Magnesium oxide 1200 mg PO daily, to be divided into three equal doses, is prescribed for the client. Each capsule contains 400 mg. How many capsules should the nurse administer with each dose? (Enter numeric value only.)

Calculation: Calculate the amount of medication to administer with each dose. Dose per administration (mg) = Total daily dose (mg) / Number of doses per day = 1200 mg / 3 doses = 400 mg/dose. Available strength = 400 mg/capsule. Calculate the number of capsules to administer with each dose. Number of capsules = Dose per administration (mg) / Available strength (mg/capsule) = 400 mg / 400 mg/capsule = 1 capsule.
