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.)

Answer and Explanation

The Correct Answer is ["12.5"]

To calculate the dosage, first convert the child's weight to kilograms (1 kg = 2.2 lbs), so 55 lbs is approximately 25 kg. The total daily dose of ampicillin prescribed is 50 mg/kg/day, which for a 25 kg child is 1250 mg/day (50 mg/kg * 25 kg). This total daily dose should be divided into 4 equal doses, resulting in 312.5 mg per dose (1250 mg/day ÷ 4 doses/day). The concentration of the ampicillin suspension is 125 mg/5 mL, so to find out how many mL per dose, divide the dose in mg by the concentration and multiply by the volume: 312.5 mg per dose ÷ 125 mg/5 mL = 2.5 * 5 mL = 12.5 mL per dose. Therefore, the nurse should administer 12.5 mL per dose.
