A nurse is preparing to administer vancomycin 500 mg PO daily divided into four equal doses. The amount available is vancomycin 125 mg capsules. How many capsules should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The nurse should administer 1 capsule with each dose.

Explanation:
500 mg / 4 doses = 125 mg per dose
Each capsule is 125 mg, so the nurse should administer 1 capsule with each dose.
