A patient needs 300 mg of a medication where each tablet contains 150 mg. How many tablets should the nurse administer?

To determine how many tablets the patient needs, start by identifying the total amount of medication required, which is 300 mg. Each tablet contains 150 mg of the medication. To find out how many tablets are necessary, divide the total dose needed (300 mg) by the amount contained in one tablet (150 mg).

300 mg ÷ 150 mg per tablet = 2 tablets.

This calculation shows that the patient requires 2 tablets to achieve the desired dosage of 300 mg. Therefore, administering 2 tablets is correct as it ensures that the patient receives the full amount of medication needed.
