Quizplus · Accepted Answer

The formula for estimating body surface area (BSA) is: BSA (m2) = 0.007184 * weight (kg)0.425 * height (cm)0.725. Converting the given height and weight to metric units: height = 4 feet * 0.3048 meters/foot = 1.2192 meters; weight = 85 pounds * 0.453592 kilograms/pound = 38.555 kilograms. Plugging these values into the formula: BSA (m2) = 0.007184 * 38.5550.425 * 1.21920.725 = 1.139 m2. Therefore, the estimated body surface area is 1.14 m2, which corresponds to choice D.
