A nurse is preparing to administer duloxetine 120 mg PO once daily to a client. Available is duloxetine 40 mg capsules. How many capsules should the nurse administer? Round of the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Determine the desired dosage: The nurse needs to administer 120 mg of duloxetine. Determine the number of capsules per dose: Each capsule contains 40 mg of duloxetine. The nurse needs to administer 120 mg per dose. To find the number of capsules per dose: 40 mg / 1 capsule = 120 mg / x capsules Cross-multiplying gives us: 40x = 120 Dividing both sides by 40, we get: x = 3 capsules
