When circulatory shock occurs, there is massive vasodilation causing pooling of the blood in the periphery of the body
An ICU nurse caring for a patient in circulatory shock should know that the pooling of blood in the periphery leads to what pathophysiological effect?
A) Increased stroke volume
B) Increased cardiac output
C) Decreased heart rate
D) Decreased venous return
Ans: D
Feedback:
Pooling of blood in the periphery results in decreased venous return. Decreased venous return results in decreased stroke volume and decreased cardiac output. Decreased cardiac output, in turn, causes decreased blood pressure and, ultimately, decreased tissue perfusion. Heart rate increases in an attempt to meet the demands of the body.
