A patient diagnosed with transient ischemic attacks (TIAs) is scheduled for a carotid endarterectomy. The nurse explains that this procedure will be done for what purpose?
A) To decrease cerebral edema
B) To prevent seizure activity that is common following a TIA
C) To remove atherosclerotic plaques blocking cerebral flow
D) To determine the cause of the TIA
Ans: C
Feedback:
The main surgical procedure for select patients with TIAs is carotid endarterectomy, the removal of an atherosclerotic plaque or thrombus from the carotid artery to prevent stroke in
patients with occlusive disease of the extracranial arteries. An endarterectomy does not decrease cerebral edema, prevent seizure activity, or determine the cause of a TIA.
