After starting an ACE inhibitor, which two monitoring parameters are most important?

• A. Heart rate and respiratory rate
• B. Liver enzymes and bilirubin
• C. White blood cell count and platelets
• D. Blood pressure and serum potassium

Answer: (D)

The main concept being tested is how ACE inhibitors affect the body after initiation and what must be watched closely for safety. ACE inhibitors cause vasodilation, which can lower blood pressure, and they can reduce aldosterone activity, leading to potassium retention. Because of these effects, the two most important things to monitor are blood pressure and serum potassium. Monitoring blood pressure helps detect excessive hypotension, especially after the first dose or with dose increases, so you can adjust the medication if the patient becomes lightheaded or systolic/diastolic pressures drop too much. Checking serum potassium is crucial to catch hyperkalemia early, which can cause dangerous heart rhythms if potassium levels rise too high. These two parameters guide dosing decisions and safety actions. Other options aren’t the primary safety concerns with ACE inhibitors: heart rate and respiratory rate are general vital signs but aren’t specifically targeted by these drugs; liver enzymes and bilirubin, or white blood cell count and platelets, aren’t the expected monitoring focus for ACE inhibitors.
