NUR 2502 Multidimensional Care III Final Exam – 100+ Q&As on Dysrhythmias, Pacemakers, Cardioversion & Valve Disorders

Comprehensive final exam review for MDC 3 covering ventricular fibrillation (defibrillation, CPR priority), pericarditis (chest pain, friction rub), mitral valve stenosis (diastolic murmur, rumbling), rheumatic fever (antibiotic prophylaxis before dental work), mechanical valves (endocarditis prevention, antibiotic teaching), aortic stenosis (balloon valvuloplasty), cardiomyopathy (diuretics, dependent edema monitoring), mitral valve prolapse (extra heart sound, mid-systolic click), infective endocarditis (lifelong antibiotic therapy, dental history), first-degree AV block (prolonged PR interval 0.20 sec), sinus bradycardia (atropine, symptomatic treatment), atrial flutter (sawtooth P waves, rate 250-400), atrial fibrillation (warfarin, anticoagulation, Maze procedure), asystole (CPR first, treat patient not monitor), pacemakers (capture, failure to capture, Twiddler syndrome, MRI contraindication, no arm above head for 2 weeks), ICD (log discharges, avoid contact sports), premature ventricular contractions (PVCs 6/min VT precursor, hypokalemia cause), Holter monitor (6-second strip count x10 = rate), and positive inotropic effect (increases myocardial contractility). Includes correct answers with rationales.
