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: CT scan rapidly detects ischemic stroke or hemorrhage in the brain, critical for numbness, headache, and speech issues, guiding urgent treatment decisions.
Choice B reason: Hemoglobin and hematocrit assess blood count, not brain pathology like stroke, which requires imaging to identify infarction or bleeding, not anemia.
Choice C reason: MRI offers detailed stroke imaging but is slower than CT, less ideal for acute ER settings needing immediate diagnosis of neurological symptoms.
Choice D reason: Pulmonary angiography evaluates lung vessels for embolism, irrelevant to stroke symptoms (numbness, headache, speech difficulty), which localize to brain issues.
Correct Answer is D
Explanation
Choice A reason: Levothyroxine takes weeks to normalize metabolism in hypothyroidism as T4 converts to T3 gradually, so immediate symptom relief isn’t accurate or expected.
Choice B reason: Levothyroxine supplements, not decreases, thyroxine in hypothyroidism. Decreasing overproduction applies to hyperthyroidism treatments like antithyroid drugs, not this condition.
Choice C reason: Hypothyroidism requires lifelong levothyroxine since the thyroid can’t produce hormone. Stopping when symptoms resolve risks recurrence, making this advice incorrect.
Choice D reason: Excess levothyroxine mimics hyperthyroidism, causing tremors, nervousness, and insomnia from overstimulated metabolism, correctly indicating a need for dose adjustment.
