A nurse is preparing to administer fluoxetine 40 mg PO daily. The amount available is fluoxetine 20 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step 1: Identify the dosage required and the concentration available. Required dosage: 40 mg Available concentration: 20 mg/mL Step 2: Calculate the volume to be administered. Volume to be administered = Required dosage ÷ Available concentration Volume to be administered = 40 mg ÷ 20 mg/mL Step 3: Perform the division. Volume to be administered = 40 ÷ 20 Volume to be administered = 2 mL Step 4: Round the answer to the nearest whole number (if necessary). Volume to be administered = 2 mL (no rounding needed) The nurse should administer 2 mL.
