According to the Rule of Nines, what is the TBSA for burns covering the right arm, hand, thigh, and lower leg?

The Rule of Nines is used to quickly estimate the total body surface area (TBSA) affected by burns in adults. According to this rule, different parts of the body represent specific percentages of the total body surface area.

For adults, the right arm is typically considered to account for 9% of TBSA, the hand contributes an additional 1%, the front of the right thigh represents 9%, and the front of the right lower leg accounts for 4.5%.

When calculating the TBSA for burns covering the right arm, hand, thigh, and lower leg, you would sum these percentages:

• Right arm: 9%
• Right hand: 1%
• Right thigh: 9%
• Right lower leg: 4.5%

When added together, the total equals 9% + 1% + 9% + 4.5% = 23.5%.

However, if the thigh and lower leg are considered as both front and back burns (which increases the total), the total TBSA may reach up to 27%. This adjustment takes into consideration the whole circumference or extent of the burn area, rather than just the front or back surface.

Therefore, selecting 27% as
