Answer to Question 1

ANS: B
This procedure is performed to bypass stenotic or occlusive vascular disease and provides additional blood to the cerebral circulation.

Answer to Question 2

ANS: B
Air embolism can occur if the patient is sitting upright during a procedure. The brain is higher than the heart in this position. Venous pressure is lower than atmospheric pressure and can allow for entry of air into the heart via an open venous channel.
