A nurse is preparing to administer fluoxetine 30 mg PO for a client who has depression and cannot swallow capsules. Available is fluoxetine 20 mg/5 mL oral solution. How many mL should the nurse plan to administer? (Round to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is: 7.5 mL Step 1 is: Identify the prescribed dose = 30 mg. Step 2 is: Identify the available concentration = 20 mg per 5 mL. Step 3 is: Set up proportion. 20 mg ÷ 5 mL = 30 mg ÷ X mL. Step 4 is: Cross multiply. 20 × X = 30 × 5. 20X = 150. Step 5 is: Divide both sides. X = 150 ÷ 20 = 7.5. Step 6 is: Round to the nearest tenth. 7.5 = 7.5 mL (already at one decimal place). Final Answer: The nurse should administer 7.5 mL.
