A nurse is admitting a client with severe burns. The nurse uses the rule of nines to estimate the percentage of total body surface area affected by burns. Which of the following statements accurately describes the rule of nines?

It divides the body into eight equal regions, with each region representing 12.5% of the total body surface area.

It divides the body into twelve equal regions, with each region representing 59% of the total body surface area.

It divides the body into six equal regions, with each region representing 15% of the total body surface area.

It divides the body into nine equal regions, with each region representing 100% of the total body surface area.

Answer and Explanation

The Correct Answer is A

A. It divides the body into eight equal regions, with each region representing 12.5% of the total body surface area:
The Rule of Nines assigns percentages to major body parts (e.g., each leg = 18%, each arm = 9%, anterior torso = 18%) totaling 100%.

B. It divides the body into twelve equal regions, with each region representing 59% of the total body surface area:
Incorrect math and region count; total exceeds 100% and is not part of the rule of nines.

C. It divides the body into six equal regions, with each region representing 15% of the total body surface area:
Also incorrect; not consistent with the actual anatomic distribution used in the rule of nines.

D. It divides the body into nine equal regions, with each region representing 100% of the total body surface area:
Nonsensical; if each is 100%, total would be 900%, which is not accurate.

Correct Answer is C

Explanation

A. Bright-red, moist lesions:
This describes superficial partial-thickness burns, not full-thickness burns.

B. Blackened, painful lesions:
Full-thickness burns may appear black (eschar), but they are typically painless due to nerve destruction.

C. Snowy white, painless lesions:
Full-thickness burns can be white, leathery, or charred and are often painless due to complete nerve damage.

D. Blistered, pinkish-white, painful lesions:
These are characteristic of deep partial-thickness burns, which retain some nerve sensation.

A. Administering pain medication B. Providing emotional support to the client C. Applying a topical burn ointment D. Assessing the client's airway and breathing

Correct Answer is D

Explanation

A. Administering pain medication
Pain control is important but secondary to ensuring the airway is clear.

B. Providing emotional support to the client
While necessary, emotional support is not an immediate priority during the acute phase of burn care.

C. Applying a topical burn ointment
This is appropriate after stabilization, not before airway and breathing are assessed.

D. Assessing the client's airway and breathing
Airway and breathing take top priority in burn clients, especially if the burns involve the face, neck, or chest. Inhalation injury, edema, or airway obstruction can be life-threatening and must be assessed immediately.
