Which of the following is not listed as a type of shock?

• A. Cardiogenic
• B. Neurogenic (Vasogenic)
• C. Hypovolemic
• D. Septic

Answer: (D)

The main idea is that this list presents three primary forms of shock: cardiogenic, hypovolemic, and neurogenic (vasogenic). Each of these has a distinct mechanism for causing reduced tissue perfusion—cardiogenic from the heart’s inability to pump effectively, hypovolemic from loss of intravascular volume, and neurogenic from loss of autonomic vascular tone leading to widespread vasodilation.

Septic shock is a real and important condition, caused by infection that triggers severe vasodilation and capillary leakage. However, in this particular question’s scope, septic shock isn’t included as one of the listed primary shock types, so it’s the option that isn’t listed. The other three fit the stated categories: they represent the classic mechanisms you’re expected to recognize in this context.
