Initiating enteral nutrition timing—what statement best reflects its purpose?

• A. It should be avoided in sepsis
• B. Maintains gut integrity and immune function
• C. It is unnecessary in most ICU patients
• D. It should be started within 24-48 hours if feasible

Answer: (B)

Providing enteral nutrition early focuses on preserving the gut barrier and supporting immune defenses. Feeding through the GI tract nourishes enterocytes, helps maintain the mucosal lining, and sustains gut-associated lymphoid tissue. A healthy gut barrier reduces bacterial translocation and modulates the inflammatory response, which lowers the risk of infections and supports recovery. So, its purpose is best described as maintaining gut integrity and immune function. While starting enteral feeds within 24–48 hours is a common guideline for appropriate patients, saying it should be avoided in sepsis or is unnecessary in most ICU patients does not reflect its primary purpose.
