A nurse is caring for a client who is taking lisinopril. Which of the following outcomes indicates a therapeutic effect of the medication?

A. Lisinopril is an ACE inhibitor, which is not intended to increase HDL (high-density lipoprotein) cholesterol levels. It works to decrease blood pressure and help with heart failure, not to alter cholesterol levels directly. B. Lisinopril is not used for managing bipolar disorder, and its use does not prevent manic episodes. This medication's primary function is to treat high blood pressure and heart failure. C. Lisinopril does not directly affect sexual function. Any improvement in sexual function would be coincidental rather than a therapeutic effect. D. The primary therapeutic effect of lisinopril is a decrease in blood pressure. It works by inhibiting the angiotensin-converting enzyme, which relaxes blood vessels and lowers blood pressure.
