An adult client experiences a gasoline tank fire when riding a motorcycle and is admitted to the emergency department (ED with full thickness burns to all surfaces of both lower extremities. Which percentage of body surface area should the nurse document in the electronic medical record (EMR)?

A. 18%: This would be the correct percentage for one leg only. B. 36%: According to the Rule of Nines in burn assessment, each leg (including the foot) accounts for 18% of the body surface area. Since both lower extremities are affected, it totals 36% body surface area. C. 4%: This percentage is too low for the described injury. D. 09%: This would not be enough even for one leg, as each leg is 18%.
