If a patient is to receive a dose of 1.5 grams and you have 500 mg tablets, how many tablets would you give?

To determine the correct number of tablets a patient would receive, it's essential to first convert the prescribed dose into the same unit of measurement as the available medication. The patient requires a dose of 1.5 grams. Since there are 1000 milligrams in a gram, 1.5 grams is equivalent to 1500 milligrams (1.5 g x 1000 mg/g = 1500 mg).

Next, since the medication is available in 500 mg tablets, you would divide the total required dose in milligrams by the amount in each tablet. Therefore, you would calculate:

1500 mg ÷ 500 mg/tablet = 3 tablets.

This calculation indicates that the patient should receive three 500 mg tablets to meet the prescribed 1.5-gram dose. The answer correctly reflects that three tablets are needed to achieve this dosage.
