If a patient is prescribed 500 mg/day of Sertraline and the medication is available in 250 mg tablets, how many tablets should be administered each day?
3 tablets
2 tablets
1 tablet
4 tablets
The Correct Answer is B
Choice A reason: Three tablets would equal 750 mg, which exceeds the prescribed 500 mg dose and could lead to overdose.
Choice B reason: Two tablets of 250 mg each equal the prescribed 500 mg dose, making this the correct answer.
Choice C reason: One tablet would equal 250 mg, which is only half the prescribed daily dose and would be ineffective.

Correct Answer is A
Explanation
Choice A reason: Three tablets equal 150 mg, which is the total daily dose, not the per-dose amount.
Choice B reason: 300 mg divided into two doses equals 150 mg per dose. Each tablet is 50 mg, so 150 ÷ 50 = 3 tablets per dose. Wait correction → That equals 3 tablets per dose, not 5. The correct option should be A).
The correct answer is: A).
Choice A reason: Each dose must equal 150 mg. With 50 mg tablets, that equals 3 tablets per dose. This is the accurate calculation.
Choice B reason: Five tablets would equal 250 mg per dose, which is too high and exceeds the prescribed amount.
Choice C reason: Six tablets equal 300 mg per dose, doubling the total daily prescription.
Choice D reason: Four tablets equal 200 mg per dose, which is higher than prescribed.
Correct Answer is C
Explanation
Choice A reason: Pseudoparkinsonism involves tremors, shuffling gait, rigidity, and bradykinesia, but it does not cause high fever, blood pressure instability, or diaphoresis.
Choice B reason: Tardive dyskinesia involves involuntary movements such as lip smacking, tongue protrusion, or grimacing, and it develops gradually after long-term medication use. It does not cause acute systemic symptoms.
Choice C reason: Neuroleptic malignant syndrome (NMS) is a rare but life-threatening reaction to antipsychotics. It presents with hyperpyrexia, autonomic instability (blood pressure changes, diaphoresis), muscle rigidity, and altered mental status. This fits the scenario.
Choice D reason: Acute dystonia is characterized by sudden, severe muscle contractions (often of the neck, eyes, or jaw) but does not include fever or autonomic instability.
