In the Rule of 9s, how much total surface area does each leg represent?

The correct answer is: 18%

In the Rule of 9s, each leg of an adult represents 18% of the total body surface area. This rule is used primarily to estimate the percentage of the body that is burned in order to guide treatment decisions, especially fluid resuscitation. When assessing burns, it is important to have a quick and effective method of estimating the affected area. The Rule of 9s breaks down the body into sections that each make up approximately 9% or a multiple thereof of the total body surface. For the legs, they are divided into two parts: each leg consists of 18% (9% for the front and 9% for the back). This method aids healthcare providers, especially in emergency settings, to make timely and effective treatment plans for burn victims.
