Which type of shock is septic shock considered to be?

• A. Cardiogenic shock
• B. Distributive shock
• C. Obstructive shock
• D. Hypovolemic shock

Answer: (B)

Distributive shock is defined by widespread vasodilation and misdistribution of blood flow, so the organs may not receive enough perfusion even when the heart is pumping adequately. Septic shock fits here because infection triggers an inflammatory cascade that relaxes blood vessels and increases capillary permeability. The result is a drop in systemic vascular resistance and a circulating volume that’s effectively too low for the vasculature’s capacity, leading to poor tissue perfusion. This contrasts with cardiogenic shock, which comes from the heart’s inability to pump effectively; obstructive shock, from a blockage that impedes blood flow; and hypovolemic shock, from a true loss of blood or fluids.
