A patient is prescribed 1.2 g of a drug daily, available as 300 mg tablets. How many tablets are needed for a daily dose?

To determine how many 300 mg tablets are needed for a daily dose of 1.2 g, first, it is important to convert the grams into milligrams since the medication is provided in milligram dosage. There are 1000 milligrams in 1 gram, so:

1.2 g equals 1.2 x 1000 mg = 1200 mg.

Next, we need to figure out how many 300 mg tablets are required to reach the prescribed dose of 1200 mg. This is done by dividing the total daily dose in milligrams by the amount per tablet:

1200 mg ÷ 300 mg/tablet = 4 tablets.

Thus, the patient would need a total of 4 tablets to achieve the prescribed daily dose of 1.2 g. This calculation clearly demonstrates how to convert between grams and milligrams, as well as how to perform the division to find the required number of tablets to meet the prescribed dosage.
