Question

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

Answer 1

A carotid endarterectomy is performed on a patient with TIAs to remove atherosclerotic plaques blocking cerebral blood flow and to prevent future strokes.

Step-by-step explanation:

A patient diagnosed with transient ischemic attacks (TIAs), often referred to as mini-strokes, is scheduled for a carotid endarterectomy. The primary purpose of this surgical procedure is to remove atherosclerotic plaques that are blocking the cerebral flow in the carotid arteries.

TIAs occur when there is a temporary disruption in blood flow to parts of the brain, which can lead to a temporary loss of neurological function. A carotid endarterectomy is performed to prevent future TIAs or a full-blown stroke by surgically removing the plaque from the walls of the carotid artery, thereby restoring proper blood flow to the brain.

This treatment is essential for preventing potential strokes, as the blockage, if left untreated, could lead to permanent neurological damage or a more severe cerebrovascular accident (CVA).
