What formula is used for calculating Body Surface Area (BSA)?

The formula for calculating Body Surface Area (BSA) is based on the relationship between an individual's weight and height, which reflects the surface area of the body. The correct option provides a calculation that utilizes both the weight and height to derive the BSA in square meters.

This formula incorporates an exponent for weight raised to the power of 0.425 and height raised to the power of 0.725, making it a valid choice as it appropriately reflects the geometric scaling of body dimensions. The constant 0.007184 is a normalization factor that converts the result into square meters, ensuring the output is in the correct units for medical assessments.

Using this formula allows healthcare professionals to estimate the metabolic mass and assist in dose calculations for various medical treatments, particularly in the fields of oncology and other specialties where drug dosing tailored to BSA is critical.

Other options do not correctly represent the established method for calculating BSA. For instance, dividing height by an exponent or simply summing weight and height does not yield a meaningful or accurate representation of body surface area.
