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.)
The Correct Answer is ["12.5"]
To calculate the dose of ampicillin for a school-age child who weighs 55 lb, follow these steps: Convert the weight from pounds to kilograms:
55 lb × 1 kg/2.2 lb = 25 kg
Calculate the total daily dose of ampicillin:
50 mg/kg/day × 25 kg = 1250 mg/day
Divide the total daily dose by the number of doses per day:
1250 mg/day ÷ 4 doses/day = 312.5 mg/dose
Convert the dose from milligrams to milliliters using the concentration of the oral suspension:
312.5 mg/dose ÷ 125 mg/5 mL = 12.5 mL/dose
So, the nurse should administer approximately 12.5 mL of ampicillin oral suspension with each dose.
