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.

Correct Answer is B

Explanation

A. Rubella is a contagious viral infection, and clients with different infectious diseases should generally be kept separate to prevent cross-infection.

B. Herpes zoster (shingles) is caused by the varicella-zoster virus. A client who has had varicella (chickenpox) would be immune to the virus and thus at low risk for contracting shingles from the roommate.

D. Tuberculosis is an airborne infection, requiring isolation precautions that would not make this pairing appropriate.
