A patient with carotid atherosclerosis asks the nurse to describe a carotid
endarterectomy. Which response by the nurse is accurate?
a. "The obstructing plaque is surgically removed from inside an artery
in the neck."
b. "The diseased portion of the artery in the brain is replaced with a
synthetic graft."
c. "A wire is threaded through an artery in the leg to the clots in the
carotid artery, and the clots are removed."
d. "A catheter with a deflated balloon is positioned at the narrow area,
and the balloon is inflated to flatten the plaque." - ✔✔✔✔✔✔-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.
A patient admitted with possible stroke has been aphasic for 3 hours,
and his current blood pressure (BP) is 174/34 mm Hg. Which order by
the health care provider should the nurse question?
a. Keep head of bed elevated at least 30 degrees.
b. Infuse normal saline intravenously at 75 mL/hr.
c. Start a labetalol drip to keep BP less than 140/30 mm Hg.
d. Administer tissue plasminogen activator (tPA) intravenously per
protocol. - ✔✔✔✔✔✔-ANS: C
Because elevated BP may be a protective response to maintain cerebral
perfusion, antihypertensive therapy is recommended only if mean arterial
pressure (MAP) is greater than130 mm Hg or systolic pressure is greater

, than 220 mm Hg. Fluid intake should be 1500 to 2000 mL/day to maintain
cerebral blood flow. The head of the bed should be elevated to at least 30
degrees unless the patient has symptoms of poor tissue perfusion. tPA
may be administered if the patient meets the other criteria for tPA use.
A patient arrives in the emergency department with hemiparesis and
dysarthria that started 2 hours previously, and health records show a
history of several transient ischemic attacks (TIAs). The nurse
anticipates preparing the patient for
a.surgical endarterectomy.
b.transluminal angioplasty.
c. intravenous heparin drip administration.
d.tissue plasminogen activator (tPA) infusion. - ✔✔✔✔✔✔-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.
