Gerontology Gerontology: Study of all aspects
of aging and its consequences Ageism: when older adults are
stereotyped
Gerontologic nursing: specialized nursing with knowledge of illness and health of the aging
AGEISM What are some stereotypic
characteristics of the elderly that you have heard? Or believe?
Dependent ?Frail ?Poor ?Lonely ?Unreliable d/t memory loss ?Rigid; narrow-minded ?Unable to learn ?
Older Adult Young Old 60-74 Middle Old 75-84 Old Old 85 &
older
Presently: 12.8% of population
2030: will increase to 20% of population
Biological Theories of Aging
Programmed Aging theory- genetics and heredity responsible for how an individual ages
Cross-Linkage Theory- deterioration of organs/cells causing decreased mobility
Somatic Mutation Theory- DNA changes result in physical decline
Stress Theory-causes structural & chemical changes thru the lifespan
Theories of Aging Most experts believe that a
combination of genetic and stochastic (random) events are responsible for aging.
Any single limited theory is insufficient.
Psychosocial Theories of Aging
Disengagement Theory- withdrawn, introspective, self-focused – Older theory; not widely accepted.
Continuity theory-characteristics, values remain constant thru life… repeat behaviors that brought success in the past
Activity Theory- satisfaction depends on involvement in new interests /activities or maintenance of high levels of functioning.
Psychosocial Theories of Aging
Erikson - ego integrity vs despairLife review or reminiscenceAcceptance and happiness with past life
Havighurst - maintenance of social contacts & relationships… be flexible & adaptSuccessful aging = ability to adapt to the changes associated with aging.
Cognitive Changes Ability to perceive and
understand one’s world Mild short term memory
loss Long term memory
remains intact Slower responses and
reactions
What does it mean to “grow old gracefully”
“Grow old along with me! The best is yet to be. The last of life, for which the first was made”. - Browning
“Even the oldest tree some fruit may bear:And as the evening twilight fades away, the sky is filled with stars, invisible by day”. - Henry Wadsworth Longfellow
Cognitive Changes – Abnormal Aging
Confusion Alzheimer’s disease Sundowning syndrome The 3 D’s: 1. Dementia Severe cognitive loss &
memory loss
2. Depression 3. Delirium
Theories about Sundowning
Possible Causes for increasing confusion: Person can’t see well in dimming light Hormone imbalances r/t biological clock Person tired @ end of day; decreased
coping Restlessness because daytime activities
are decreasing Caregivers communicate their own
fatigue & stress to clients
General Physiological Changes
All systems decline in overall functioning
Decreased physiological reserves Modified pace & more frequent rest
periods
Integumentary Changes Decreased skin
elasticity-wrinkling Increased dryness Thickened nails Thinning of hair
(baldness) Decreased SQ fat
Musculoskeletal Changes Stiff joints & less
flexibility Mobility slows &
posture stoops Muscle mass, tone
& strength decrease
Bone demineralization
Neurological Changes CNS responds
slower Rate of reflex
response decreases Sense of balance
declines Night sleep shortens Temp. regulation &
pain perception less efficient
Special Senses Changes Diminished
vision Night blindness Diminished
hearing Decreased
taste & smell
Cardiopulmonary Changes Blood vessels less
elastic Fatty plaque deposits
occur Cardiac reserve
decreases Less efficient lung
clearing Increased resp. rate,
diminished depth
Gastrointestinal Changes Digestive juices &
nutrient absorption decrease
Malnutrition & anemia common
Decreased peristalsis resulting in constipation & indigestion
Decreased insulin and thyroid production
Dentition Changes Tooth decay
continues
Missing teeth or ill fitting dentures effect eating habits
Genitourinary Renal blood flow decreases Waste products excreted more slowly Fluid/Electrolyte balance is fragile Bladder capacity decreases 50% Hypertrophy of prostate gland Atrophy, decreased secretions & thinning
of female genital tract Decreased estrogen and testosterone
levels
Adjusting to Changes of Aging Rest more Curtail driving Cane/walker
for mobility Diet/nutritional
changes Ageism
Adjusting – Older Adult is making many psychosocial adjustments
Retirement Reduced income Spouse’s health Social roles Living arrangements Role reversal
Common health problems Heart disease,
cancer, stroke Poly-Pharmacy Accidents, falls Arthritis Chronic illness Elder Abuse
Elder Abuse Any deliberate action or
negligence that harms elderly individuals:-physical-sexual-psychological-emotional-financial
Role of the Nurse in Promoting Health: Teaching Nutrition Exercise Immunizations Annual Physicals Medications
Nursing Dx Risk for loneliness Altered dentition Risk for falls Knowledge deficit Confusion Sexual dysfunction Wandering
Summary Nurses have to provide care to an
increasing geriatric population. Geriatric patients have specific
needs due to physiological and cognitive changes.
Nursing care needs to be tailored to the those needs.
