A nurse is preparing to administer methy prednisolone 7 mg/kg/day IM in two divided doses to a school-age child who weighs 64 lb. Available is methyiprednisolone 20 mg/mL. How many mL 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.)

First, convert the child's weight from pounds to kilograms: 64 lb / 2.205 lb/kg = 29.02 kg Calculate the total daily dose of methylprednisolone needed: 7 mg/kg x 29.02 kg = 203.14 mg Calculate the dose per administration: 203.14 mg / 2 = 101.57 mg Calculate the volume of methylprednisolone to administer per dose: 101.57 mg / 20 mg/mL = 5.0785 mL Round to the nearest tenth: 5.0785 mL rounded to the nearest tenth is 5.1 mL.
