Which unit is mandatory for weight-based pediatric dosing calculations?

• A. Kilograms (kg)
• B. Pounds (lb)
• C. Meters (m)
• D. Liters (L)

Answer: (A)

Weight-based pediatric dosing relies on the patient’s mass, so kilograms are the essential unit. Doses are typically expressed as mg per kilogram (mg/kg) or mcg/kg, meaning the calculation uses weight in kilograms to scale the amount of drug to the child’s size. Using kilograms keeps the dosing aligned with standard pediatric guidelines and minimizes errors that can come from converting between units. Pounds might be noted for a rough weight, but any accurate weight-based calculation should be done in kilograms after converting if needed. Meters measure height and aren’t used for weight-based dosing, and liters measure volume for fluids, not body mass.
