The type of shock occurs when the body loses a significant amount of blood

• A. Cardiogenic
• B. Neurogenic
• C. Anaphylactic
• D. Hemorrhagic

Answer: (D)

Shock from losing a lot of blood is hemorrhagic shock, a type of hypovolemic shock caused by a drop in intravascular volume. With less blood in the vessels, preload falls, so the heart can’t maintain adequate stroke volume and cardiac output; the body responds by raising heart rate and constricting vessels to keep pressure up, but continued bleeding leads to inadequate tissue perfusion and eventually organ dysfunction. The other types involve different mechanisms—cardiogenic shock is from the heart's pumping failure, neurogenic from loss of vascular tone due to nerve injury, and anaphylactic from a severe allergic reaction causing widespread vasodilation and fluid leakage. The defining feature here is the actual loss of circulating blood volume.
