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?

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. Choice D reason: Four tablets would equal 1,000 mg, which is double the prescribed dose and could be toxic.
