Q

Burn Classification and Severity (Cont.)

A patient has sustained second- and third-degree burns to the entire left arm and both legs anteriorly. Using the rule of nines, what is the percentage of body area with burn injury?
A. 18%
B. 21.5%
C. 24%
D. 27%

A

D. 27%

Rationale: Each arm is 4.5% for the anterior aspect and 4.5% for the posterior aspect. This patient’s entire arm is involved, thus 9% of body area is calculated. Each leg is 9% for the anterior aspect and 9% for the posterior aspect. The anterior aspects of both legs were involved with this patient, thus 18% of body area is calculated. Total percentage of body areas with burn injury is 27%.
