If a patient needs 500 mg of a medicine and you have 250 mg tablets, how many tablets should you give?

To determine the correct number of tablets required to administer 500 mg of medication when you have 250 mg tablets, you simply divide the total dose needed by the strength of each tablet.

In this scenario, you need to administer 500 mg. Each tablet contains 250 mg. When you divide 500 mg by 250 mg per tablet, you calculate how many tablets are necessary:

500 mg ÷ 250 mg/tablet = 2 tablets.

This calculation shows that you need 2 tablets to reach the total required dosage of 500 mg. Therefore, it is clear that administering 2 tablets is the appropriate choice to ensure the patient receives the correct amount of medication.
