What is the rule of nines used for?

The size of a burn can be quickly estimated by using the “rule of nines.” This method divides the body’s surface area into percentages. The front and back of the head and neck equal 9% of the body’s surface area. The front and back of each arm and hand equal 9% of the body’s surface area.

How can you tell what degree a burn is?

There are three levels of burns:

1. First-degree burns affect only the outer layer of the skin. They cause pain, redness, and swelling.
2. Second-degree burns affect both the outer and underlying layer of skin. They cause pain, redness, swelling, and blistering.
3. Third-degree burns affect the deep layers of skin.

What percentage of the body is burned if a 16 year old male burned his back the back of his left leg and his entire right arm?

You can solve this question using “rule of nine” to calculate the area of the body. Each arm equals to 4.5% so entire arms would be 4.5%. Each side of body trunk equal to 18%, so entire back would be 18%. Each leg equal to 18%, back of the leg would be half of it so it will be 9%.
