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 A
Explanation
Choice A reason: Untreated hypothyroidism progresses to myxedema, a severe state with slowed metabolism causing fatigue, cold intolerance, constipation, and hair loss from low thyroid hormone.
Choice B reason: Hypocalcemia results from hypoparathyroidism, not hypothyroidism, which affects metabolism, not calcium regulation directly, so it’s unrelated to these symptoms.
Choice C reason: Pericarditis may occur in severe hypothyroidism late, but it’s not the primary complication; myxedema encompasses the broader metabolic decline seen here.
Choice D reason: Thyroid crisis (storm) is a hyperthyroid emergency with fever and tachycardia, opposite to hypothyroidism’s slow symptoms like coldness and fatigue.
Correct Answer is A
Explanation
Choice A reason: Gamma globulins (IVIG) provide antibodies to fight infections and stabilize platelet and RBC counts in lupus by modulating immunity, addressing cytopenias effectively.
Choice B reason: Prednisone suppresses immunity, reducing lupus inflammation but lowering infection resistance and not directly boosting platelets or RBCs, risking suppression.
Choice C reason: Methotrexate inhibits folate, suppressing lupus immune activity, but it can reduce blood cell production, not increase platelets or RBCs, worsening counts.
Choice D reason: Hydroxychloroquine prevents lupus flares by stabilizing lysosomes, not boosting blood counts or immunity, focusing on symptom control, not cytopenias.
