Correct Answer is A
Explanation
Choice A rationale
Nifedipine is a calcium channel blocker that is effective in treating hypertension and angina. It works by relaxing the blood vessels, which lowers blood pressure and improves blood flow to the heart, reducing chest pain and hypertension.
Choice B rationale
Digoxin is not typically used to treat hypertension. It is primarily used for heart failure and atrial fibrillation to increase the strength of heart muscle contractions and regulate heart rhythm.
Choice C rationale
Heparin is an anticoagulant used to prevent and treat blood clots. It does not directly treat hypertension or angina and is used for conditions like deep vein thrombosis, pulmonary embolism, and during surgeries to prevent clot formation.
Choice D rationale
Captopril is an ACE inhibitor used to treat hypertension and heart failure. While it is effective for lowering blood pressure, it is not primarily used for treating angina compared to medications like nifedipine or other calcium channel blockers.
Correct Answer is A
Explanation

Choice C rationale
Prochlorperazine (Compazine) is an anti-psychotic and anti-emetic medication used to treat nausea and vomiting, as well as certain mental/mood disorders.
