When a person is in shock, impairment in cellular metabolism is caused by:
A) release of toxic substances.
B) free radical formation.
C) inadequate tissue perfusion.
D) lack of nervous or endocrine stimulation.

Question

Quizplus · Accepted Answer

Shock leads to inadequate tissue perfusion, which means that cells are not receiving enough oxygen and nutrients required for cellular metabolism. This impairs cellular metabolism and can lead to cell death. Release of toxic substances or free radical formation can contribute to cellular damage, but they are not the primary cause of impairment in cellular metabolism in shock. Lack of nervous or endocrine stimulation can also contribute to shock, but it is not the cause of impairment in cellular metabolism.
