Understanding the Rule of Nines for Burns

The video explains the Rule of Nines, a method used to estimate the total body surface area affected by burns. It details the percentage of body surface area for different parts: head and neck (9%), each arm (9%), each leg (18%), trunk (36%), and groin (1%). The rule applies only to partial and full thickness burns, not superficial burns. An example is given for calculating the affected area of a burn on an arm. Additional resources are available for further study.

What is the primary purpose of the Rule of Nines?

• To estimate the total body surface area affected by burns

• To assess the need for hospitalization

• To determine the type of burn

• To calculate the severity of a burn

Which body part accounts for 9% of the total body surface area according to the Rule of Nines?

• The groin

• The entire trunk

• The right leg

• The head and neck

How much of the total body surface area do both legs together account for?

• 18%

• 9%

• 36%

• 27%

For which types of burns is the Rule of Nines applicable?

• First degree burns

• Second and third degree burns

• All types of burns

• Chemical burns only

If a patient has burns on the entire anterior right arm, what percentage of the body surface area is affected?

• 18%

• 9%

• 1%

• 4.5%

Which of the following is NOT included in the Rule of Nines?

• Third degree burns

• Full thickness burns

• Superficial burns
