A nurse is preparing to administer nifedipine 20 mg PO three times a day. Available is nifedipine 10 mg capsules. How many capsules should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Determine the desired dosage per dose: The client is prescribed 20 mg of nifedipine three times a day. The dosage per dose is 20 mg. Determine the number of capsules per dose: Each capsule contains 10 mg of nifedipine. The nurse needs to administer 20 mg per dose. To find the number of capsules per dose: 10 mg / 1 capsule = 20 mg / x capsules Cross-multiplying gives us: 10x = 20 Dividing both sides by 10, we get: x = 2 capsules
