Pharmacology Study Guide Units 4-6

1. Digoxin Toxicity, adverse effect and things to monitor. Some adverse effects of Dig are anytypes of dysrhythmias, including bradycardia, tachycardia or hypotension. Headache, fatigue,

malaise, colored vision(green, yellow, or purple), halo vision, or flickering lights, anorexia,

nausea, vomiting and diarrhea. You need to monitor fluid and electrolyte levels, levels of

drugtherapeutic range is 0.8-2.0ng/ml.

2. Positive and Negative chronotropic and inotropic. Ionotropic drugs affect the force ofmyocardial contraction; positive inotropics (digoxin) increases the force of contractions and

negative inotropics (beta-blockers, calcium channel blockers) decrease myocardial contractility.

Chronotropics affect heart rate per minute, with positive chronotropic increases heart rate and

negative chronotropics decrease the heart rate.

3. Normal and therapeutic ranges for digoxin: normal therapeutic levels of Digoxin are between0.5 and 2 ng/ml. Higher than 2 are used to treat Afib. Theraputic on slide is 0.8-2.0ng/ml and

toxic is 2.2ng/ml. To reverse toxic effect use digoxin immune fab (Digibind) Listen for 1 full

minute for apical pulse, do not administer if less than 60.

at a time, do not apply to irritated skin, rotate sites, remove patch at betimes to allow 8 hr patch

free period.

7. Assessment findings with Nitrates: arterial vasodilator, used to treat angina, increases supply ofO2 and nutrients to the heart muscle, decrease blood return to the heart, decrease afterload.

8. Nitroglycerin tolerance: to avoid a tolerance to drug you must have an 8 hr nitrate free period.9. Adverse effects of Beta-blockers: bradycardia, hypotension, 2 or 3 degree heart block; heart

failure, altered glucose and lipid metabolism, dizziness, fatigue, mental depression, unusual

dreams, impotence, wheezing and Dyspnea.

10.Pt teaching for initial antihypertensive: (pg. 401) meds should be taken as ordered with nodoubling, maintain diet, avoid smoking, alcohol, saunas, hot tubs, keep up with follow-up

wk, sexual dysfunction can occur, do not discontinue medication abruptly, antihypertensives can

lead to depression.

11.Adverse affects of thrombolytic therapy: bleeding, nausea, vomiting, hypotension, anaphylacticreaction, and serious dysrhythmias. (Ch 26)

15.Goal of Anti-coagulant therapy: (pg. 449) increase comfort and relieve from pain, improve bloodflow, remain free from injury resulting from disease or meds, compliance of pt. regarding

lifestyle changes and medication regimen, pt demonstrates knowledge of med therapy and

potential adverse effects.

16.Pt. teaching Re: cholesterol med (power)(pg. 446): Powder should be dissolved for at least 1minute, needs to be taken 1 hr before or 4-6 hrs after meals. Never take as dry powder, take
