A nurse is preparing to administer ketorolac 0.4 mg/kg IM to an adolescent who weighs 96.8 lb. The amount available is ketorolac 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Convert the adolescent's weight from pounds (lb) to kilograms (kg) using the conversion factor of 2.2 lb/kg. Patient's weight in kg = 96.8 lb / 2.2 lb/kg = 44 kg. Calculate the dose in milligrams (mg) for the adolescent. Dose (mg) = Ordered dose (mg/kg) × Patient's weight (kg) = 0.4 mg/kg × 44 kg = 17.6 mg. Available concentration = 15 mg/mL. Calculate the volume in milliliters (mL) to administer per dose. Volume (mL) = Dose (mg) / Available concentration (mg/mL) = 17.6 mg / 15 mg/mL = 1.1733 mL. Round the answer to the nearest tenth. = 1.2 mL.
