Study Notes
- Digoxin (Lanoxin) nursing implications include monitoring apical heart rate for a full minute, blood pressure, lung sounds, respirations, intake and output, daily weights, and examining extremities for edema and neck for jugular vein distention.
- Nursing implications for digoxin administration emphasize taking the medication at the same time each day, oral preparation without regard to meals, avoiding antacids, monitoring potassium levels, and conducting periodic EKG, electrolyte, liver, and kidney function tests.
- Positive outcomes of administering phosphodiesterase inhibitors include decreased urine output, weight, edema, shortness of breath, and fatigue relief, as they exhibit positive inotropic activity and vasodilating properties in short-term heart failure management when digoxin is ineffective.
- Anti-arrhythmic drugs like quinidine, disopyramide, lidocaine, mexiletine, phenytoin, flecainide, and propafenone are categorized into classes I-A, I-B, I-C, and II based on their mechanisms of action and indications for treating various types of arrhythmias.
- Beta blockers such as propranolol and acebutolol are used to manage supraventricular tachycardia and ventricular arrhythmias by reducing sympathetic excitation in the heart and blocking beta receptors, with common adverse effects on different body systems.
- Class III anti-arrhythmics like amiodarone are potassium channel blockers that lengthen action potential in myocardial cells to treat ventricular arrhythmias effectively.
- Class IV drugs like verapamil and diltiazem are calcium channel blockers that block calcium uptake by myocardial cells to manage various cardiac arrhythmias, with potential adverse effects on different body systems.
- Cardiotonics, also known as cardiac glycosides or digitalis glycosides, enhance calcium movement into myocardial cells to increase cardiac output through positive inotropic activity and decrease conduction velocity through SA and AV nodes, commonly used in heart failure, atrial fibrillation, flutter, and supraventricular tachycardia.
