A nurse is preparing to administer ampicillin to a school-age child who weighs 55 lb. The provider prescribes 50 mg/kg/day in 4 equal doses. Available is ampicillin oral suspension 125 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: 12.5 mL

Rationale: 55 lb = 25 kg; 50 mg/kg/day = 1250 mg/day; 1250 mg / 4 doses = 312.5 mg/dose; 312.5 mg / (125 mg/5 mL) = 12.5 mL/dose.
