A patient presents to the ER with numbness in the left arm, a severe headache, and trouble speaking. Which of the following diagnostic tests do you anticipate the healthcare provider to order?
CT scan
Hemoglobin and hematocrit
MRI
Pulmonary angiography
The Correct Answer is A
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: 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 D
Explanation
Choice A reason: Steak, a solid, requires chewing and swallowing coordination, risking aspiration in dysphagia post-CVA due to impaired pharyngeal muscle control.
Choice B reason: Iced tea, a thin liquid, flows quickly, increasing aspiration risk in CVA patients with weakened swallow reflexes, unable to manage thin consistencies safely.
Choice C reason: Grapes, small and round, pose choking and aspiration hazards in dysphagia, as they require intact bolus control, often compromised post-stroke.
Choice D reason: Mashed potatoes, soft and thick, are easier to swallow, reducing aspiration risk in dysphagia post-CVA, aligning with thickened consistency recommendations.
