Which classification of shock is characterized by systemic infection leading to vasodilation?

Cardiogenic shock
Septic shock
Anaphylactic shock
Neurogenic shock

The correct answer is: Septic shock

Septic shock is specifically associated with a systemic infection causing an overwhelming immune response that leads to widespread vasodilation. In this condition, pathogens or their toxins enter the bloodstream, triggering inflammation and the release of various mediators that result in the widening of blood vessels. This vasodilation decreases systemic vascular resistance, which can lead to a drop in blood pressure and inadequate perfusion of vital organs. This response is a critical aspect of the body's attempt to manage the infection but ultimately results in the clinical state of shock. Recognizing septic shock is essential for prompt treatment, which often includes aggressive fluid resuscitation and antibiotics to address the underlying infection. Other types of shock, like cardiogenic, anaphylactic, and neurogenic shock, have distinctive causes and mechanisms that do not primarily involve systemic infection leading to vasodilation.
