Which option is NOT a shock type listed in the material?

• A. Hypovolemic Shock
• B. Cardiogenic Shock
• C. Septic Shock
• D. Immune Shock

Answer: (D)

Shock types are defined by the underlying mechanism causing inadequate tissue perfusion. The standard categories include hypovolemic shock from fluid or blood loss, cardiogenic shock from failing heart pump, and septic shock from infection that triggers systemic inflammation and vasodilation. Immune shock is not a recognized standalone category in most physiology or clinical material; while immune or inflammatory processes can precipitate shock (as in anaphylactic or septic cases), there isn’t a separate category called “immune shock.” Therefore, this option doesn’t fit with the listed shock types. The other three describe true physiologic states with distinct implications for treatment: restore volume and perfusion in hypovolemia, support cardiac output in cardiogenic shock, and treat infection and modulate the inflammatory response in septic shock.
