Question

: Prolonged thoracic aortic cross-clamp time is most likely to result in a loss of:

a) Pulmonary compliance
b) Renal blood flow
c) Coronary perfusion
d) Cerebral perfusion

Answer 1

Prolonged thoracic aortic cross-clamp time can result in a loss of cerebral perfusion.

Step-by-step explanation:

Prolonged thoracic aortic cross-clamp time is most likely to result in a loss of:

The correct answer is d) Cerebral perfusion.

When the thoracic aorta is cross-clamped for a prolonged period, blood flow to the brain is compromised, leading to a decrease in cerebral perfusion. This can result in neurological deficits and potentially permanent brain damage.
