Question

According to the “Rule of Nine” the head and neck area covers :

• A. 4.5%
• B. 9%
• C. 18%
• D. 21%

Hint:

Rule of 9: Head & Neck = 9%, each arm = 9%, each leg = 18%.

Answer 1

The Correct Option is B

Concept: The “Rule of Nines” is a method used in forensic medicine and emergency care to estimate the total body surface area (TBSA) affected by burns.

Step 1: Understanding the Rule of Nines.
The body is divided into sections, each representing a percentage of total surface area:
• Head and neck = 9%
• Each upper limb = 9%
• Each lower limb = 18%
• Anterior trunk = 18%
• Posterior trunk = 18%
• Perineum = 1%

Step 2: Applying to the question.
The head and neck together account for 9% of total body surface area.

Step 3: Final evaluation.
Thus, the correct value is 9%. Final Conclusion:
Hence, the correct answer is option (2).
