A Temporary Loss of Consciousness Due to a Decrease in Blood

Question

A temporary loss of consciousness due to a decrease in blood flow to the brain is termed
A) stroke.
B) coronary ischemia.
C) cerebral hypoxia.
D) fainting.
E) cerebral hypotension.

Accepted Answer

Fainting, also known as syncope, is a temporary loss of consciousness due to a decrease in blood flow to the brain. This can be caused by a variety of factors, such as standing up too quickly, dehydration, or emotional stress. It is not typically a serious condition, although recurrent episodes should be evaluated by a medical professional.

The other choices are not accurate descriptions of fainting. A stroke involves a disruption of blood flow to the brain that can result in permanent damage. Coronary ischemia refers to decreased blood flow to the heart, and cerebral hypoxia/hypotension both involve inadequate oxygen supply to the brain. These conditions can also result in loss of consciousness, but they are not the same as fainting.
