Which antihypertensive is associated with cough and hyperkalemia and is contraindicated in pregnancy?

• A. ACE inhibitors
• B. Beta-blockers
• C. Calcium channel blockers
• D. Diuretics

Answer: (A)

ACE inhibitors commonly cause a dry, persistent cough due to bradykinin buildup, and they can lead to hyperkalemia by decreasing aldosterone secretion. They are also contraindicated in pregnancy because they can cause fetal renal damage, oligohydramnios, and other fetal harms. The combination of cough and hyperkalemia is a classic clue pointing to this class, making it the best answer. Other antihypertensives don’t typically produce both a cough and hyperkalemia, nor carry the same level of fetal safety concerns.
