A nurse is preparing to administer hydroxyzine 1 mg/kg IM to a school-age child who weighs 67 lb. Available is hydroxyzine injection 25 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.)

First, convert the child's weight from pounds to kilograms: 67 lb / 2.205 lb/kg = 30.39 kg Calculate the total dose of hydroxyzine needed: 1 mg/kg * 30.39 kg = 30.39 mg Calculate the volume of hydroxyzine to administer: 30.39 mg / 25 mg/mL = 1.2156 mL Round to the nearest tenth: 1.2156 mL rounded to the nearest tenth is 1.2 mL.
