The total daily dosage of a medication for a client is 4,000 mg to be administered in two equal doses. The medication is available in 0.5 gm tablets. How many tablets should be given for each dose?

• A. 2
• B. 4
• C. 6
• D. 8

Answer: (B)

To figure out how many tablets to give per dose, first determine the amount needed for each administration. The total daily dose is 4,000 mg, split into two equal doses, so each dose is 2,000 mg. Each tablet provides 0.5 g, which is 500 mg. Divide the dose per administration by the tablet strength: 2,000 mg ÷ 500 mg per tablet = 4 tablets per dose. A quick check confirms the daily total: 4 tablets per dose × 2 doses = 8 tablets, and 8 × 500 mg = 4,000 mg.
