A nurse is caring for a client who is prescribed tetracycline 2 grams daily PO in four divided doses every 6 hr. Available is tetracycline 250 mg capsules. How many capsules should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the total daily dose from grams (g) to milligrams (mg). Total daily dose (mg) = 2 g x 1000 mg/g = 2000 mg. Calculate the dose to be administered per dose. The daily dose is divided into four equal doses. Dose per administration (mg) = 2000 mg / 4 doses = 500 mg. Calculate the number of capsules to administer per dose. Available strength = 250 mg/capsule. Number of capsules = Desired dose (mg) / Available strength (mg/capsule) = 500 mg / 250 mg/capsule = 2 capsules.
