Answer to Question 1

ANS: A
Dysrhythmias are the most serious adverse effect of digoxin. Patients should be monitored frequently for changes in heart rate (bradycardia) and rhythm (A-V conduction problems).
A heart murmur is not an indication of digoxin toxicity, nor is a slow respiratory rate.
Bradycardia is a more accurate indication of digoxin toxicity than tachycardia.

Answer to Question 2

ANS: C
The first-line therapy for heart failure now consists of three drugs: a diuretic, an ACE inhibitor or angiotensin-receptor blocker (ARB), and a beta blocker.
The other regimens listed are not considered first-line therapy for heart failure.
