Calculation
You have an order to give a child a dose of Ampicillin based on the child's body surface area. The child weighs 14 pounds. The normal adult dose is 1000 mg every 4-6 hours prn. The child's BSA is 0.45 m2. The Ampicillin is available as 250mg/5mL. How many mg would you administer to the child? Use the BSA method of calculation.
mg
Explanation & Rationale
Use the BSA (Body Surface Area) formula to calculate the child’s dose: Child's dose = BSA of child × (Adult dose ÷ 1.73) Child's dose = 0.45 × (1000 ÷ 1.73) Child's dose = 0.45 × 578.03 Child's dose ≈ 260.1 mg Round to a practical dose: 260 mg
