Question

The medication order reads: niacin, 500 mg PO, every evening. The medication is available in 250-mg tablets. How many tablets will the patient receive per dose?

Answer 1

To fulfill a prescribed dose of 500 mg of niacin using 250-mg tablets, the patient will receive two tablets per dose.

Step-by-step explanation:

The question is concerning the administration of niacin, a medication prescribed at a dosage of 500 mg to be taken orally each evening. Given that the medication is available in 250-mg tablets, the calculation to determine the number of tablets per dose is straightforward. To administer 500 mg of niacin using 250-mg tablets, you would need two tablets:

1. Determine the total prescribed dosage: 500 mg.
2. Divide the total prescribed dosage by the strength of each available tablet: 500 mg ÷ 250 mg/tablet.
3. This gives us the result of 2, indicating that two 250-mg tablets are necessary to fulfill the 500 mg dosage.
