The nurse recognizes that a patient with sepsis is at risk to develop hypotension. Which pathophysiological process is responsible for this symptom?
Vasodilation and fluid shift out of the vascular space
Platelet aggregation and thrombus formation
Decreased blood glucose and oliguria
Hypoxemia and anaerobic metabolism
The Correct Answer is A
Choice A reason: In sepsis, inflammatory mediators cause vasodilation and increased capillary permeability, leading to fluid leaking out of the vascular space, resulting in hypotension.
Choice B reason: Platelet aggregation and thrombus formation can occur in sepsis but are more related to disseminated intravascular coagulation (DIC) rather than directly causing hypotension.
Choice C reason: Decreased blood glucose and oliguria can be consequences of sepsis but are not the primary pathophysiological processes responsible for hypotension.
Choice D reason: Hypoxemia and anaerobic metabolism may result from the effects of sepsis on the body, including hypotension, but they are not the direct cause of hypotension.
