Question

1. you are treating a 45 - year - old female patient who has partial - thickness burns totally covering her legs, chest, and abdomen. using the rule of nines, approxi - mate the size of the burn area.

a. 18%
b. 36%
c. 45%
d. 54%

Explanation:

Step1: Recall the rule of nines for adults

In the rule of nines for adults, the legs (each leg is 18%), chest (18%), and abdomen (9%).

Step2: Calculate the burn area

The patient has burns on both legs (18% + 18% = 36%), chest (18%), and abdomen (9%). So the total burn area is \(36\%+18\% + 9\%=63\%\) (This is wrong calculation). Wait, no, re - calculate: Legs (each 18% for entire leg, but if we consider front and back, but in the rule of nines for adults: Each entire leg is 18%, chest (anterior trunk) is 18% (front of trunk, which includes chest area in a sense as part of anterior trunk), abdomen is part of anterior trunk. Wait, no, the rule of nines: Anterior trunk (chest and abdomen) is 18%, each lower extremity (leg) is 18%. So for two legs \(18\%\times2 = 36\%\) and anterior trunk (chest + abdomen) is 18%. Total burn area \(36\%+18\%=54\%\)

Answer:

D. 54%
