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.)

The correct answer is 2 capsules per dose. To calculate this, we first convert the total daily dose of 2 grams to milligrams (2000 mg). Then divide the total daily dose by the number of doses per day (4 doses), resulting in 500 mg per dose. Since each capsule is 250 mg, the nurse should administer 2 capsules per dose to achieve the required 500 mg. Other choices are incorrect because they do not follow the correct calculation process or do not result in the required dosage of 500 mg per dose.
