Percentage of surface area of palm of a burn patient: FMGE 10; AI 11

**Core Concept:** The burn percentage of surface area (% TBSA) is a method to quantify the extent of burn injury. The three categories of burn size classification are:

1. **Small Burns (1-29% TBSA):** These burns are generally localized and can heal without surgical intervention.
2. **Moderate Burns (30-49% TBSA):** These burns require active management, including debridement and skin grafting.
3. **Large Burns (50% and above TBSA):** These burns are severe and require intensive care unit (ICU) management, including mechanical ventilation, vasopressor support, and organ function monitoring.

**Why the Correct Answer is Right:** The correct answer is **C. 10% TBSA**, as it represents the smallest burn category. A burn covering 10% TBSA or less is considered a small burn and can be managed without surgical intervention. In this case, the palm of a burn patient contributes to the total surface area calculation.

**Why Each Wrong Option is Incorrect:**

A. **11% TBSA (AI):** This option is wrong because it exceeds the upper limit of a small burn (10% TBSA). A burn covering 11% TBSA or more is considered a moderate to severe burn, requiring surgical intervention and ICU management.

B. **FMGE 10%:** This option is incorrect because it only considers the FMGE category, which is not the total surface area of the palm. To determine the burn percentage, we need to calculate the total surface area of the palm and compare it to the total body surface area (TBSA) percentages.

D. **Undefined:** This option is irrelevant because it does not provide a specific value for the burn percentage. To evaluate the severity of a burn, we need to consider the percentage of TBSA involved.

**Clinical Pearl:** When assessing burn patients, it is essential to consider the total body surface area percentage involved to guide appropriate treatment and resource allocation. A small burn (1-29% TBSA) can be managed conservatively, while moderate burns (30-49% TBSA) require surgical intervention and intensive care unit management. Burns involving 50% TBSA or more are considered severe and pose significant risk to the patient's life.
