| Question | Answer |
| Digoxin: CLASSIFICATION | Cardiac Glycoside |
| Digoxin: ACTION | Inhibits sodium-potassium ATPase, promoting increased force of cardiac contraction, cardiac output, and tissue perfusioin; Decreases ventricular rate |
| Digoxin: USES/ THERAPEUTIC EFFECTS | To treat HF, Atrial Fibrillation |
| Digoxin: SIDE EFFECTS | Anorexia, nausea, vomiting, diarrhea, abdominal pain, headache, blurred vision, diploopia, photophobia, drowsiness, dizziness, fatigue, confusion |
| Digoxin: ADVERSE REACTIONS | Bradycardia, visual disturbances LIFE-THREATENING: Atrioventricular block, cardiac dysrhythmias |
| Digoxin: CONTRAINDICATIONS | Ventricular dysrhythmias, 2nd or 3rd degree heart block CAUTION: AMI, renal disease, hypothyroidism, hyperthyroidism, hepatic dysfunction, bradycardia, hypokalemia |
| Digoxin: INTERACTIONS | Decreased absorption with antacids, colestipol; Increased risk for toxicity with thiazide diuretics, loop diuretics |
| Digoxin: MONITOR | Lab: Hypokalemia, hypomagnesemia, hypercalcemia can increase toxicity |
| Digoxin: ASSESSMENT | -obtain a drug and herbal history -low serum potassium enhances action of digoxin -obtain baseline pulse rate (apical should be >60) -assess signs/symptoms of toxicity |
| Digoxin: INTERVENTIONS | -don't admin. if pulse <60 -determine peripheral/pulmonary edema (indicates HF) -serum digoxin level >2 = toxicity -monitor potassium level <3.5=hypokalemia |
| Digoxin: PATIENT TEACHING | -teach to check pulse rate -watch for herb-drug interaction -eat foods high in potassium |
