Final answer:
Hypermetabolism after major burns is due to increased heat loss, demand for tissue repair, and a recurrent stress response; therefore, the correct answer is e. a, b, c.
Step-by-step explanation:
Hypermetabolism is common with major burns due to several factors. The primary reasons are:
- Increased heat loss from the burn wound, as the skin is no longer able to retain heat efficiently.
- The demand for tissue repair, where the body requires additional energy to power the cellular processes involved in regenerating damaged tissues and replacing lost proteins.
- The recurrent stress response, which activates various hormonal and metabolic pathways that increase the overall metabolism of the body as it attempts to cope with the injury.
Considering these factors, the correct answer to why hypermetabolism is common with major burns is e. a, b, c.
