The nurse is preparing to administer ampicillin PO to a 12-year-old child with impetigo who weighs 88 pounds. The prescription is for 50 mg/kg/day. How many mg should the child receive per day? (Enter numeric value only.)

Here's how to calculate the total milligrams of ampicillin the child should receive per day: Convert child's weight to kilograms: Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg) Weight (kg) = 88 lbs / 2.205 lbs/kg Weight (kg) = 40 kg (round to nearest whole number) Calculate the total daily dosage: Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg) Daily dosage (mg) = 50 mg/kg/day * 40 kg Daily dosage (mg) = 2000 mg Therefore, the child should receive 2000 mg of ampicillin per day.
