What are examples of distributive shock?

1. Neurogenic, septic, traumatic

2. Neurogenic, obstructive, septic

3. Cardiogenic, anaphylactic, hypovolemic

4. Neurogenic, anaphylactic, septic

The correct answer is: Neurogenic, anaphylactic, septic

Distributive shock is characterized by a problem with the distribution of blood flow rather than an issue with the pump (the heart) itself. This type of shock can be fundamental in recognizing various medical emergencies where blood vessels dilate excessively, leading to a decrease in systemic vascular resistance and, consequently, inadequate perfusion of tissues. Neurogenic shock occurs when there is a loss of sympathetic tone resulting in vasodilation, which is often seen in spinal cord injuries. Anaphylactic shock is a severe allergic reaction that causes widespread vasodilation and increased vascular permeability. Septic shock is due to systemic infection that leads to an overwhelming immune response, triggering vasodilation and increased capillary leakage. This combination clearly reflects conditions that lead to impaired tissue perfusion due to disrupted blood flow, which is the hallmark of distributive shock. Other options contain combinations of shock types that either misclassify those that are not part of distributive shock, such as cardiogenic shock, which is related to heart function, or obstructive shock, which involves physical obstruction of blood flow. Therefore, the chosen answer accurately represents examples of distributive shock.
