Question

Septic shock usually results from?

1) Release of endotoxin upon lysis of cells
2) Infection with the malaria parasite
3) Failure to be vaccinated
4) Inhalation of endospores
5) Overreaction of the immune system

Answer 1

Septic shock usually results from the release of endotoxin upon lysis of cells. The immune system's response to gram-negative bacterial infections can lead to a severe drop in blood pressure, organ failure, and death. It is not caused by an overreaction of the immune system.

Step-by-step explanation:

Septic shock usually results from the release of endotoxin upon lysis of cells. When gram-negative bacterial infections reach the bloodstream, large quantities of LPS (endotoxin) can be released, causing a severe and overwhelming immune and inflammatory response. This response leads to a drop in blood pressure, intravascular blood clotting, organ failure, and ultimately death. It is important to note that septic shock is not caused by an overreaction of the immune system, but rather a dysregulation of the immune response to the infection.
