be toxic. When blood glucose levels fall below a certain level, the body begins to use stored sugar as an energy source through glycogenolysis, which breaks down the glycogen stored in the liver and muscles into glucose, which can then be utilized as an energy source. As its level is a central metabolic control mechanism, its status is also used as a control signal to other body systems. In addition, it has several other anabolic effects throughout the body.
When control of insulin levels fails, diabetes mellitus will result. As a consequence, insulin is used medically to treat some forms of diabetes mellitus. Patients with type 1 diabetes depend on external insulin for their survival because the hormone is no longer produced internally. Patients with type 2 diabetes are often insulin resistant and, because of such resistance, may suffer from a "relative" insulin deficiency. Some patients with type 2 diabetes may eventually require insulin if other medications fail to control blood glucose levels adequately. Over 40% of those with Type 2 diabetes require insulin as part of their diabetes management plan. Insulin also influences other body functions, such as vascular compliance and cognition. Once insulin enters the human brain, it enhances learning and memory and benefits verbal memory in particular. Enhancing brain insulin signaling by means of intranasal insulin administration also enhances the acute thermoregulatory and glucoregulatory response to food intake, suggesting that central nervous insulin contributes to the control of whole-body energy homeostasis in humans. Human insulin is a peptide hormone composed of 51 amino acids and has a molecular weight of 5808 Da. It is produced in the islets of Langerhans in the pancreas.
Adrenaline -- Produced within the adrenal glands (small glands located at the top of each kidney), adrenaline works with noradrenaline to produce the "fight or flight" response by increasing the supply of oxygen to the brain and muscles, dilating the pupils, and suppressing bodily functions not useful in an emergency situation (such as digestion).
Noradrenaline -- Noradrenaline works with adrenaline to help the endocrine system produce the "flight or flight" response; in an emergency situation, it boosts the oxygen supply to the brain and the supply of glucose to the muscles.
CARDIOVASCULAR SYSTEM
47
The heart is a muscular organ that is essential for life because it pumps blood through the body. Fluids flow through the entire body only if they are forced to do so. The force is commonly produced by a pump, which increases the pressure of the liquid at the pump above the pressure in the pipe. Thus, the liquid flows from the pump through the pipe from an area of higher pressure to an area of lower pressure. If the pressure produced by the pump decreases, flow the liquid through the pipe decreases.
Like a pump that forces water to flow through a pipe, the heart contracts forcefully to pump blood through the blood vessels of the body. The heart of a healthy adult, at
Functions of the heart
1. Generating blood pressure. Contractions of the heart generate blood pressure, which is required for blood flow through the blood vessels.
2. Routing blood. The heart separates the pulmonary and systemic circulations, which ensures the flow of oxygenated blood to tissues.
3. Ensuring one-way blood flow. The valves of the heart ensure rest, pumps approximately 5 liters of blood per minute. For most people, the heart continues to pump at approximately that rate for more than 75 years; and, during short periods of vigorous exercise, the amount of blood pumped per minute increases several fold. If the heart loses its pumping ability foe even a few minutes, however, blood flow through the blood vessels stops and the life of the individual is in danger.The heart is actually two pumps in one. The right side of the heart pumps blood to the lungs and back to the left side of the heart through vessels of the pulmonary circulation. The left side of the heart pumps blood to all other tissues of the body ad back to the right side of the heart through vessels of the systemic circulation a one-way flow of blood through the heart and blood vessels.
4. Regulating blood supply. Changes in the rate and force of heart contraction match blood flow to the changing metabolic needs of the tissues during rest, exercise, and changes in body position.
The Circulatory System: The circulatory system delivers oxygen and nutrients to tissues and removes carbon dioxide and waste from tissues.
48
Fig. A. 2. CARDIOVASCULAR SYSTEM
Blood circulation: Pulmonary Circuit - circulation between lung and heart releases carbon dioxide.
Systemic Circuit - circulation between the heart and body delivers oxygen and nutrients and also picks up waste.
The Heart: Anatomy and Conduction: The main pump in the cardiovascular system which generates the pressure required to move blood through the system.
SA node: The heart has a unique, automatic electrical conducting system. The central nervous system (CNS) modulates the rate of contraction of the heart, but the heart can generate and maintain its own rhythm independent of the CNS. Sinoatrial node contains pacemaker cells, which create action potentials at a frequency that results in a normal heart rate of 70-80 beats/minute.
Electrocardiography: The electrocardiogram detects the electrical activity of each heartbeat as it develops over time. The P wave represents the depolarization as it spreads over the atria. The QRS complex corresponds to the current that spreads over the ventricles. The T wave represents the repolarization of the ventricles, during which time they become ready for the next contraction.
Oxygen Delivery to the TissuesBlood pressure is generated by the heart and facilitates delivery of nutrients to the body.
Capillaries are the smallest blood vessels, where exchange takes place. Passive diffusion lets oxygen/ nutrients out of the blood into the tissue, and lets carbon dioxide/ waste out of the tissue into the blood. Hydrostatic pressure is caused by the blood pressure generated by the heart beating. Na+ and other electrolytes cause osmotic pressure.
Blood & Blood Vessels
Smooth muscle around arterioles modulates blood pressure by changing peripheral resistance. If systemic blood pressure is decreased, neuromodulation of the arterioles causes vasoconstriction, which, in turn, causes an increase in blood pressure.Blood is made up of the following components: plasma contains water and proteins, red blood cells, white blood cells and platelets. Coagulation is an important process in which soluble proteins form an insoluble clot.Oxygen is delivered to the tissues bound to hemoglobin. Hemoglobin is a metalloprotein, made up of 4 globin polypeptide chains with 4 imbedded oxygen-binding heme molecules.
URINARY SYSTEM
49
The urinary system consists of two kidneys, two ureters, the urinary bladder, and the urethra. A large volume of blood flows through the kidneys, which removes substances consumed with food. The urine produced by the kidneys flows through the ureters to the urinary bladder, where it is stored until it is eliminated through the urethra.
The kidneys can suffer extensive damage and still maintain their extremely important role in the maintenance of homeostasis. As long as about one-third of one kidney remains functional, survival is possible. If the functional ability of the kidneys fail completely, however, death will result without special medical treatment.
Functions of the urinary system
1. Excretion Remove waste products, many of which toxic, from the blood. Most waste products are metabolic by –products of cells and substances absorbed from the intestine. The skin, liver, lungs, and intestines eliminate some of these waste products, but they cannot compensate if the kidneys fail to function.
2. Regulation of blood volume and pressure. The kidneys play a major role in controlling the extracellular fluid volume in the body by producing either a large volume of dilute urine or a small volume of concentrated urine. Consequently, blood volume and blood pressure are regulated by the kidneys.
3. Regulation of the concentration of solutes in the blood. The kidneys help regulate the concentration of the major molecules and ions such as glucose, Na+, Cl-, K+, Ca2+, HCO3-, and HPO4 2-.
4. Regulation of red blood cells synthesis. The kidneys secrete a hormone, erythropoietin, which regulates the synthesis of red blood cells in bone, marrow.
5. Vitamin D synthesis. The kidneys play an important role in controlling blood levels of Ca2+ by regulating the synthesis of vitamin D.
Kidneys The kidneys are located in the back of the upper abdomen and are protected by the lower ribs and rib cartilage of the back. The kidneys are involved with a number of bodily functions which include:
The filtering and excretion of unwanted waste products such as urea from the body.
The maintenance of water balance. the regulation of the acid-base balance of body fluids. the production of renin, which is important in the regulation of blood pressure.
50
Fig. A. 3 URINARY SYSTEM
The production of the hormone erythropoieten, which stimulates the production of red blood cells.
Ureters The ureters are two slender tubes that run from the sides of the kidneys to the bladder. Their function is to transport urine from the kidneys to the bladder.
Bladder The bladder is a muscular organ and serves as a reservoir for urine. Located just behind the pubic bone, it can extend well up into the abdominal cavity when full. Near the outlet of the bladder is a small muscle called the internal sphincter, which contract involuntarily to prevent the emptying of the bladder.
Urethra The urethra is a tube that extends from the bladder to the outside world. It is through this tube that urine is eliminated from the body.
HEMATOLOGIC SYSTEM
The structures of the hematologic or hematopoietic system include the blood, blood vessels, and blood-forming organs (bone marrow, spleen, liver, lymph nodes, and thymus gland). The major function of blood is to carry necessary materials (oxygen, nutrients) to cells and to remove carbon dioxide and metabolic waste products. The hematologic system also plays an important role in hormone transport, the inflammatory and immune responses, temperature regulation, fluid-electrolyte balance, and acid-base balance.
Bone Marrow Contained inside all bones, occupies interior of spongy bones and
center of long bones; Primary function is hematopoiesis (the formation of blood cells) Two kinds of bone marrow, red and yellow
Red (functioning) marrow Carries out hematopoiesis; production site of erythroid,
myeloid, and thrombocytic components of blood; one source of lymphocytes and macrophages
Yellow marrow: red marrow that has changed to fat; found in long bones; does not contribute to hematopoiesis
51
Fig. A. 4. HEMATOLOGIC SYSTEM
All blood cells start as stem cells in the bone marrow; these mature into the different, specific types of cells, collectively referred to as formed elements of blood or blood components: erythrocytes, leukocytes, and thrombocytes.

Plasma Liquid part of blood; yellow in color because of pigments Consists of serum (liquid portion of plasma) and fibrinogen Contains plasma proteins such as albumin, serum globulins,
fibrinogen, prothrombin, plasminogen Albumin: largest of plasma proteins, involved in regulation of
intravascular plasma volume and maintenance of osmotic pressure Serum globulins: alpha, beta, gamma
Alpha: role in transport of steroids, lipids, bilirubin Beta: role in transport of iron and copper Gamma: role in immune response, function of antibodies
Fibrinogen, prothrombin, plasminogen (see Coagulation)
Cellular Components Cellular components or formed elements of blood are erythrocytes which are responsible for oxygen transport; leukocytes which play a major role in defense against microorganisms; and thrombocytes which function in hemostasis.
Erythrocytes [Red Blood Cells (RBC)] Bioconcave disc shape, no nucleus, chiefly sacs of hemoglobin RBCs are responsible for oxygen transport via hemoglobin (Hgb)
Two portions: iron carried on heme portion; second portion is protein
Normal blood contains 12-18 g Hgb/100 ml blood; higher (14-18 g) in men than in women (12-14 g)
Production Start in bone marrow as stem cells, released as
reticulocytes (immature cells), mature into erythrocytes Erythropoietin stimulates differentiation; produced by
kidneys and stimulated by hypoxia Iron, vitamin B12, folic acid, pyridoxine (vitamin B6), and
other factors required for erythropoiesis Hemolysis (destruction)
Average life span 120 days Immature RBCs destroyed in either bone marrow or other
reticuloendothelial organs (blood, connective tissue,
52
spleen, liver, lungs, and lymph nodes) Mature cells removed chiefly by liver and spleen Bilirubin: byproduct of Hgb released when RBCs destroyed,
excreted in bile Iron: freed from Hgb during bilirubin formation;
transported to bone marrow via transferrin and reclaimed for new Hgb production
Premature destruction: may be caused by RBC membrane abnormalities, Hgb abnormalities, extrinsic physical factors
Normal age RBCs may be destroyed by gross damage as in trauma or extravascular hemolysis (in spleen, liver, bone marrow)
Leukocytes: granulocytes and mononuclear cells [White Blood Cells (WBC)]: involved in protection from bacteria and other foreign substances
Granulocytes: eosinophils, basophils, and neutrophils Eosinophils: involved in phagocytosis and allergic
reactions Basophils: involved in prevention of clotting in
microcirculation and allergic reactions Eosinophils and basophils are reservoirs of histamine,
serotonin, and heparin Neutrophils: involved in short-term phagocytosis
mature neutrophils: polymorphonuclear leukocytes immature neutrophils: band cells (bacterial infection
usually produces increased numbers of band cells) Mononuclear cells: monocytes and lymphocytes: large nucleated
cells Monocytes: involved in long-term phagocytosis; play a role
in immune response largest leukocyte produced by bone marrow: give rise to histiocytes
(Kupffer cells of liver), macrophages, and other components of reticuloendothelial system
Lymphocytes: immune cells; produce substances against foreign cells; produced primarily in lymph tissue (B cells) and thymus (T cells) (see also Immune Response)
Thrombocytes (Platelets) Fragments of megakaryocytes formed in bone marrow Production regulated by thrombopoietin Essential factor in coagulation via adhesion, aggregation, and
plug formation Release substances involved in coagulation
Systems that initiate clotting Intrinsic system: initiated by contact activation following
endothelial injury ("intrinsic" to vessel itself) Factor XII initiates as contact made between damaged
vessel and plasma protein Factors VIII, IX, and XI activated

vessels ("extrinsic" to vessel) Factor VII activated
Common pathway: activated by either intrinsic or extrinsic pathways
53
Platelet factor 3 (PF3) and calcium react with factors X and V. Prothrombin converted to thrombin via thromboplastin. Thrombin acts on fibrinogen, forming soluble fibrin. Soluble fibrin polymerized by factor XIII to produce a stable,
insoluble fibrin clot. Clot resolution: takes place via fibrinolytic system by plasmin and
proteolytic enzymes; clot dissolves as tissue repairs.
GENITOURINARY SYSTEM
Structures and functions:
Ovaries
Are paired organs that produce secondary oocytes (cells that develop into mature ova, or eggs, following fertilization) and hormones, such as progesterone and estrogens (the female sex hormones), inhibin, and relaxin.
Uterine Tubes
Females have two uterine (fallopian tube) tubes that extend laterally from the uterus and transport the secondary oocytes from the ovaries to the uterus and are normally are the sites where fertilization occurs.
Uterus
The uterus serves as a part of the pathway for sperm deposited in the vagina to reach the uterine tubes. This is the site for the implantation of a fertilized ovum, development of the fetus during pregnancy and labor.
Vagina
The vagina is a tubular canal that extends from the exterior of the body to the uterine cervix. It receives the penis during sexual intercourse and is a passageway for childbirth.
Perineum and Vulva
The perineum is the diamond- shaped area between the thighs and buttocks of both males and females that contains the external genital s and anus.
The term vulva refers to the external genitals of the female. The mons pubis is an elevation of adipose tissue covered by coarse pubic hair, which cushions the public symphysis. From the mons pubis, two longitudinal folds of skin, the labia majora, extend down and back. Medial to the labia majora are two folds of skin called the labia minora. The labia minora do not contain pubic hair or fat and have fe sudoferous (sweat) glands, they
do, hoever contain numerous sebaceous (oil) glands. The clitoris is a small, cylindrical mass of erectile tissue and nerves. It is located at the anterior junction of the labia minora.
Mammary Glands
The mammary glands located in the breasts, are modified sudoferous (sweat) glands that produce milk. The breasts lie over the
54
pectoralis major ad serratus anterior muscles and are attached to them by a layer of connective tssuee. These synthesize, secrete and eject milk for nourishment of the newborn through a series of closely spaced opening of ducts, which we called as nipples, one pigment projection in each breast.
NEUROLOGICAL SYSTEM
FIGURE 3.1 The Nervous System
The nervous system is broken down into two major part: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes all nerves, which carry impulses to and from the brain and spinal cord. These include our sense organs, the eyes, the ears, our sense of taste, smell and touch, as well as our ability to feel pain.
A.)Central Nervous System
Spinal Cord The spinal cord is a long bundle of neural tissue continuous with the
brain that occupies the interior canal of the spinal column and functions as the primary communication link between the brain and the rest of the body. The spinal cord receives signals from the peripheral senses and relays them to the brain.
Ascending and Descending Spinal TractsAscending tracts within the spinal cord carry sensory
information from the body, upwards to the brain, such as touch, skin temperature, pain and joint position.
Descending tracts within the spinal cord carry information from the brain downwards to initiate movement and control body functions.
Spinal NervesNerves called the spinal nerves or nerve roots, branch off the
spinal cord and pass out through a hole in each of the vertebrae called the Foramen. These nerves carry information from the spinal cord to the rest of the body, and from the body back up to the brain.
There are four main groups of spinal nerves, which exit different levels of the spinal cord. These are in descending order down the vertebral column:
Cervical Nerves "C": (nerves in the neck) supply movement and feeling to the arms, neck and upper trunk. Also control breathing.
Thoracic Nerves "T": (nerves in the upper back) supply the trunk and abdomen.
Lumbar Nerves "L" and Sacral Nerves "S" : (nerves in the lower back) supply the legs, the bladder, bowel and sexual organs.
Brain
Brain Stem The brain stem is the part of the brain that connects the cerebrum
and diencephalons with the spinal cord.
Medulla Oblongata
The medulla oblongata is located just above the spinal cord. This part of the brain is responsible for several vital autonomic centers including:
55
Fig. A.5 NERVOUS SYSTEM
The respiratory center, which regulates breathing. The cardiac center that regulates the rate and force of the
heartbeat. The vasomotor center, which regulates the contraction of smooth
muscle in the blood vessel, thus controlling blood pressure.
The medulla also controls other reflex actions including vomiting, sneezing, coughing and swallowing.
Pons
Continuing up the brain stem, one reaches the Pons. The pons lies just above the medulla and act as a link between various parts of the brain. The pons connects the two halves of the cerebellum with the brainstem, as well as the cerebrum with the spinal cord. The pons, likes the medulla oblongata, contain certain reflex actions, such as some of the respiratory responses.
Midbrain
The midbrain extends from the pons to the diecephalon. The midbrain acts as a relay center for certain head and eye reflexes in response to visual stimuli. The midbrain is also a major relay center for auditory information.
Diencephalon
The diencephalons are located between the cerebrum and the mid brain. The diencephalons houses important structures including the thalamus, the hypothalamus and the pineal gland.
Thalamus
The thalamus is responsible for "sorting out" sensory impulses and directing them to a particular area of the brain. Nearly all sensory impulses travel through the thalamus.
Hypothalamus
The hypothalamus is the great controller of body regulation and plays an important role in the connection between mind and body, where it serves as the primary link between the nervous and endocrine systems. The hypothalamus produces hormones that regulate the secretion of specific hormones from the pituitary. The hypothalamus also maintains water balance, appetite, sexual behavior, and some emotions, including fear, pleasure and pain.
Cerebellum
The functions of the cerebellum include the coordination of voluntary muscles, the maintenance of balance when standing, walking and sitting, and the maintenance of muscle tone ensuring that the body can adapt to changes in position quickly.
Cerebrum
56
The largest and most prominent part of the brain, the cerebrum governs higher mental processes including intellect, reason, memory and language skills. The cerebrum can be divided into 3 major functions:
Sensory Functions - the cerebrum receives information from a sense organ; i.e., eyes, ears, taste, smell, feelings, and translates this information into a form that can be understood.
Motor Functions - all voluntary movement and some involuntary movement.
Intellectual Functions - responsible for learning, memory and recall.
Meninges
The meninges are made up of three layers of connective tissue that surround and protect both the brain and spinal cord. The layers include the dura mater, the arachnoid and the pia matter.
Cerebrospinal Fluid
The cerebrospinal fluid is a clear liquid that circulates in and around the brain and spinal cord. Its function is to cushion the brain and spinal cord, carry nutrients to the cells and remove waste products from these tissues.
B.) Peripheral Nervous System
Nerves
Nerves are made up of specialized cells, which act as little wires, transmitting information to and from the central nervous system and brain. Nerves form the network of connections that receive signals (known as sensory input) from the environment and within the body, and transmit the body's responses, or instructions for action, to the muscles, organs, and glands. Nerve cells are located outside the central nervous system or spinal cord.
Neuron Structure
The brain is made of approximately 100 billion nerve Figure 3.2 neuron cells, called neurons.Neurons have the amazing ability to gather and transmit electrochemical signals.
Neurons share the same characteristics and have the same makeup as other cells, but the electrochemical aspect lets them transmit signals over long distances (up to several feet or a few meters) and send messages to each other.Neurons have three basic parts:
Cell body or soma. This main part has all of the necessary components of the cell, such as the nucleus (which contains DNA), endoplasmic reticulum and ribosomes (for building proteins) and mitochondria (for making energy). If the cell body dies, the neuron dies.
57
Fig. A. 6 NEURONS
Axon . This long, cablelike projection of the cell carries the electrochemical message (nerve impulse or action potential) along the length of the cell. Depending upon the type of neuron, axons can be covered with a thin layer of myelin sheath, like an insulated electrical wire. Myelin is made offat and protein, and it helps to speed transmission of a nerve impulse down a long axon. Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord.
Dendrites or nerve endings. These small, branchlike projections of the cell make connections to other cells and allow the neuron to talk with other cells or perceive the environment. Dendrites can be located on one or both ends of a cell.
Basic Types of NeuronsThese fundamental members of the nervous system also vary with respect to their functions.
Sensory neurons carry signals from the outer parts of your body (periphery) into the central nervous system.
Motor neurons (motoneurons) carry signals from the central nervous system to the outer parts (muscles, skin, glands) of your body.
Interneurons connect various neurons within the brain and spinal cord.The Peripheral Nervous
System is responsible for the remainder of the body. It includes cranial nerves (nerves emerging from the brain), spinal nerves (nerves emerging from the spinal cord) and all the major sense organs. The PNS includes:
The Somatic Nervous System (SNS) – Responsible for all muscular activities that we consider voluntary or that are within our conscious control.
The Autonomic Nervous System (ANS) – Responsible for all activities that occur automatically and involuntarily, such as breathing, muscle contractions within the digestive system, and heartbeat. The components of the ANS work together to create a balanced response to outside stimuli1. The ANS includes:
o The Sympathetic System – Stimulates cell and organ function. The sympathetic system is activated by a perceived danger or threat, very strong emotions such as fear, anger or excitement, by intense exercise, or when under large amounts of stress. Basically, anything the body perceives as an emergency will trigger a protective response. Once initiated, it speeds up heart rate, increases the activity of the sweat and adrenal glands, slows down the digestive system and sends blood to the skin and muscles; all of which prepare the body for a “fight or flight” response.
58
Fig. A. 7 AUTONOMIC NERVOUS SYSTEM
o The Parasympathetic System – Inhibits cell and organ function. The parasympathetic system slows down heart rate, resumes digestion, and increases relaxation throughout the body. This “rest and digest” response counteracts the “fight or flight” response and helps the body recuperate after a crisis is over. A person's normal resting heart rate is determined by the parasympathetic system. If blood pressure is too high or blood carbon dioxide levels are too low, this system slows the heart down and lowers its output.
Cranial Nerves:
The cranial nerves are so called because they are attached to the brain inside the skull (cranium). Some are sensory, some are motor and
others mixed. They leave the skull through various openings in the skull foramina.

The entire process of gas exchange in the body, called respiration, occurs in three basic steps:
1. Pulmonary ventilation, or breathing, is the flow of air into and out of the lungs
2. External respiration is the exchange of gases between the air spaces ( alveoli) of the lungs and the blood in pulmonary capillaries
3. Internal respiration is the exchange of gases between blood in systemic capillaries and tissue cells
Two parts: Upper respiratory system
-includes the nose, pharynx, and associated structures Lower respiratory system
-consists of the larynx, trachea, bronchi, and lungsTwo parts based on function:
Conducting zone -consists of a series of interconnecting cavities and tubes- nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles- that conduct air into the lungs
60
Respiratory zone - consists of tissues within the lungs where gas exchange occurs- the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli
Nose External nose -consists of bone and cartilage covered with skin and
lined with mucous membrane. It has to openings called the external nares or nostrils
Internal nose-connects to the throat through the two openings called the internal nares-four paranasal sinuses ( frontal, sphenoidal, maxillary, ethmoidal) and the nasolacrimal ducts also connect to the internal nose
Pharynx -funnel- shaped tube that that starts in internal nares and extends partway down the neck-lies just posterior to nasal and oral cavities and just anterior to the cervical neck-functions as a passageway for air and food-it has three portions: nasopharynx, oropharynx, laryngopharynx
Larynx-or voice box, is a short tube of cartilage lined by mucous membrane-connects the pharynx with the trachea-thyroid cartilage: consists of hyaline cartilage, forms the anterior wall of the larynx-epiglottis: routes food in to the esophagus -cricoid cartilage: a ring of hyaline cartilage that forms the inferior wall of the larynx and is attached to the first tracheal cartilage
Trachea-or wind pipe, is a tubular passageway for air that is located anterior to the esophagus-extends from the larynx to the upper part of the fifth thoracic vertebra, where it divides to right and left primary bronchi-walls are lined with mucous membrane and is supported by a cartilage-mucous membrane is composed of pseudostratified cilated columnar epithelium, consisting of ciliated columnar cells, goblet cells, and basal cells-cilia in the lower respiratory tract move mucus and trapped particles up toward the pharnx-cartilage layer consists of 16 to 20 C-shaped rings of hyaline cartilage tacked one on top of another- solid parts of the C-shaped cartilage rings provide rid support so the tracheal wall does not collapse inward and obstruct the air passageway
Bronchi and Bronchioles -contain incomplete rings of cartilage and are lined by pseudostratified ciliated columnar epithelium -pulmonary blood vessels, lymphatic vessels, and nerves enter and exit the lungs with the two bronchi-branching of the bronchial tree:
Trachea
61
Primary bronchi
Secondary bronchi
Tertiary bronchi
Bronchioles
Terminal Bronchioles
Lungs-two spongy, cone- shaped organs in the thoracic cavity-separated from each other by the heart and other structures in the mediastenum-pleural membrane: double- layered serous membrane that encloses and protects each lung-parietal pleura: outer layer is attached to the wall of the thoracic cavity and diaphragm-visceral pleura: inner layer and is attached to the lungs-pleural cavity: contains the lubricating fluid secreted by the membranes-each lung lobe is divided into smaller segments that are supplied by a tertiary bronchus-the segments in turn, are subdivided into many small compartments called lobules-terminal bronchioles subdivide into microscopic branches called respiratory bronchioles-respiratory bronchioles, in turn, subdivide into several alveolar ducts- the two or more alveoli that share a common opening to the alveolar duct are called alveolar sacs
Alveoli
cup- shaped out pouching of the alveolar sac walls consist mainly of thin alveolar cells, which area simple
squamous epithelium main sites for gas exchange lungs contain roughly 300 million alveoli, providing huge surface
area for gas exchange scattered among them are surfactant- secreting cells that secrete
alveolar fluid, which keps the surface betwwen cells and air moist included in the alveolar fluid is surfactant that reduces the
tendency of alveoli to collapse around the alveoli, the pulmonary arteriole and venule form lush
networks of blood capillaries exchange of oxygen and carbon dioxide between the air spaces in the
lungs and the blood takes place by diffusion across the alveolar and capillary walls
respiratory membrane consists of the following layers: The alveolar cells which form the wall of an alveolus The epithelial basement membrane underlying the alveolar cells
62
A capillary basement membrane that is often fused to the epithelial basement membrane
The endothelial cells of a capillary respiratory membrane is as thin as of tissue paper which permits
oxygen and carbon dioxide to diffuse efficiently between the blood and alveolar air spaces
PULMONARY VENTILATION
flow of air between the atmosphere and the lungs occurs due to differences in air pre contraction and relaxation of skeletal muscles create the air
pressure changes that power breathingExternal Respiration: Pulmonary Gas Exchange
is the diffusion of oxygen from air into the alveoli of the lungs to blood in pulmonary capillaries and the diffusion oxygen diffuses from alveolar air where its partial pressure is 105mm Hg, into the blood in pulmonary capillaries, where partial pressure of oxygen is about 40mm Hg in a resting person
Internal Respiration: Systemic Gas Exchange left ventricle pumps oxygenated blood into the aorta and through the systemic arteries to systemic capillaries as oxygen leaves the blood stream, oxygenated blood is converted into deoxygenated blood occurs in tissues throughout the body due to pressure differences, oxygen diffuses out of the capillaries into tissue cells, and blood partial pressure of oxygen decreases deoxygenated blood then returns to the heart for another process of external respirationTransport of Oxygen
heme part of hemoglobin contains four atoms of iron, each capable of binding to a molecule of oxygen in systemic capillaries, where partial pressure of oxygen is lower, hemoglobin releases oxygen which then can diffuse from blood plasma into interstitial fluid and into tissue cellsCarbon Dioxide Transport
Transported in three main forms: Dissolved carbon dioxide- dissolved in blood plasma. Upon reaching the lungs, it diffuses into alveolar air and is exhaled Bound to amino acids- most prevalent protein in the blood is the hemoglobin, most carbon dioxide transported to this manner is bound to hemoglobin( carbaminohemoglobin ) Bicarbonate ions- as carbon dioxide diffuses into tissue capillaries and enters the red blood cells, it combines with water to form carbonic acid
Integumentary System
63
Epidermis
outer layer of skin.
Four principal types of cells:
keratinocytes (90%)- produces the protein keratin that helps protect skin and underlying tissues from heat, microbes, and chemicals
melanocytes (8%)- produce the pigment melanin that contributes to skin color and absorbs damaging ultraviolet lights
Langerhan cells- participates in immune responses Merkel cells- detect different aspects of touch sensations
Dermis
composed mainly of connective tissue containing collagen and elastic fiber
surface area is greatly influenced by small, fingerlike projections dermal papillae
all present in the dermal papillae are free nerve endings deeper part attached to the subcutaneous layer, consists of dense
irregular connective tissue combination of collagen and elastic fibers in the deeper part of the
dermis provides the skin with strength, extensibility ( ability to stretch ), and elasticity (ability to return to original shape after stretching)
Hypodermis
not a skin layer but lies below the dermis a subcutaneous tissue contains fat, blood vessels and sensory receptors
FUNCTIONS OF THE SKIN:
1. Body temperature regulation – by liberating sweat at its surface and by adjusting the flow of blood in the dermis
2. Protection – keratin in the skin protects underlying tissues and the tightly interlock keratinocytes resist invasion by microbes. Lipids released by lamellar granules inhibit evaporation of water from the skin surface thus, protecting the body from dehydration. Oily sebum prevents hairs from drying out and contains bactericidal chemicals that kill surface bacteria. The acidic pH of perspiration retards the growth of some microbes. Melanin provides some protection against the damaging effects of ultraviolet light. Hair and nails also have protective function
3. Cutaneous sensations – include tactile sensation- touch, vibration, sensation, tickling- as well as thermal sensations such as warmth and coolness. Pain is usually an indication of impending or actual tissue damage
4. Excretion and absorption – excretion is the elimination of substances from the body while absorption is the passage of materials from the external environment to body cells
Accessory skin structures
64
Fig. A. 9 INTEGUMENTARY SYSTEM
The skin has the following appendages:
Skin Appendage
Structure Function
Hair
Hairs originate in the dermis and are shafts of modified keratinized epithelium which grow from the roots of hair follicles.
Sensory role, retains heat of the head and protects it from UV, advertises sexual maturity and disperses scents.
Arrector pili muscles
Smooth muscle cells which extend from the hair follicle to the papillary layer of the dermis.
Cause the hair to stand on end - "Goose Bumps".
Sweat glands
There are two types; merocrine and apocrine. They consist of coiled tubes embedded in the dermis or hypodermis and open out onto the skin surface.
Produce a watery substance to cool the body, excretion of wastes, excretion of body scents.
Nails
The nail plate is composed of dead hard keratinized cells which lie on top of a nail bed and which grow from the nail matrix under the skin.
Allows the tips of our fingers to be soft and sensory. They serve as tools to aid in the manipulation of objects.
Sebaceous glands
Flask shaped glands, located in the dermis and open into the hair follicles.
Produce sebum, an oily secretion which prevents the hair and skin becoming dry.
AGING AND INTEGUMENTARY SYSTEM
collagen fibers begin to decrease in number, stiffen, break apart, and disorganize into a shapeless, matted tangle
elastic fibers lose some of their elasticity, thicken into clumps, and fray
fibroblasts, which produce both collagen and elastic fibers, decrease in number
as a result, the skin forms the characteristic crevices and furrows known as wrinkles
Langerhan cells dwindle and macrophages become less- efficient phagocytes, thus decreasing the skin’s immune responses
decreased size of sebaceous glands lead to dry and broken skin that is more susceptible to infection
production of sweat diminishes, which probably contributes to increased incidence of heat stroke in the elderly
decrease number of functioning melanocytes results in gray hair and atypical skin pigmentation
increase in the size of some melanocytes produces pigmented blotching (age spots)
walls of blood vessels in the dermis become thicker and less permeable, and subcutaneous fat is lost
with the onset of old age, skin heals poorly and becomes more susceptible to pathological conditions
LYMPHATIC SYSTEM
65
consists of lymph, lymphatic vessels, a number of structures and organs containing lymphatic tissue, and bone marrowPrmary functions:
1. Draining excess interstitial fluid 2. Transporting dietary lipids 3. Carrying out immune responses
LYMPHATIC ORGAN AND TISSUESThymus
two- lobed organ located posterior to the sternum and medial to the lungs and superior to the heart
contains large numbers of T cells and scattered dendritic cells, epithelial cells, and macrophages
immature T cells migrate from red bone marrow to the thymus where they multiply and begin to mature
mature T cells leave the thymus via the blood and are carried to lymph nodes, the spleen, and other lymphatic tissues
Lymph nodes bean- shaped and is located along lymphatic vessels scattered throughout the body, both superficially and deep, and
usually occur in groups lymph flows through the node, substances are trapped by reticular
fibers within the spaces between cells macrophages destroy some foreign substances by phagocytosis, and
lyphocytes destroy others by a variety of immune responcesSpleen
largest single mass of lymphatic tissue in the body lies between the stomach and diaphragm and is covered by a capsule of
dense connective tissue contains two types of tissue called white pulp and red pulp white pulp, a lymphatic tissue consisting mostly of lymphocytes and
macrophages red pulp consists of blood-filled venous sinuses and cords of
spleenic tissue consisting of red blood cells, macrophages, lymphocytes, plasma cells, and granular leukocytes
Lymphatic nodules egg-shaped masses of lymphatic tissue that aresurrounded by a capsule
66
Fig. A. 10 LYMPHATIC SYSTEM
some occur as large aggregations in specific parts of the body, for example:
1. tonsils in the pharyngeal region2. aggregated lymphatic follicles ( Peyer's pathches )3. in the appendix
The human lymphoid system has the following:
primary organs: bone marrow (in the hollow center of bones) and the thymus gland (located behind the breastbone above the heart), and
secondary organs at or near possible portals of entry for pathogens: adenoids, tonsils, spleen (located at the upper left of the abdomen), lymph nodes (along the lymphatic vessels with concentrations in the neck, armpits, abdomen, and groin), Peyer's patches (within the intestines), and the appendix.
IMMUNE SYSTEM
An antigen is any substance that elicits an immune response, from a virus to a sliver.
The immune system has series of dual natures, the most important of which is self/non-self recognition. The others are: general/specific, natural/adaptive = innate/acquired, cell-mediated/humoral, active/passive, primary/secondary.
Parts of the immune system are:
67
Fig. A. 11. IMMUNE SYSTEM
Normal Adult Blood Cell Counts
Red Blood Cells
5.0*106/mm3
Platelets 2.5*105/mm3
Leukocytes 7.3*103/mm3
Neutrophil 50-70%
Lymphocyte 20-40%
Monocyte 1-6%
Eosinophil 1-3%
Basophil <1%
antigen-specific - they recognize and act against particular antigens systemic - not confined to the initial infection site, but work
throughout the body, and have memory - recognize and mount an even stronger attack to the same
antigen the next time.
Self/non-self recognition is achieved by having every cell display a marker based on the major histocompatibility complex (MHC). Any cell not displaying this marker is treated as non-self and attacked. The process is so effective that undigested proteins are treated as antigens.
Sometimes the process breaks down and the immune system attack self-cells. This is the case of autoimmune diseases like multiple sclerosis, systemic lupus erythematosus, and some forms of arthritis and diabetes. There are cases where the immune response to innocuous substances is inappropriate. This is the case of allergies and the simple substance that elicits the response is called an allergen.
Fluid Systems of the Body
There are two main fluid systems in the body: blood and lymph. The blood and lymph systems are intertwined throughout the body and they are responsible for transporting the agents of the immune system.
Immunity can be either natural or artificial, innate or acquired=adaptive, and either active or passive.
Active natural (contact with infection): develops slowly, is long term, and antigen specific.
Active artificial (immunization): develops slowly, lasts for several years, and is specific to the antigen for which the immunization was given.
Passive natural (transplacental = mother to child): develops immediately, is temporary, and affects all antigens to which the mother has immunity.
Passive artificial (injection of gamma globulin): develops immediately, is temporary, and affects all antigens to which the donor has immunity.

THEORETICAL BACKGROUNDDiabetes Type 2
Diabetes mellitus is a chronic multisystem disease related to abnormal insulin production, impaired insulin utilization, or both. Type 2 diabetes mellitus is, by far, the most prevalent type of diabetes. Type 2 diabetes usually occurs in people over 35 years of age, and 80% to 90% of patients are overweight at the time of diagnosis. However, because of the epidemic of childhood obesity, type 2 diabetes is now being seen in children. It has a tendency to run in families and probably has a genetic basis.
Prevalence of type 2 diabetes increases with age, with about half of the people diagnosed being older than 55. In the past, type 2 diabetes was known as “adult-onset” diabetes.
Prevalence of type 2 diabetes is greater in some ethnic populations. African Americans, Asian Americans Hispanic Americans, and Native Americans have a higher rate of this type of diabetes than whites.
Etiology and Pathophysiology
In type 2 diabetes, the pancreas usually continues to produce some endogenous (self-made) insulin. However, the insulin that is produced is either insufficient for the needs of the body and/or is poorly utilized by the tissues. (See Figure 3. B. 1) In contrast, there is a virtual absence of endogenous insulin in type 1 diabetes. The presence of endogenous insulin is the major pathophysiologic distinction between type 1 and type 2 diabetes.
69
Figure 3. B. 1Glucose transport to cell
membrane
A multitude of factors contribute toward the development of type 2 diabetes. The most powerful risk factor is believed to be obesity, specifically abdominal and visceral adiposity. Also, genetic mutations that lead to insulin resistance and higher risk for obesity have been found in many people with type 2 diabetes. It is likely that multiple genes are involved in this complex, multifactorial disorder.
Four major metabolic abnormalities have a role in the development of type 2 diabetes. The first factor is insulin resistance in glucose and lipid metabolism, which is a condition in which body tissues do not response to the action of insulin. This is due to insulin receptors that are either unresponsive to the action of insulin and/or insufficient in number.
A second factor in the development of type 2 diabetes is marked decrease in the ability of the pancreas to produce insulin, as the B-cells become fatigued from the compensatory overproduction of insulin or when B-cell mass is lost.
A third factor is inappropriate glucose production by the liver. Instead of properly regulating the release of glucose in response to blood levels, the liver does so in a haphazard way that does not correspond to the body’s needs at the time.
A fourth factor is alteration in the production of hormones and cytokines by adipose tissue (adipokines). Adipokines appear to play a role in glucose and fat metabolism and are likely to contribute to the pathophysiology of type 2 diabetes.
Individuals with metabolic syndrome are at an increased risk for the development of type 2 diabetes. Metabolic syndrome is a cluster of abnormalities that act synergistically to greatly increase the risk for cardiovascular disease and diabetes. Metabolic syndrome is characterized by insulin resistance, elevated insulin levels, high levels of triglycerides, decreased levels of high-density lipoproteins (HDLs), increased levels of low-density lipoproteins (LDLs), and hypertension.
Risk Factors
One has a higher risk for diabetes if one has any of the following:
Age greater than 45 years Diabetes during a previous pregnancy Excess body weight (especially around the waist) Family history of diabetes Given birth to a baby weighing more than 9 pounds HDL cholesterol under 35 mg/dL High blood levels of triglycerides, a type of fat molecule (250
mg/dL or more) High blood pressure (greater than or equal to 140/90 mmHg) Impaired glucose tolerance Low activity level (exercising less than 3 times a week) Metabolic syndrome Polycystic ovarian syndrome A condition called acanthosis nigricans, which causes dark,
thickened skin around the neck or armpits
70
Persons from certain ethnic groups, including African Americans, Hispanic Americans, Asian Americans, and Native Americans, have a higher risk for diabetes.
Clinical Manifestations
The clinical manifestations of type 2 diabetes are often nonspecific, although it is possible that an individual with type 2 diabetes will experience some of the classic symptoms associated with type 1. Some of the more common manifestation associated with type 1 diabetes include fatigue, recurrent infections, recurrent vaginal yeast or monilia infectious, prolonged wound healing, and visual changes. Unfortunately, the clinical manifestations appear o gradually that an individual may blame the symptoms on another cause, such as lack of sleep or increasing age, and before the person knows it, he or she may have complications.
Diagnostic Studies
Fasting blood glucose level ≥ 126 mg/dl (7.0 mmol/L). Fasting is defined as no caloric intake for at least 8 hours.
Random, or casual, plasma glucose measurement ≥ 200 g/dl (11.1 mmol/L), plus manifestation of diabetes, such as polyuria, polydipsia, and unexplained weight loss. Casual is defined as any time of day without regard to the time of the last meal.
Two-hour OGTT level ≥ 200 mg/dl (11.1 mmol/L), using a glucose load of 75 g.
The fasting plasma glucose (FPG) test, confirmed by repeat testing on another day, is the preferred method of diagnosis. When overt symptoms of hyperglycemia (polyuira, polydipsia, and polyphagia) coexist with FPG levels of 126 mg/dl (7.0 mmol/L) or greater, further testing using the OGTT may not be necessary to make a diagnosis.
Collaborative Care
The goals of diabetes management are to reduce symptoms, promote well-being, prevent acute complications of hyperglycemia, and prevent or delay the onset and progression of long-term complications. These goals are most likely to be met when the patient is able to maintain blood glucose levels as near to normal as possible. Diabetes is a chronic disease that requires daily decisions about food intake, blood glucose testing, medication, and exercise. Patient teaching, which enables the patient to become the most active participant in his or her own care, is essential for a successful treatment plan. Nutritional therapy, drug therapy, exercise, and self-monitoring of blood glucose are the tools used in the management of diabetes.
The major types of glucose-lowering agents (GLAs) used in the treatment of diabetes are insulin and oral agents (OAs). All individuals with type 1 diabetes require insulin. For some people with type 2 diabetes, a regimen of proper nutrition, regular physical activity, and maintenance of desirable body weight will be sufficient to attain an optimal level of blood glucose control.
71
Some of the most common types of medication are listed below. They are taken by mouth or injection.
Alpha-glucosidase inhibitors (such as acarbose) Biguanides (Metformin) Injectable medicines (including exenatide, mitiglinide,
pramlintide, sitagliptin, and saxagliptin) Meglitinides (including repaglinide and nateglinide) Sulfonylureas (like glimepiride, glyburide, and tolazamide) Thiazolidinediones (such as rosiglitazone and pioglitazone).
(Rosiglitazone may increase the risk of heart problems).
Diabetic Retinopathy
Etiology and Pathophysiology:
Diabetic Retinopathy refers to the process of microvascularization damage to the retina as a result of chronic hyperglycemia with Diabetes. (See Figure 3. B. 3). After 15 years of Diabetes Mellitus, nearly all patients with type I Diabetes and 80% with type II Diabetes will have some degree of retinal diseases. Diabetic Retinopathy is estimated to be the most common cause of new cases of blindness in people ages 20-74 years.
Retinopathy can be classified as non proliferative or proliferative. In non proliferative retinopathy, the most common form, partial occlusion of the small blood vessels in the retina causes the development of microaneurysms in the capillary walls. The walls of these microaneurysms are so weak that capillary fluid leaks out, causing retinal edema and eventually hard exudates of intra retinal hemorrhage. Vision may be affected if the macula is involved.
Proliferative retinopathy, the most severe form, involves the retina and the vitreous. When retinal capillaries become occluded, the body compensates by forming new blood vessels to supply the retina with blood, a pathologic process known as neovascularization. These new vessels are extremely fragile and hemorrhage easily, producing vitreous contraction. Eventually, light is prevented from reaching the retina as the vessels become torn and bleed into the vitreous cavity. The patient sees black or red spots or lines. If these new blood vessels pull the retina while the vitreous contracts, causing a tear, partial or complete retinal detachment will occur. If the macula is involved, vision is lost. Without treatment, more than half of patients with proliferative diabetic retinopathy will be blind.
Collaborative Care:
72
Table 3. B. 2Diabetic Retinopathy
The earliest and most treatable stages of Diabetic Retinopathy often produce no changes in the vision. Because of this, the patient with Diabetes must have regular dilated eye examination by an ophthalmologist or specially trained optometrists. As the time of diagnosis and annually thereafter for early detection and treatment.
The most common forms of treatment for Diabetic Retinopathy are early photocoagulation of the retina, cryotherapy, and vitrectomy. Photocoagulation by laser destroys the ischemic areas of the retina that produce growth factors that encourage neovascularization, thereby preventing further visual loss.
Cryotherapy is sometimes used to treat peripheral area of the retina that cannot be reached with lasers or with retinal hemorrhage prevents complete photocoagulation. (See. Figure 3. B. 3)
In this procedure, topical anesthesia is used so that a cryoprobe can be placed directly on the surface of the eye. When the probe is properly located, its tip creates a frozen area that extends through the external tissue through the eyeball until it reaches a specific point on the retina. Multiple points on the retina can be treated in this way.
Vitrectomy is the aspiration of blood, membrane and fibers from the inside of the eye through a small incision just behind the cornea. Vitrectomy is indicated when there is vitreal hemorrhage that does not clear in 6 months or when there is threatened or actual retinal detachement. (See Figure 3. B. 4)
Persons with Diabetes are also prone to other visual problems. Glaucoma occursa result of the occlusionof the outflow channels secondary to neovascularization. This type of glaucoma is difficult to treat and often results in blindness. Cataracts develop at an early age and progress more rapidly in people with Diabetes.
End-Stage Renal Disease

Definition
Chronic kidney disease (CKD) involves progressive, irreversible loss of kidney function. It is defined as either the presence of kidney damage of glomerular filtration rate (GFR), 60ml/min for 3 months or longer. (Normal GFR is about 125 ml/min and is reflected by urine creatinine clearance measurements. Kidney damage is defined as either pathologic abnormalities or markers of damage, including abnormalities in blood or urine test or imaging studies.
The last stage of kidney failure or End-stage kidney disease (ESRD) is the complete or almost complete failure of the kidneys to work. (See Figure 3. B. 5) The kidneys remove waste and excess water from the body. This occurs when the GFR is less than 15ml/min. At this point renal replacement therapy (dialysis or transplantation) is required.
Etiology/ Cause
The most common causes of ESRD are diabetes and high blood pressure. These conditions can affect the kidneys.
ESRD almost always comes after chronic kidney disease. The kidneys may slowly stop working over 10 - 20 years before end-stage disease results
Symptoms may include:
Clinical manifestations of CKD are apparent in multiple body systems. Fatigue, lethargy, and pruritus are often the early symptoms of CKD. Hypertension and proteinura are often the first signs.
Other symptoms may include:
Abnormally dark or light skin Nail changes Bone pain Drowsiness and confusion Problems concentrating or thinking Numbness in the hands, feet, or other areas Muscle twitching or cramps Breath odor Easy bruising, nosebleeds, or blood in the stool Excessive thirst Frequent hiccups Low level of sexual interest and impotence Menstrual periods stop (amenorrhea) Sleep problems, such as insomnia, restless leg syndrome,
or obstructive sleep apnea Swelling of the feet and hands (edema) Vomiting, especially in the morning
Diagnostic Studies
74
Figure 3. B. 5Kidney Disease
Adverse outcomes of CKD can be often prevented or delayed through early detection and treatment. Because persistent proteinuria is usually the first indication of kidney damage, screening of CKD involves a dipstick evaluation of protein in the urine. A person with persistent proteinura (1+ protein on standard dipstick testing two or more times over a 3 month period) should have further assessment of risk factor and diagnostic workup with blood and urine test.
A urine tests for albumin to creatinine ratio provides an accurate estimate of the protein and albumin excretion rate. A ratio greater than 300 mg albumin per 1 gram creatinine signals CKD. A urinalysis can detect RBCs, WBCs, protein, cast on glucose. Imaging of the kidneys to exclude obstruction and note size of the kidneys is usually achieved by ultrasound.
Treatment/ Prevention
Dialysis or kidney transplantation is the only treatment for this condition. Doctors may also put you on medicine to control the blood pressure.
Other treatment depends on symptoms but may include:
Extra calcium and vitamin D (always talk to the health care provider before taking)
Medicines called phosphate binders, to help prevent phosphorous levels from becoming too high
Treatment for anemia, such as extra iron in the diet, iron pills or shots, shots of a medicine called erythropoietin, and blood transfusions.
Hypertensive Cardiovascular Disease
Hypertensive heart disease refers to heart problems that occur because of high blood pressure. These problems include:
Coronary artery disease Heart failure Thickening of the heart muscle
Causes/ Etiology
High blood pressure increases the pressure in blood vessels. As the heart pumps against this pressure, it must work harder.Over time, this causes the heart muscle to thicken. The heart must work harder to pump blood out to the body. Without treatment, symptoms of congestive heart failure may develop.
75
Figure 3. B. 6Heart Disease
High blood pressure can cause ischemic heart disease because the thicker heart muscle needs an increased supply of oxygen.High blood pressure also contributes to thickening of the blood vessel walls. This may worsen atherosclerosis(increased cholesterol deposits in the blood vessels). This also increases the risk of heart attacks and stroke.
Hypertensive heart disease is the leading cause of illness and death from high blood pressure. The heart complications that develop determine the symptoms, diagnosis, treatment, and outlook of hypertensive heart disease.
Risk Factors
Age. Simply getting older increases your risk of damaged and narrowed arteries and weakened or thickened heart muscle, which contribute to heart disease.
Sex. Men are generally at greater risk of heart disease. However, the risk for a woman increases after menopause.
Family history. A family history of heart disease increases your risk of coronary artery disease, especially if a parent developed it at an early age (before age 55 for a male relative, such as your brother or father, and 65 for a female relative, such as your mother or sister).
Smoking. Nicotine constricts your blood vessels, and carbon monoxide can damage their inner lining, making them more susceptible to atherosclerosis. Heart attacks are more common in smokers than in nonsmokers.
Poor diet. A diet that's high in fat, salt and cholesterol can contribute to the development of heart disease.
High blood pressure. Uncontrolled high blood pressure can result in hardening and thickening of your arteries, narrowing the vessels through which blood flows.
High blood cholesterol levels. High levels of cholesterol in your blood can increase the risk of formation of plaques and atherosclerosis. Plaques can be caused by a high level of low-density lipoproteins (LDLs), known as "bad" cholesterol, or a low level of high-density lipoproteins (HDLs), known as "good" cholesterol.
Diabetes. Diabetes increases your risk of heart disease. Both conditions share similar risk factors, such as obesity and high blood pressure.
Obesity. Excess weight typically worsens other risk factors.
Physical inactivity. Lack of exercise also is associated with many forms of heart disease and some of its other risk factors, as well.
High stress. Unrelieved stress in your life may damage your arteries as well as worsen other risk factors for heart disease.
Poor hygiene. Not regularly washing your hands and failure to establish other habits that can help prevent viral or bacterial infections can put you at risk of heart infections, especially if you already have an underlying heart condition. Poor dental health also may contribute to heart disease.
76
Clinical Manifestations
It usually takes some time for the problem of high blood pressure to eventually lead to hypertensive cardiovascular disease and therefore high blood pressure is often called the silent killer. Eventually hypertensive heart disease can also lead to congestive heart failure. Some symptoms of hypertension and the eventual congestive heart failure include arrhythmias, shortness of breath, weakness and fatigue, swelling in lower extremities and greater frequency of urination during the night. Hypertensive cardiovascular disease may also result in ischemic heart condition and in this case there might be chest pain, sweating and dizziness, nausea and shortness of breath. Hypertrophic cardiomyopathy could also be a result of hypertensive heart disease.
Signs/ Tests
Tests to diagnose heart disease can include:
Electrocardiogram Urinalysis Blood glucose and hematocrit levels Serum potassium, creatinine (or the corresponding estimated
glomerular filtration rate [GFR]), and calcium measurements Lipid profile after a 9- to 12-hour fast - Includes high density
lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides
Optional tests - Include measurement of urinary albumin excretion or albumin/creatinine ratio
Treatment/ Prevention
The primary aim of any treatment in hypertensive cardiovascular disease is reduction of blood pressure and then eventual control of the heart disease. The line of treatment will ordinarily depend on the condition such as whether there is angina or acute myocardial infarction. The line of treatment may include beta blockers, angiotensin converting enzyme inhibitors (ACE), calcium channel blockers, diuretics etc depending upon particulars of each individual case. The blood pressure is consistently required to be checked and kept under control in this condition.
In addition to medications, recommended lifestyle changes include:
Diet changes:o Avoid trans fats and saturated fatso Increase fruits, vegetables, and low-fat dairy productso Reduce salt intake (may be beneficial)o Eat whole grains, poultry, and fish
Exercise regularly Reduce excessive alcohol consumption Stop smoking -- cigarettes are a major cause of hypertension-
related heart disease Lose weight if you are overweight or obese
Coronary Artery Disease
77
This is a type of blood vessel disorder that is included in the general category of atherosclerosis. The term atherosclerosis is derived from two Greek words: athere, meaning “fatty mush,” and skleros, meaning “hard.” This combination indicates that atherosclerosis begins as soft deposits of fat that harden with age. Atherosclerosis is often referred to as, “hardening of the arteries.” Although this condition can occur in any artery in the body, the atheromas (fatty deposits) have a preference for the coronary arteries. Arteriosclerotic heart disease, cardiovascular heart disease, ischemic heart disease coronary heart disease, and CAD are all terms used to describe this disease process.
Etiology
Atherosclerosis is the major cause of CAD. It is characterized by a focal deposit of cholesterol and lipids, primarily within the intimal wall of the artery. The genesis of plaque formation is the result of complex interaction between the components of the blood and the elements forming the vascular wall. Inflammation and endothelial injury play a central role in the development of atherosclerosis. Intact normal endothelium is more than a simple barrier between the vessel wall and the lumen of the vessel. Normally, it is nonreactive to platelets and leukocytes, as well as coagulation, fibrinolytic and complement factors. However, the endothelial lining can be injured as a result of tobacco use, hyperlipidemia, hypertension, diabetes, hyperhomocysteinemia and infection causing a local inflammatory response.
C-reactive protein (CRP), a nonspecific marker of inflammation is increased in many patients with CAD. Chronic exposure to even minor elevations of CRP can trigger the rupture of plaques and promote the oxidation of low-density lipoprotein cholesterol leading to increase uptake by macrophages in the endothelial lining.
Developmental changes
Fatty streaks, the earlier lesions of atherosclerosis, are characterized by lipid-filled smooth muscle cells. As streaks of fat develop within the smooth muscle cells, a yellow tinge appears.
Fatty streaks can be observed in the coronary arteries by age 15 and involve an increasing amount of surface area as the patient ages. It is generally believed that treatment that lowers LDL cholesterol may reverse this process.
Fibrous plaque stage is the beginning of progressive changes in the endothelium of the arterial wall. These changes can appear
78
Figure 3. B. 7
in the coronary arteries by age 30 and increase with age. Normally, the endothelium repairs itself immediately, but in the person with CAD the endothelium is not rapidly replaced, allowing LDL’s and growth factors from platelets to stimulate smooth muscle proliferation, and thickening of the arterial wall.
Once endothelial injury has occurred, lipoproteins (carrier proteins within the bloodstream) transport cholesterol and other lipids into the arterial intima. The fatty streak is eventually covered by collagen forming a fibrous plaque that appears grayish or whitish. These plaques can form on one portion of the artery or in a circular fashion, involving the entire lumen. The borders can be smooth or irregular with rough, jagged edges. The result is a narrowing of the vessel lumen and a reduction in blood flow to the distal tissues.
Complicated lesion. The final stage in the development of the atherosclerotic lesion is the most dangerous. As the fibrous plaque grows, continued inflammation can result in plaque instability, ulceration and rupture.
Once the integrity of the artery’s inner wall has become compromised, platelets accumulate in large numbers, leading to a thrombus. The thrombus may adhere to the wall of the artery, leading to further narrowing or total occlusion of the artery. Activation of the exposed platelets causes expression of glycoprotein IIb/IIIa receptors that bind fibrinogen. This, in turn leads to further platelet aggregation and adhesion, further enlarging the thrombus. At this stage, the plaque is referred to as complicated lesion.
Collateral circulation. Normally some arterial anastomoses or connection, termed collateral circulation, exist with the coronary circulation. The growth and extent of collateral circulation are attributed to two factors: 1) the inherited predisposition to develop new blood vessels (angiogenesis) and 2) the presence of chronic ischemia. When an atherosclerotic plaque occludes the normal flow of blood through a coronary artery and the resulting ischemia is chronic, increased collateral circulation develops. When occlusion of the coronary arteries occurs slowly over a long period, there is a greater chance of adequate collateral circulation developing, and the myocardium may still receive an adequate amount of blood and oxygen.
However the rapid onset of CAD or coronary spasm, the time is inadequate for collateral development and a diminished arterial flow results in a more severe ischemia or infarction. CAD develops over many, and clinical manifestation will not be apparent in the early stages of the disease. Therefore it becomes extremely important to identify people at risk so that therapeutic lifestyle changes and some treatment strategies can be initiated early.
Risk factors for coronary artery disease
Risk factors are characteristics or conditions that are statistically associated with a high incidence of a disease. Many risk factors have been associated with a high incidence of a disease. Many risk factors have been associated with CAD.
79
Risk factor may be categorized as nonmodifiable and modifiable. Nonmodifiable rik factors ar age, gender, ethnicity, family history, and genetic inheritance. Mofifiable risk factors include elevated serum lipids, hypertension, tobacco use, physical activity, obesity, diabetes, metabolic syndrome, psychologic states, and homocysteine level.
Treatment
Goals for treating these conditions in people who have coronary artery disease:
Blood pressure less than or equal to 140/90 (even lower for some patients with diabetes, kidney disease, or heart failure)
Glycosylated hemoglobin (HbA1c) levels less than or equal to 7% for people with diabetes
LDL cholesterol level less than or equal to 100 mg/dL (even lower for some patients)
Treatment depends on the symptoms and how severe the disease is. Medicines to treat CHD includes:
ACE inhibitors to lower blood pressure and protect the heart and kidneys
Aspirin, with or without clopidogrel (Plavix) or prasugrel (Effient) to help prevent blood clots from forming in the arteries
Beta-blockers to lower heart rate, blood pressure, and oxygen use by the heart
Calcium channel blockers to relax arteries, lower blood pressure, and reduce strain on the heart
Diuretics ("water pills") to lower blood pressure and treat heart failure
Nitrates (such as nitroglycerin) to stop chest pain and improve blood flow to the heart
Statins to lower cholesterol
Hypoxic Ischemic Encephalopathy
Definition
Hypoxic ischemic encephalopathy (HIE) is a condition in which the brain does not receive enough oxygen. This particular condition refers to an oxygen deficiency to the brain as a whole, rather than a part of the brain. Although the term most often refers to injury sustained by newborns, HIE can be used to described any injury from low oxygen.
HIE can be fatal. Within as little as five minutes of oxygen deprivation, brain cells can begin dying. The disease can also cause long-term damage, including intellectual disability , delayed development, seizures , and cerebral palsy
80
Figure 3. B. 8Comparison of normal brain
to that with HIE
Causes/ Etiology
There are a variety of causes of HIE. Any injury and many health conditions can potentially cause oxygen deprivation to the brain. Some common causes are:
Injury or complication during birth Respiratory failure Blocked or ruptured blood vessel Carbon monoxide or cyanide poisoning Drug overdose Drowning Lack of oxygen due to smoke inhalation Extremely low blood pressure Strangulation Cardiac arrest Carbon monoxide poisoning High altitudes Choking Compression or injury to the trachea that reduces or stops
breathing Complications from general anesthesia Diseases that cause paralysis of the respiratory organs or
muscles (eg, myasthenia gravis , Guillain-Barre syndrome )
Risk Factors
Any injury, complication, or condition that causes the brain to have a reduction in blood flow and oxygen deprivation is a risk factor for HIE.
Clinical Manifestations
Symptoms include:
Mild case: o Difficulty concentrating or paying attentiono Poor judgmento Poor coordinationo Euphoriao Extreme lethargy
Severe oxygen deprivation: o Seizureso Comao No brain stem reflexes (eg, breathing, responding to light)o Only blood pressure and heart function reflexes are functioning
Signs/ Tests
There are no specific tests to confirm or exclude a diagnosis of hypoxic-ischemic encephalopathy (HIE) because the diagnosis is made based on the history, physical and neurological examinations, and laboratory evidence. Many of the tests are performed to assess the severity of brain injury and to monitor the functional status of systemic organs. As always, the results of the tests should be
81
interpreted in conjunction with the clinical history and the findings from physical examination.
Laboratory studies should include the following:
Severe electrolyte imbalance- In severe cases, daily assessment of serum electrolytes is valuable until the infant's status improves. Markedly low serum sodium, potassium, and chloride levels in the presence of reduced urine flow and excessive weight gain may indicate acute tubular damage or syndrome of inappropriate antidiuretic hormone (SIADH) secretion, particularly during the initial 2-3 days of life.Similar changes may be seen during recovery; increased urine flow may indicate ongoing tubular damage and excessive sodium loss relative to water loss
Renal function studies - Serum creatinine levels, creatinine clearance, and BUN levels suffice in most cases.
Cardiac and liver enzymes - These values are an adjunct to assess the degree of hypoxic-ischemic injury to these other organs. These findings may also provide some insight into injuries to other organs, such as the bowel. In addition, early evidence suggests that cardiac troponin I may be correlated to HIE severity
Coagulation system evaluation - This includes prothrombin time, partial thromboplastin time, and fibrinogen levels.
ABG - Blood gas monitoring is used to assess acid-base status and to avoid hyperoxia and hypoxia as well as hypercapnia and hypocapnia.
Imaging Studies
Brain MRI - Decreased signal in the posterior limb of the internal capsule (PLIC) on T1w images may be noted. The absence of normal signal (high intensity on T1w images) in the PLIC of infants older than 38 weeks' gestation is a strong predictor of abnormal motor outcomes in these infants.
Cranial ultrasonography - Findings include global increase in cerebral echogenicity and obliteration of cerebrospinal fluid (CSF) containing spaces suggestive of cerebral edema.
Head CT scanning - Areas of reduced density that indicate evolving zones of infarction may be present. Evidence of hemorrhage in the ventricles or in the cerebral parenchyma may also be seen.
Treatment/ Prevention
Treatment depends on the underlying cause of the condition, as well as the severity of the damage to the brain. Treatment options include:
Life-sustaining treatment—If brain function has stopped but damage is not yet extensive, life-sustaining treatment is administered.
82
Mechanical ventilation —This may be needed to sustain breathing. Treatments for the circulatory system—Treatments are
administered to maintain heart function and control blood pressure.
Seizure control—Medicine and general anesthesia may be administered to control seizures.
Cooling—Hypoxic brain damage is often caused by heat. Cooling blankets or other means of cooling may be applied to reduce the body's temperature.
Hyperbaric oxygen treatment —This treatment is used in cases of carbon monoxide poisoning.
In most cases, HIE is unexpected and cannot be prevented. To prevent significant or long-term brain damage once the oxygen supply has been reduced, CPR may be administered.
Health-care related, Ventilator acquired and Aspiration Pneumonia
Definition It is an acute inflammation of the lung parenchyma cause by
microbial organisms.
Risk Factor predisposing to Pneumonia Resulting when defense mechanism become incompetence Virulence or quantity of infectious agent Decrease consciousness depressing epiglottal reflexes Tracheal intubation interfering normal cough reflex Impairment of mucousilliary mechanism due to air pollution,
cigarette smoking, viral upper respiratory infection and normal changes of aging
How to acquire pneumonia Aspiration Inhalation Hematogenous spread
Types of Pneumonia
1.Hospital – Acquired pneumonia Hospital-acquired pneumonia
occurring 48 hours or longer after hospital admission and not incubating at the time of hospitalization. (Figure 3. B. 9)
2.Ventilator associated- refers to pneumnonia that occurs more than 48-72 hours after endotracheal intubation.(Figure 3. B. 10)
3.Healthcare associated Pneumonia- includes any patients with a new onset of pneumonia: who was hospitalized in an acute health care hospital for 2 or more days with 90 days of infection,
83
Figure 3. B. 9
Figure 3. B. 10
resided in a long term care facility, received recent intravenous antibiotic therapy, chemotherapy, or wound care within the past 30 days of the current infection and attended a hospital or hemodialysis clinic.
Organisms associated with Hospital acquired and ventilator acquired pneumonia and how it is acquired:
Pseudomonas aeruginosa- common bacterium that can cause disease in animals, including humans. It is found in soil, water, skin flora, and most man-made environments or machines. (See Figure 3. B. 11)
Klebsiella pneumoniaE- gram-negative, nonmotile bacteria found in soil, water, cereal grains, and the intestinal tract of humans and other animals. commonly implicated in nosocomial urinary tract infections, especially in immunocompromised patients. (See Figure 3. B. 12)
Candida tropicalis- one of many types of yeasts that naturally exist within animals and humans, particularly in the gastrointestinal and urinary tract. (See Figure 3. B. 13)
Burkholderia cepacia- found naturally in wet soil and decaying plants, such as rotting onions. B. cepacia can live on surfaces such as sinks, counter tops, clothing and chairs for up to 2 hours if the droplets are dry and up to 24 hours if they are wet. While it is possible for B. cepacia to be transmitted through indirect contact with these objects, person to person contact is by far the most common mode of transmission. (See Figure 3. B. 14)
Risk Factors Alcoholism Being on a breathing machine Breathing saliva or food into the lungs (aspiration) Chest surgery Immunosuppression (immune system does not work well) Long-term (chronic) lung disease Not being fully alert Older age Recent illness Clinical Manifestations

b. PNSSGeneric name: 0.9% sodium chlorideBrand name: Normal saline solutionClassifications: Isotonic Intravenous SolutionContraindications: No known contraindications.Nursing Considerations:
-It should be use with great care, if at all, in all patients with congestive heart failure, severe renal insufficiency, and clinical state in which there is existing edema with sodium retention.
-Do not connect flexible plastic containers of IV solution in series connections, such as in air embolism due to residual that are being drawn from one container before administration of the fluid from a second container that is completed.
c. Isoket DripGeneric Name: Isosorbide DinitrateClassification:Anti-anginal, Nitrate, VasodilatorAction: Relaxes vascular smooth muscle with a resultant decrease in venous return and decrease arterial BP which reduces left
88
ventricular workload and decreases myocardial oxygen consumption.Indication: Treatment and prevention of angina pectorisContraindication: Hypersensitivity to Nitrates.Nursing Responsibility:
-Monitor effectiveness of drug in relieving angina.-Chronic administration of large doses may produce tolerance and thus decrease effectiveness of nitrate preparations.-Make position changes slowly, particularly from recumbent to upright posture, and dangle feet and ankles before walking.
d. Nicardipine dripClassification:anti-anginal, anti-hypertensive, channel blocker Action:
-Inhibits the movement of calcium ions across the membranes and arterial muscle cells.
-decreases cardiac work, decreases cardiac energy consumption, and increases delivery of oxygen to myocardial cells.Indication:
-Management of hypertension, chronic stable angina.Contraindication: Nursing Responsibility:
-Monitor vital signs carefully.-Report irregular heartbeat, shortness of breath, swelling
of hands or feet, dizziness, constipation.
2. OXYGEN THERAPY- The administration of oxygen at concentrations greater than that in ambient air with the intent of treating or preventing the symptoms and manifestations of hypoxia.
Hypoxia - the blood oxygen levels < 92%
Hypercapnia - increased carbon dioxide levels
Indication for oxygen therapy:
Any individual with one or more of the following:
Peri and post cardiac or respiratory arrest Hypoxia - diminished blood oxygen levels (oxygen
saturation levels of <92%) Acute and chronic hypoxemia (PaO2 < 65mmHg, SaO2 < 92%) Signs and symptoms of shock Low cardiac output and metabolic acidosis (HCO3 < 18mmol/l) Chronic type two respiratory failure (hypoxia and hypercapnia)
Despite a lack of supportive data, oxygen is also administered in the following conditions:
89
Dyspnea without hypoxemia Postoperatively, dependent on instruction from surgical team. Treatment of pneumothorax .
Method of administration oxygen given to patient:
Endotracheal tube-is a breathing tube. It is used temporarily for breathing because it keeps your airway open. This curved is placed through the patient’s nose or mouth into his trachea. Tape or soft strap holds the tube in place.
An endotracheal tube is used :
-To attach a ventilator if the patient is unable to breathe on its own.
-To keep the patient's trachea (windpipe) open.-To allow the staff to remove mucus from the patient's lungs that he is unable to cough up himself. -This can help when a patient is unconscious and by maintaining a patent airway, especially during surgery. -It is often used when patients are critically ill and cannot maintain adequate respiratory function to meet their needs. The endotracheal tube facilitates the use of a mechanical ventilator in these critical situations.
Nursing Responsibilty:- Suctioning down the tube every two hours or as needed.- The patient must also be monitored for skin breakdown in
either the oral or nasal cavity (depending on where the tube is inserted).
- Thorough oral care should be provided every eight hours and as needed.
- The tube should be repositioned so that it is not continuously exerting pressure in the same area.
- The tape must be removed and replaced on the opposite side of the face at least once per day and as needed.
Bag valve mask- Hand-held device used to provide positive pressure ventilation to a patient who is not breathing or who is breathing inadequately.
- used extensively in the operating room to ventilate an anaesthetized patient in the minutes before a mechanical ventilator is attached.
-The device is self-filling with air, although additional oxygen (O2) can be added.
90
-Flow-inflating bags — termed "anesthesia bags" or "flow-
inflating bags" these bags require an external flow source to
inflate.
-Self-inflating bags — the bag portion of the BVM is rigid
and self-inflates when released; this does not require an
external flow source.
Nursing Responsibilities:
- Synchronized with patients breathing pattern.
- Do not over inflate the bag. Risk
Oxygen is not addictive and causes no side effects when
used as prescribed. Complications from oxygen therapy used in
appropriate situations are infrequent. Respiratory depression,
oxygen toxicity, and absorption atelectasis are the most serious
complications of oxygen overuse.
A physician should be notified and emergency services may be
required if the following symptoms develop:
frequent headaches
anxiety
cyanotic (blue) lips or fingernails
drowsiness
confusion
restlessness
slow, shallow, difficult, or irregular breathing
3. BLOOD TRANFUSION THERAPY A blood transfusion is a safe, common procedure in which the
body receive blood through an intravenous (IV) line inserted into one of the blood vessels.
Blood transfusions are used to replace blood lost during surgery or a serious injury. A transfusion also might be done if the body can't make blood properly because of an illness.
During a blood transfusion, a small needle is used to insert an IV line into one of the blood vessels. Through this line, the body receive healthy blood. The procedure usually takes 1 to 4 hours, depending on how much blood is needed.
Packed RBC
91
- Used to restore oxygen carrying capacity to the blood of a patient that is suffering from anemia due to trauma or other medical problems.
- Carries oxygen from the lungs to the rest of the body.- One of the most important blood components used in transfusion
medicine. - Provides nutrients and preserves the functionality of the
living cells.
Nursing Responsibility:
- Insure that the right unit of blood is to be administered to the right patient after typing and cross matching by the lab by checking the lot, serial numbers, blood type, and expiration date.
- The unit of blood has to be checked off with another nurse before administration.
- Monitor vital signs of the patient.
3. Hemodialysis – Cleansing the blood of accumulated waste products. -One of the diagnosis of the patient was end stage renal disease so the kidney can no longer do its normal function.
Uses
1. Short term therapy in acutely ill clients2. Long term use in clients with end-stage renal disease
Hemodialysis requires five things:
1. Access to patient’s circulation (usually via fistula).2. Access to a dialysis machine and dialyzer with a semipermeable membrane.3. The appropriate solution (dialysate bath).4. Time: 12 hours each week, divided in 3 equal segments.5. Place: home (if feasible) or a dialysis center.
Three ways to access to client’s circulation for dialysis: Arteriovenous Fistula- A section of vein is directly
sutured to an artery. It is usually placed in the nondominant arm, using the cephalic vein and radial artery.
Arteriovenous Graft- Connection tube is client’s own (autologous) saphenous vein, or made from polytetrafluoroethylene (PTFE).
Central Venous Catheter- Catheter inserted by directly cannulating the vein. Usual CVC sites are: femoral, internal jugular, or subclavian veins.
Procedure for hemodialysis
1. Patient’s circulation is accessed2. Unless contraindicated, heparin is administered3. Heparinized (heparin: natural clot preventer) blood
92
flows through a semipermeable membrane in one direction4. Dialysis solution surrounds the membranes and flows in the opposite direction5. Dialysis solution is:a. Highly purified waterb. Sodium, potassium, calcium, magnesium, chloride and dextrosec. Either bicarbonate or acetate, to maintain a proper pH
6. Via the process of diffusion, wastes are removed in the form of solutes (metabolic wastes, acid-base components and electrolytes)7. Solute wastes can then be discarded or added to the blood8. Ultrafiltration removes excess water from the blood9. After cleansing, the blood returns to the client via the access.
Complications related to vascular access in Hemodialysis
1. Infection2. Catheter clotting3. Central venous thrombosis4. Stenosis or thrombosis5. Ischemia of the affected limb6. Development of an aneurysm
Nursing interventions for Hemodialysis
1. Explain procedure to client2. Monitor hemodynamic status continuously3. Monitor acid-base balance4. Monitor electrolytes5. Insure sterility of system6. Maintain a closed system7. Discuss diet and restrictions on:a. Protein intakeb. Sodium intakec. Potassium intaked. Fluid intake8. Reinforce adjustment to prescribed medications that may be affected by the process of hemodialysis9. Monitor for complications of dialysis related to:a. Arteriosclerotic cardiovascular diseaseb. Congestive heart failurec. Stroked. Infectione. Gastric ulcersf. Hypertensiong. Calcium deficiencies (bone problems such as aseptic
93
necrosis of the hip joint)h. Anemia and fatiguei. Depression, sexual dysfunction, suicide risk
Nursing Considerations:
Patient Preparation:1. Allow the client to void before catheter insertion.2. Institute abdominal skin preparation3. Document the client’s weight before the dialysis4. Take baseline vital signs
During the Procedure:1. Monitor the level of electrolytes.2. Obtain samples of return dialysate for culture3. Compare the client’s weight before and after the procedure4. Monitor the vital signs every 30 minutes and report any deviations5. Provide proper positioning for the dialysate to return from the
peritoneal cavity. Place the patient in semi-Fowler’s position.
5. Foley bag catheter-Urinary catheter is inserted into patient's bladder via his or her urethra.
-Catheterization allows the patient's urine to drain freely from the bladder for collection. It may be used to inject liquids used for treatment or diagnosis of bladder conditions. -The catheter may be a permanent one (indwelling catheter), or an intermittent catheter removed after each catheterization.
6. Nasogastric tube-Nasogastric intubation refers to the process of placing a soft plastic nasogastric (NG) tube through a patient's nostril, past the pharynx and down the esophagus into a patient's stomach.
Purpose:-Nasogastric tubes are inserted to deliver substances directly into the stomach, remove substances from the stomach or as a means of testing stomach function or contents.-To deliver tube feedings to a patient when they are unable to eat.- is used to remove air that accumulates in the stomach during cardiopulmonary resuscitation (CPR). -It is used to remove stomach contents after major trauma or surgery to prevent aspiration of the stomach contents. -Placing a NG helps prevent nausea and vomiting by removing stomach contents and preventing distention of the stomach when a patient has a bleeding ulcer, bowel obstruction or other gastrointestinal diseases.
94
Nursing Responsibility:
-Always check the tube positioning by instilling air
and listening for gurgling sounds using stethoscope
before giving feedings to prevent aspiration.
- Keep the patients in an upright or semi-upright
sitting position when delivering tube feeding to
enhance peristalsis and avoid regurgitation of the
feeding.
- Cap or clamp off the NG tube when not in use to
prevent backflow of stomach contents or accumulation
of air in the stomach..
- If the amount of gastric aspirate is more 100ml,
discontinue feeding.
- After feeding, position patient into high-fowlers
position for 30 minutes.
7. Suctioning-removing mucus and fluids from the nose, mouth, or back of the throat with a bulb syringe or a catheter (thin flexible tube). It aims to assist in the removal of bronchial secretions that cannot be expectorated by the patient spontaneously
Nursing Considerations: Maintain sterile technique while doing the procedure. Do not allow suctioning to continue for more than 10
seconds. Hyperventilate three to five times between suctioning or encourage patient to cough and deep breathe between suctioning.
Suctioning is important to prevent a mucus plug from blocking the tube and stopping the patient's breathing.
8. Complete Blood Count- A common blood test that evaluates the three major types of cells in the blood: red blood cells, white blood cells, and platelets.
Red blood cells: The CBC's measurements of red blood cell (RBC) count, hemoglobin (the oxygen-carrying protein in RBCs), and mean (red) cell volume (MCV) provides information about the RBCs, which carry oxygen from the lungs to the rest of the body. These measurements are usually done to test for anemia, a common condition that occurs when the body has insufficient red blood cells.
95
White blood cells: The white blood cell (WBC) count measures the number of WBCs (also called leukocytes) in the blood. The WBC differential test measures the relative numbers of the different kinds of WBCs in the blood. WBCs, which help the body fight infection, are bigger than red blood cells and there are far fewer of them in the bloodstream. An abnormal WBC count may indicate an infection, inflammation, or other stress in the body.
Platelets: The smallest blood cells, platelets play an important role in blood clotting and the prevention of bleeding. When a blood vessel is damaged or cut, platelets clump together and plug the hole until the blood clots. If the platelet count is too low, a person can be in danger of bleeding in any part of the body.
Purpose
- The CBC provides valuable information about the blood and to some extent the bone marrow which is the blood-forming tissue. The CBC is used for the following purposes:
As a preoperative test to ensure both adequate oxygen carrying capacity and homeostasis.
To identify persons who may have an infection. To diagnose anemia. To monitor treatment for anemia and other blood diseases.
Nursing Responsibility:- Identify patient, ask if the patient is taking anti-
coagulant medication like aspirin.- Assess the site for CBC test if skin was intact.- After the test, apply pressure for 15 minutes. - The result will be available after 1hour and the physician
will be the one who will explain for the results.- As a nurse, reinforced learning to both patient and
significant others.
9. Anti-embolism stockings Designed specifically for bed bound (non-ambulatory)
patients to help prevent blood from pooling in the veins of the leg. Pooling of blood in the veins of the leg may contribute to blood clots forming in the veins.
Made for short duration of wear during a hospitalization.
96
Provide graduated pressure on the lower leg and foot and, in some cases, the thigh, to alleviate circulatory problems such as edema, phlebitis and thrombosis.
Nursing Responsibilities
Do not offer anti-embolism stockings to patients who have: suspected or proven peripheral arterial disease
peripheral arterial bypass grafting
peripheral neuropathy or other causes of sensory impairment .
any local conditions in which stockings may cause damage, for example fragile ‘tissue paper’ skin, dermatitis, gangrene or recent skin graft.
known allergy to material of manufacture.
cardiac failure.
10. Mechanical Ventilator
a method to mechanically assist or replace spontaneous breathing.
divided into negative-pressure ventilation, where air is essentially sucked into the lungs, or positive pressure ventilation, where air (or another gas mix) is pushed into the trachea.
There are two main divisions of mechanical ventilation; Invasive ventilation, and non-invasive ventilation.
Negative Pressure Ventilation
This negative pressure leads to expansion of the chest, which causes a decrease in intrapulmonary pressure, and increases flow of ambient air into the lungs. As the vacuum is released, the pressure inside the tank equalizes to that of the ambient pressure, and the elastic coil of the chest and lungs leads to passive exhalation.
Positive Pressure Machine
Positive-pressure ventilators work by increasing the patient's airway pressure through an endotracheal or tracheostomy tube.
The positive pressure allows air to flow into the airway until the ventilator breath is terminated.
Indications
patient's spontaneous ventilation is inadequate to maintain life.
prophylaxis for imminent collapse of other physiologic functions, or ineffective gas exchange in the lungs.
Apnea with respiratory arrest, including cases from intoxication
97
Chronic obstructive pulmonary disease (COPD)
Acute respiratory acidosis with partial pressure of carbon
dioxide (pCO2) > 50 mmHg and pH < 7.25, which may be due to
paralysis of the diaphragm due to Guillain-Barré
syndrome,Myasthenia Gravis, spinal cord injury, or the effect
of anaesthetic and muscle relaxant drugs.
Increased work of breathing as evidenced by
significant tachypnea, retractions, and other physical signs of
respiratory distress
Hypoxemia with arterial partial pressure of oxygen (PaO2) <
55 mm Hg
Hypotension including sepsis, shock, congestive heart failure
Neurological diseases such as Muscular Dystrophy and Amyotrophic
Lateral Sclerosis
Complications
pneumothorax, airway injury alveolar damage ventilator-associated pneumonia.
Positive end-expiratory pressure
An adjuvant to the mode of ventilation used to help maintain functional residual capacity (FRC).
The PEEP exerts pressure to oppose passive emptying of the lung and to keep the airway pressure above the atmospheric pressure.
Indications
PEEP can cause significant haemodynamic consequences through
decreasing venous return to the right heart and decreasing right
ventricular function.
If a PaO2 of 60 mmHg cannot be achieved with a FiO2 of 60%
If the initial shunt estimation is greater than 25%
The nurse must be able to do the following:
- Identify the indications for mechanical ventilation.- List the steps in preparing a patient for intubation.- Determine the FIO2, tidal volume, rate and mode of ventilation
on a given- ventilator.- Describe at least two complications associated with patient’s
response to mechanical ventilation and their signs and symptoms.
98
- Describe the causes and nursing measures taken when trouble-shooting ventilator alarms.
- Describe preventative measures aimed at preventing selected other complications related to endotracheal intubation.
- Complete the care of the ventilated patient checklist.
SURGICAL MANAGEMENT
a. Venous cut down-an emergency procedure in which the vein is exposed
surgically and then a cannula is inserted into the vein under direct vision. It is used to get vascular access in trauma and hypovolemic shock patients when peripheral cannulation is difficult or impossible.
Nursing Responsibility:
- Assess the dressing after the procedure.- Note for any signs of infection on the site like
redness and swelling and fever.- Change dressing regularly.
b. Insertion of Intrajugular Catheter
-indicated for:
Central venous access for confusion of vasoactive drugs, TPN, high dose KCL, etc.
Hemorrhagic disorder where large volumes of blood or blood products needed.
Measurement of central venous pressure. Need for frequent blood draws where peripheral access
limited. Lack of peripheral access.
Contraindicated to:
Severe coagulopathy; the femoral or the IJ site is preferred with coagulopathy or anticoagulation due to the ability to compress the vein in the event of serious hemorrhage.
Infected skin site. In patients with higher risks for pneumothorax or
inability to tolerate pneumothorax, the IJ or femoral sites may also be preferred.
Nursing Responsibility:

-Assess the site for any signs of infection like swelling, redness
and fever.
-Avoid any procedure near the site.
c. Perm catheter- Insertion is the placement of a special IV line into the blood vessel in your neck or upper chest just under the collarbone.-This type of catheter is used for short-term dialysis treatment. ---The catheter is then threaded into the right side of your heart (right atrium). -The procedure involves creating a tunnel under the skin to thread the other portion of the catheter out through the skin. This tunneling process greatly reduces the risk of an infection and allows the catheter to remain in for a long period of time (one-12 months).
Nursing Responsibility:-Do not shower the day of your procedure or perform heavy activities such as lifting. Do not remove the dressing until you are instructed to do so.
-Will need to continue your routine dialysis treatments.
-Please inform your doctor of any fever or pain, redness or drainage at the catheter site.
-May have a small amount of bleeding at the site. Report any bleeding that continues or increases to your physician.
-May have mild pain for one to two days. May take whatever pain medications you use for minor aches and pains.
d. AV fistula
- An arteriovenous fistula (AV fistula) is the connection of a vein and an artery, usually in the forearm, to allow access to the vascular system for hemodialysis, a procedure that performs the functions of the kidneys in people whose kidneys have failed.
-the fistula develops over a period of months after the surgery.

- AV fistula provides a long-lasting site through which blood can be removed and returned during hemodialysis.
- allows the person to be connected to a dialysis machine.
Nursing Responsibility:
- Inform the client that the arm where the AVF should not be used for BP taking because the pressure exerted by the BP cuff may interfere with the blood flow and normal healing process of the anastomossed artery and vein.
e. Embolectomy
Embolectomy is the emergency surgical removal of emboli which are blocking blood circulation. It usually involves removal of thrombi (blood clots), and is then referred to as thrombectomy.
The removal of the clot with a catheter. The catheter, which is guided up from an artery in the groin to the site of the clot, deploys a special wire with loops in it. This wire threads through the embolus, gripping it so it can be pulled out.
Indications
Patients with pulmonary embolism (formed from
venous embolisms).
Used for patients with persisting shock despite
supportive care and who have an absolute
contraindication for thrombolytic therapy.
Nursing Responsibilities:
- Monitor vital signs of the patient.
