Which of the following are types of common distributive shock?

Distributive shock is characterized by a failure of the vascular system to maintain adequate perfusion due to widespread vasodilation. The correct answer includes septic shock, neurogenic shock, anaphylactic shock, and psychogenic shock, all of which fall under the category of distributive shock due to their mechanisms that lead to a relative hypovolemia caused by changes in vascular tone.

Septic shock occurs as a result of systemic infection and the accompanying inflammatory response that causes severe vasodilation and increased permeability of blood vessels. Neurogenic shock is typically caused by a spinal cord injury leading to a loss of sympathetic tone, resulting in vasodilation. Anaphylactic shock, which is a severe allergic reaction, leads to vasodilation and increased capillary permeability due to the release of histamines and other mediators. Psychogenic shock stems from a sudden emotional stress that can lead to transient vasomotor collapse, though less common, it is associated with distributive shock characteristics.

Other options provided contain types of shock that are not classified as distributive. For example, cardiogenic shock is primarily due to the heart's inability to pump effectively, while hypovolemic shock is caused by a significant loss of blood volume. Hence, the key characteristics
