Which tool is used to quickly estimate weight to guide dosing in pediatric emergencies?

• A. Broselow tape
• B. Age
• C. Height
• D. Head circumference

Answer: (A)

In pediatric emergencies, you need a quick, reliable way to estimate a child’s weight to calculate drug doses and select the right equipment. The Broselow tape does exactly that: you measure the child’s length and that color-coded tape provides an estimated weight along with ready-to-use dosing guidelines and equipment sizes. This lets clinicians choose mg/kg doses and appropriate devices without weighing the child, which can be impractical in an urgent situation. Weight-based dosing is essential because kids vary a lot in size for their age, making age-based estimates unreliable. Height alone isn’t a precise proxy for weight across ages, and head circumference isn’t used for dosing. So the Broselow tape is the best tool for quick weight estimation to guide dosing.
