A nurse is reinforcing teaching with a client who is about to start taking captopril to treat hypertension. Which of the following instructions should the nurse include to help the client manage this medication's adverse effects?

A. Use salt substitutes while taking this medication: Salt substitutes often contain potassium, and captopril (an ACE inhibitor) can increase serum potassium levels, which raises the risk of hyperkalemia. B. Captopril should be taken 1 hour before or 2 hours after meals to ensure proper absorption and maintain optimal blood pressure control. C. Weight gain is not a typical side effect of captopril; instead, clients should monitor for signs of fluid retention or edema, which could indicate heart failure. D. Expect a dry cough when taking this medication: While a dry cough is a common side effect of captopril, clients should report it to their provider, as it may require switching to another antihypertensive (such as an ARB). It should not be presented as something to simply “expect and accept.”
