A child weighing 55 pounds is receiving ampicillin 300 mg/kg/24 hours intravenously (IV) in equally divided doses every 4 hours. How many mg should the nurse administer to the child for each dose? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1","250"]
Convert weight: 55 pounds ÷ 2.2 = 25 kg
Total daily dose: 300 mg/kg × 25 kg = 7,500 mg
Dose per 4 hours: 7,500 mg ÷ 6 = 1,250 mg per dose

(mL/hour) x (drop factor) / 60 = drops/minute.
The drop factor for a microdrip chamber is commonly 60 drops/mL.
Prescribed rate of 45 mL/hour, the calculation would be: (45 mL/hour) x (60 drops/mL) / 60 minutes/hour = 45 drops/minute.
Correct Answer is ["300"]
Explanation
Infusion rate: 75 mL/hour Time: 8 hours
