A prescription for rifampin 300 mg is to be administered in two divided doses with available tablets of 150 mg. How many tablets will be given per dose?

To determine how many tablets of rifampin should be given per dose, first, consider the total daily dosage required. The prescription indicates that 300 mg is to be administered in two divided doses. This means that the total dosage of 300 mg will be split into two equal parts.

When divided, each dose will be 150 mg (300 mg ÷ 2 = 150 mg). With the available tablet strength being 150 mg, it is clear that one tablet of rifampin will satisfy the required dose of 150 mg per administration.

Thus, for each dose, one tablet is needed to meet the prescribed 150 mg dosage, making it clear that the correct answer reflects this calculation efficiently.
