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.
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 ["B","C","D"]
Explanation
A. Cool the burn with ice water:
Never use ice on burns. It can cause vasoconstriction and worsen tissue injury.
B. Administer opioid analgesics:
Severe pain is common in burn injuries. IV opioids are preferred for rapid onset and titration.
C. Administer systemic antibiotics:
Burn injuries compromise the skin barrier, increasing the risk of infection. Systemic antibiotics may be necessary to prevent or treat infections.
D. Keep extremities elevated:
Elevating extremities helps reduce edema and improve venous return.
E. Remove all sheets and coverings:
Sheets may provide warmth and protection. Removing them indiscriminately may worsen hypothermia or cause further trauma to the skin.
