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

A. Decreased blood pressure: Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat high blood pressure (hypertension). A therapeutic effect of lisinopril is the lowering of blood pressure, which helps reduce the risk of cardiovascular events, such as stroke or heart attack. B. Improved sexual function: Lisinopril does not directly improve sexual function. While it may have fewer sexual side effects than other antihypertensive medications, it is not indicated for the improvement of sexual function. C. Increase of HDL cholesterol: Lisinopril does not significantly affect cholesterol levels. Its primary action is to lower blood pressure and improve heart function, particularly in heart failure, but it does not have a direct effect on increasing HDL cholesterol. D. Prevention of bipolar manic episodes: Lisinopril is not used to treat bipolar disorder or prevent manic episodes. Medications for bipolar disorder typically include mood stabilizers or antipsychotics, not antihypertensives like lisinopril.
