The risk of hypovolemic shock is high with acute mesenteric arterial insufficiency because:
A) the resulting liver failure causes a deficit of plasma proteins and a loss of oncotic pressure.
B) ischemia alters mucosal membrane permeability and fluid is shifted to the bowel wall and peritoneum.
C) massive bleeding occurs in the gastrointestinal tract.
D) overstimulation of the parasympathetic nervous system results in ischemic injury to the intestinal wall.

Question

Quizplus · Accepted Answer

Acute mesenteric arterial insufficiency causes ischemia, which alters mucosal membrane permeability and results in fluid shifting to the bowel wall and peritoneum, leading to hypovolemia and potential hypovolemic shock. The other options (A, C, and D) do not accurately describe the mechanism behind the risk of hypovolemic shock in this condition.
