Answer to Question 1

ANS: C
The greatest risk with eplerenone is hyperkalemia, and combining this drug with a potassium-sparing diuretic creates a significant risk of hyperkalemia. Furosemide and enalapril, an ACE inhibitor, would not be contraindicated in this patient. Amlodipine and spironolactone would not cause hyperkalemia. The combination of metoprolol, a beta blocker, and furosemide would not be contraindicated in this patient.

Answer to Question 2

ANS: A
Dysgeusia is a relatively common side effect of ACE inhibitors. It is not necessary to withdraw the medication unless anorexia or weight loss occurs, so assessing the patient's weight is an appropriate nursing action. Unless the condition is interfering with the patient's weight, there is no need to withdraw the drug. Dysgeusia is not temporary. A WBC with differential is indicated if neutropenia, a rare side effect, is suspected.
