Question 1 of 5

A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number.)

Correct Answer: A

Rationale:
To determine the mg per dose of erythromycin, first convert 2 g to mg (2000 mg). Since the dose is divided equally every 6 hours, divide 2000 mg by 4 (6 hr intervals in a day) to get 500 mg per dose.
Choice A (500 mg) is correct.

Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the total daily dose and dosing frequency.
