A nurse is preparing to administer indomethacin 75 mg PO bid. Available is indomethacin 25 mg/5mL. How many mL 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.)

Desired dose per administration = 75 mg. Available concentration = 25 mg/5 mL. Calculate the volume in milliliters (mL) to administer per dose. Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL)) = 75 mg / (25 mg / 5 mL) = 75 mg / 5 mg/mL = 15 mL.
