2. Carl Edwards is a 75-year-old man with congestive heart failure. Having sustained three myocardial infarctions in the last 10 years, he has decreased left ventricular function. Mr. Edwards takes Digoxin, Capoten, Coreg, and Lasix for management of this disease. Today he presents to the emergency department with fatigue, generalized weakness, and feelings of “skipping” heartbeats. Upon arrival, he is placed on the cardiac monitor, his vital signs are assessed, and an IV is inserted.

a.Which of his medications might be contributing to his symptoms of generalized weakness and heart irregularities?
b.For what clinical manifestations should you assess to correlate to his left-sided heart failure?
c.How do his medications treat his congestive heart failure?
d.How does the hypokalemia affect the effects of Digitalis?
