Answer to Question 1

ANS: C, D
Early clinical symptoms of left ventricular failure are decreased exercise tolerance and poor perfusion to peripheral tissues. Patients who develop left ventricular systolic failure as a result of MI have acute shortness of breath. Weight gain is more likely to be reported because of edema in diastolic failure. Patients who develop left ventricular systolic failure as a result of MI have shock with little peripheral edema and hypotension.

Answer to Question 2

ANS: A
Nausea and vomiting are serious adverse effects indicative of toxicity. Low potassium levels can cause toxicity; adequate intake of potassium is necessary. The dose is withheld if the pulse rate is less than 60 beats/min in adults. Visual disturbances are not common adverse effects.
