Answer and Explanation

The Correct Answer is B

Step 1: Convert weight from lb to kg.

88 lb ÷ 2.2 = 40 kg

Step 2: Calculate total daily dose in mg.

150 mg/kg × 40 kg = 6000 mg

Step 3: Calculate dose per administration (every 6 hr).

6000 mg ÷ 4 = 1500 mg

Step 4: Calculate number of tablets per dose.

1500 mg ÷ 500 mg/tab = 3 tablets

Answer:

3 tablets per dose.
