Final answer:
The estimated percentage of burned skin can be calculated using the Rule of Nines. In this case, the head and neck, anterior trunk, and left upper extremity are all affected. The total estimated percentage of burned skin would be 36%.
Step-by-step explanation:
The estimated percentage of burned skin can be calculated using the Rule of Nines, a method used to determine the extent of burns on the body. According to this rule, the head and neck make up 9% of the body surface area, the anterior trunk (front of the torso) accounts for 18%, and each upper limb (LUE = left upper extremity) represents 9%. Therefore, if an adult patient sustained burns on the head and neck, the anterior trunk, and the entire left upper extremity, the estimated percentage of burned skin would be:
- Head and neck: 9%
- Anterior trunk: 18%
- Left upper extremity: 9%
To calculate the total percentage of burned skin, you simply add up these percentages:
Total percentage of burned skin = 9% (head and neck) + 18% (anterior trunk) + 9% (left upper extremity) = 36%
