A patient is prescribed 150 mg/day of Lithium, divided into two equal doses. How much Lithium should be given per dose?
150 mg.
75 mg.
50 mg.
100 mg.
The Correct Answer is B
Choice A reason: Giving 150 mg in one dose would mean the full daily dose is administered at once, not divided as ordered.
Choice B reason: The total daily dose is 150 mg. Dividing this into two equal doses means 150 ÷ 2 = 75 mg per dose.
Choice C reason: Fifty mg per dose would only total 100 mg per day, which is below the prescribed dose.
Choice D reason: One hundred mg per dose would total 200 mg daily, which exceeds the prescribed 150 mg/day.
