Which of the following medications are going to dilate the coronary arteries and redirect blood flow so that ischemic tissue is oxygenated?

Salmeterol

Aspirin

Digoxin

Nitroglycerin

Answer and Explanation

The Correct Answer is D

Choice A reason: Salmeterol, a long-acting bronchodilator, opens airways in asthma or COPD but doesn’t dilate coronary arteries or improve cardiac ischemia, targeting lungs instead.

Choice B reason: Aspirin prevents clotting by inhibiting platelet aggregation, reducing ischemia risk, but it doesn’t directly dilate coronary arteries or acutely redirect blood flow.

Choice C reason: Digoxin increases cardiac contractility in heart failure, improving output, but it doesn’t dilate coronary vessels or specifically oxygenate ischemic myocardium.

Choice D reason: Nitroglycerin, a vasodilator, relaxes coronary arteries, increasing blood flow to ischemic areas, relieving angina by enhancing oxygen delivery to the heart muscle.

Correct Answer is C

Explanation

Choice A reason: Hydroxychloroquine treats autoimmune diseases like lupus by modulating immunity, not hyperthyroidism’s excess thyroid hormone production, irrelevant here.

Choice B reason: Levothyroxine supplements thyroid hormone in hypothyroidism, worsening this patient’s hyperthyroidism (high T3/T4), contraindicated for her symptoms.

Choice C reason: Potassium iodide inhibits thyroid hormone release, reducing T3 and T4 in hyperthyroidism (e.g., Graves’), addressing her goiter, exophthalmos, and weight loss effectively.

Choice D reason: Methotrexate suppresses immunity in cancer or autoimmunity, not targeting thyroid overactivity or hormone levels, unsuitable for hyperthyroidism management.

A. Fluticasone B. Captopril C. Carvedilol D. Isosorbide dinitrate

Correct Answer is C

Explanation

Choice A reason: Fluticasone, an inhaled steroid, treats asthma inflammation safely in heart failure, reducing airway reactivity without cardiac impact, so no clarification is needed.

Choice B reason: Captopril, an ACE inhibitor, reduces preload in heart failure, safe with asthma as it doesn’t affect airways, aligning with standard therapy.

Choice C reason: Carvedilol, a non-selective beta-blocker, treats heart failure but risks bronchospasm in asthma by blocking beta-2 receptors, requiring clarification for safety.

Choice D reason: Isosorbide dinitrate dilates vessels in heart failure, reducing workload, with no asthma contraindication, making it appropriate without needing clarification.
