A

Both are 18% each (total of 36% for entire trunk including anterior & posterior surfaces)

20
Q

Rule of 9’s: Arms account for what percent?

A

Each arm is worth 9% total (front= 4.5%; back=4.5%)

Bilateral front/back of arms=9%

Bilateral arms, front and back= 18%

21
Q

Rule of 9’s: legs make up what percentage?

A

Each leg is 18% total (9% front; 9% back)

Bilateral front/ back of legs = 18%

Bilateral legs, front and back= 36%

22
Q

How do the child (under 1 year of age) values for burns differ from the adult values? How is it adjusted each year after? At what age do adult values apply?

A

Under 1 year of age: 9% is taken from the lower extremities and added to head & neck (LE= 9% (4.5% front/ back) and neck/ head=18%)

Each year of life 1% is distributed back to the lower extremities (ex. Age 4 LE: 9% + 1%(3 years)= 12% for each LE (6% front, 6% back)

Adult values apply at age 9
