Which of the following medications would be appropriate for heart failure treatment?
Diphenhydramine
Epinephrine
Propylthiouracil (PTU)
Furosemide
The Correct Answer is D
Choice A reason: Diphenhydramine, an antihistamine, treats allergies or sleep issues by blocking histamine, not addressing heart failure’s fluid overload or cardiac dysfunction.
Choice B reason: Epinephrine boosts heart rate and pressure in emergencies like anaphylaxis, but it worsens heart failure by increasing cardiac workload, not reducing fluid.
Choice C reason: Propylthiouracil treats hyperthyroidism by inhibiting thyroid hormone, unrelated to heart failure’s need for fluid management or cardiac support.
Choice D reason: Furosemide, a loop diuretic, reduces fluid overload in heart failure by increasing urine output, relieving pulmonary edema and systemic congestion effectively.

Correct Answer is C
Explanation
Choice A reason: Radioactive iodine treats hyperthyroidism by destroying thyroid tissue, reducing hormone production. It’s contraindicated in hypothyroidism, where hormone replacement is needed instead.
Choice B reason: Sumatriptan, a serotonin agonist, treats migraines by constricting blood vessels. It has no role in hypothyroidism, which requires thyroid hormone supplementation.
Choice C reason: Levothyroxine replaces deficient thyroid hormone in hypothyroidism, normalizing metabolism by mimicking T4, addressing symptoms like fatigue and weight gain effectively.
Choice D reason: Levofloxacin, an antibiotic, fights bacterial infections but doesn’t address hypothyroidism’s hormonal deficiency, making it irrelevant to this condition’s treatment.
Correct Answer is ["A","B"]
Explanation
Choice A reason: Tachypnea occurs in left-sided heart failure as pulmonary edema from backpressure increases respiratory effort to oxygenate blood through fluid-filled alveoli.
Choice B reason: Cough in left-sided failure results from pulmonary congestion irritating airways, often producing frothy sputum as fluid leaks from capillaries into lungs.
Choice C reason: Jugular vein distention indicates right-sided heart failure, where systemic venous pressure rises, not left-sided, which affects lungs, not neck veins.
Choice D reason: Ascites, abdominal fluid buildup, stems from right-sided failure’s hepatic congestion, not left-sided failure’s pulmonary focus, making it unrelated here.
Choice E reason: Confusion may occur late in severe heart failure from hypoxia, but it’s not specific to left-sided failure’s early pulmonary symptoms like tachypnea.
