Verified step by step guidance

Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. In the context of burns, the body needs to regulate temperature, fluid balance, and energy needs.

Recognize the impact of burns on the body: Burns can disrupt homeostasis by causing fluid loss, increased metabolic demands, and potential infection risks. The severity of these effects often correlates with the extent of the body surface area affected.

Learn about the Rule of Nines: This is a method used to estimate the total body surface area affected by burns. It divides the body into sections, each representing approximately 9% of the total surface area, helping to quickly assess the extent of burns.

Consider the threshold for nutritional support: When burns cover a significant portion of the body, such as 20% or more, the body's nutritional and metabolic needs increase substantially, necessitating nutritional support to aid recovery and maintain homeostasis.

Evaluate the options given: Compare the percentages provided (5%, 10%, 20%, 30%) with the understanding that nutritional support is typically needed when burns cover 20% or more of the total body surface area, as this is when the body's demands significantly increase.
