A client with hypertension complains of a persistent dry cough. The practical nurse (PN) should tell the client that this is a common side effect of which daily medication?

A. Quinapril: Quinapril is an angiotensin-converting enzyme (ACE) inhibitor. A persistent dry cough is a well-known side effect due to accumulation of bradykinin in the respiratory tract. Clients should be informed that the cough may resolve after discontinuation or switching to another antihypertensive class. B. Spironolactone: Spironolactone is a potassium-sparing diuretic and does not commonly cause a dry cough. Its primary side effects include hyperkalemia, gynecomastia, and menstrual irregularities rather than respiratory symptoms. C. Losartan: Losartan is an angiotensin II receptor blocker (ARB) and is less likely to cause a cough. It is often used as an alternative for clients who develop a cough with ACE inhibitors. D. Clonidine: Clonidine is an alpha-2 adrenergic agonist used for hypertension. Common side effects include sedation, dry mouth, and hypotension, but it does not typically produce a persistent dry cough.
