A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Convert weight from pounds to kilograms: Child’s weight = 66 lb Conversion factor: 1 kg = 2.2 lb 66 lb ÷ 2.2 = 30 kg Calculate the total weekly dose: Prescribed dose = 0.24 mg/kg/week 30 kg × 0.24 mg/kg = 7.2 mg/week Determine the daily dose: The dose is given six times per week 7.2 mg ÷ 6 = 1.2 mg/day The nurse should administer 1.2 mg of somatropin per dose subcutaneously to the child.
