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.

A. Anaphylaxis. B. Insomnia. C. Motion sickness. D. Reduces effects of allergies, including sneezing, nasal itching, and runny nose.

Correct Answer is D

Explanation

Choice A rationale

Anaphylaxis is a severe, potentially life-threatening allergic reaction. Fluticasone is not used for treating anaphylaxis.

Choice B rationale

Insomnia is a sleep disorder. Fluticasone is not used for treating insomnia.

Choice C rationale

Motion sickness is a condition that occurs in response to certain kinds of movement. Fluticasone is not used for treating motion sickness.

Choice D rationale

Fluticasone (Flonase) is a corticosteroid used to reduce the effects of allergies, including sneezing, nasal itching, and runny nose. It works by reducing inflammation in the nasal passages.
