A child weighs 6 lbs and is to receive Ampicillin 50 mg/kg/24 hrs and then it's divided into q hr doses. How many mg will he receive with each dose?

  • A. 90 mg
  • B. 60 mg
  • C. 36 mg
  • D. 290 mg
Correct Answer: C

Rationale: Step 1: Convert the child's weight from lbs to kg. Since 1 lb is approximately 0.45 kg, a child who weighs 6 lbs weighs approximately 2.72 kg (6 lbs × 0.45 =2.72 kg). Step 2: Calculate the total daily dose of Ampicillin. The total daily dose is 50 mg/kg/day, so for a child who weighs 2.72 kg, the total daily dose would be approximately 136 mg (50 mg/kg/day × 2.72 kg = 136 mg/day). Step 3: Since the total daily dose is divided into q hr doses (4 doses per day), each dose would be approximately 34 mg (136 mg/day ÷ 4 doses/day = 34 mg/dose). So, the child will receive approximately 34 mg of Ampicillin with each dose.
