Answer to Question 1

ANS: A
In a carotid endarterectomy, the carotid artery is incised and the plaque is removed. The response beginning, The diseased portion of the artery in the brain is replaced describes an arterial graft procedure. The answer beginning, A catheter with a deflated balloon is positioned at the narrow area describes an angioplasty. The final response beginning, A wire is threaded through the artery describes the mechanical embolus removal in cerebral ischemia (MERCI) procedure.

Answer to Question 2

ANS: D
The patient's history and clinical manifestations suggest an acute ischemic stroke and a patient who is seen within 4.5 hours of stroke onset is likely to receive tPA (after screening with a CT scan). Heparin administration in the emergency phase is not indicated. Emergent carotid transluminal angioplasty or endarterectomy is not indicated for the patient who is having an acute ischemic stroke.
