Sepsis is defined as:

• A. The body's extreme response to an infection
• B. A mild allergic reaction
• C. A chronic fatigue syndrome
• D. A harmless condition

Answer: (A)

Sepsis is the body's extreme, dysregulated response to an infection that can cause widespread tissue damage and organ dysfunction. The defining idea is that the immune system’s reaction to an infection becomes so amplified and uncontrolled that it harms the body's own tissues, not just the invading organisms. This is why the statement describing sepsis as the body's extreme response to an infection is the best fit. It’s not simply a mild allergic reaction, not chronic fatigue syndrome, and not a harmless condition. Recognizing this dangerous systemic response is important because it requires urgent treatment to prevent progression to organ failure or septic shock.
