A patient is prescribed 0.75 g of medication and the dosage available is in 250 mg tablets. How many tablets will the nurse administer?

To determine how many tablets of the medication the nurse should administer, it's important to first convert the prescribed dosage from grams to milligrams since the available medication is measured in milligrams.

The prescription is for 0.75 g. To convert grams to milligrams, you multiply by 1000, as there are 1000 milligrams in a gram:

0.75 g × 1000 mg/g = 750 mg.

Next, the prescribed dosage of 750 mg needs to be compared to the available dosage of the medication, which is 250 mg per tablet. To find out how many tablets are required to reach the prescribed amount of 750 mg, divide the total milligrams needed by the milligrams per tablet:

750 mg ÷ 250 mg/tablet = 3 tablets.

Therefore, the nurse will administer 3 tablets to meet the prescribed dosage of 0.75 g.
