How should pediatric dosing accuracy be supported preoperatively?

• A. Use weight-based dosing and confirm weight and age; double-check medication calculations
• B. Use fixed adult dosing
• C. Rely on prescription history alone
• D. Use age-based dosing only

Answer: (A)

Dosing in children is guided by body size, because children vary widely in weight and organ maturity, which directly affects how drugs are distributed and cleared. Using weight-based dosing (mg per kg) tailors the amount to the individual child rather than applying a one-size-fits-all amount. To ensure accuracy, you must confirm the child’s weight and age, since both factors influence the correct dose and the concentration of preparation to use. Calculations should be double-checked or reviewed by a second clinician or pharmacist to catch arithmetic errors, which are common and can lead to dangerous underdosing or overdosing. This approach accounts for rapid growth and variability among pediatric patients, making it safer than fixed adult dosing, which would likely deliver too much medication to small children. Relying solely on prescription history ignores the child’s current weight and needs, and using age-based dosing alone can be inaccurate due to weight variations within the same age group.
