According to the SIRS continuum, what is the correct progression?

• A. Inflammatory response -> Sepsis -> Septic shock -> MODS
• B. Inflammatory response -> MODS -> Sepsis -> Septic shock
• C. Sepsis -> Inflammatory response -> Septic shock -> MODS
• D. Inflammatory response -> Sepsis -> Septic shock -> MODS

Answer: (D)

The key idea is the sequential escalation of the body’s response to a severe insult. It starts with the inflammatory response that kicks in to fight the trigger. When that trigger is an infection, the systemic inflammatory response becomes sepsis. If sepsis progresses with ongoing circulatory collapse and poor perfusion despite fluids, it advances to septic shock. If the process continues and worsens, multiple organ systems begin to fail, resulting in MODS. So the correct progression is inflammatory response → sepsis → septic shock → MODS. This order reflects how the body's response escalates from initial inflammation to systemic infection, then to dangerous circulatory failure, and finally to widespread organ dysfunction. The other sequences would misplace the onset of organ dysfunction or reverse the natural development from inflammation to systemic infection and failure.
