What is the recommended approach to weight-based drug dosing during pediatric resuscitation?

• A. Use fixed adult doses regardless of weight.
• B. Use weight-based calculations, verify doses, and document times and amounts.
• C. Use age-based dosing.
• D. Use body surface area-based dosing.

Answer: (B)

Weight-based dosing is essential in pediatric resuscitation because a child’s drug needs scale with body size, not age alone. Using steady per-kilogram calculations helps ensure the medication amount matches the child’s physiology, reducing the risk of overdose in smaller children or underdosing larger ones. In emergencies, you estimate the child’s weight quickly (with tools like a Broselow tape or length-based methods) and then calculate the dose as amount per kilogram multiplied by that weight. Before giving, verify the calculation and the drug concentration, and confirm the right route and timing. Immediately document the exact dose, time given, and the patient’s weight for every administration to maintain an accurate medication record and guide subsequent doses. Fixed adult doses are unsafe for kids, and age-based or body surface area–based approaches don’t provide the precision needed in resuscitation emergencies, making weight-based dosing with verification and documentation the best approach.
