A patient requires a medication to be taken at a dose of 500 mg twice a day. If the medication is supplied in 250 mg tablets, how many tablets will be required per day?

• A. 1 tablet
• B. 2 tablets
• C. 3 tablets
• D. 4 tablets

Answer: (B)

To determine the number of tablets required per day, first, calculate the total daily dose that the patient needs. Since the patient is prescribed a dose of 500 mg to be taken twice a day, you multiply 500 mg by 2, which equals 1000 mg per day. Next, since the medication is supplied in 250 mg tablets, you need to figure out how many 250 mg tablets are needed to reach the total daily dose of 1000 mg. To do this, you divide the total daily dose by the strength of each tablet: 1000 mg (total daily dose) ÷ 250 mg (per tablet) = 4 tablets. Therefore, the patient will need 4 tablets per day to meet the prescribed dosage. This calculation aligns with the requirement of taking the medication as directed, ensuring effective treatment while adhering to dosing guidelines.
