Explanation:

Question 27

Antihypertensive drugs are used to lower blood pressure. Penicillin is an antibiotic used to treat bacterial infections, not for hypertension. Calcium channel blockers, cardiotonics (in some contexts related to heart function and blood pressure regulation), and diuretics are used in managing hypertension.

Coronary artery bypass surgery involves creating a detour (bypass) to supply blood to the heart muscle when coronary arteries are blocked by atherosclerosis. Cardiac tuning is not a recognized surgical term for this, venal bypass is for veins (not coronary arteries), and mitral commissurotomy is for the mitral valve, not for bypassing coronary arteries.

Answer:

penicillin
