The neurologic functions that are affected by a stroke are
primarily related to
a. the amount of tissue area involved
b. the rapidity of onset of symptoms
c. the brain area perfused by the affected artery
d. the presence or absence of collateral circulation -
Answer-C: The brain area perfused by the affected artery-
clinical manifestation of altered neurologic function differ,
depending primarily on the specific cerebral artery
involved and the area of the brain that is perfused by the
artery. The degree of impairment depends on rapidity of
onset, the size of the lesion, and the presence of collateral
circulation.
A patient is admitted to the hospital with a left hemiplegia.
To determine the size and location and to ascertain

whether a stroke is ischemic or hemorrhagic, the nurse
anticipates that the health care provider will request a
a. CT scan
b. lumbar puncture
c. cerebral arteriogram
d. positron emission tomography (PET) - Answer-A: CT
scan- A CT scan is the most commonly used diagnostic
test to determine the size and location of the lesion and to
differentiate a thrombotic stroke from a hemorrhagic
stroke. Positron emission tomography (PET) will show the
metabolic activity of the brain and provide a depiction of
the extent of tissue damage after a stroke. Lumbar
punctures are not performed routinely because of the
chance of increased intracranial pressure causing
herniation. Cerebral arteriograms are invasive and may
dislodge an embolism or cause further hemorrhage; they
are performed only when no other test can provide the
needed information.
A carotid endarterectomy is being considered as a
treatment for a patient who has had several TIAs. The
nurse explains to the patient that this surgery
,3|Page
a. is used to restore blood to the brain following an
obstruction of a cerebral artery
b. involves intracranial surgery to join a superficial
extracranial artery to an intracranial artery
c. involves removing an atherosclerotic plaque in the
carotid artery to prevent an impending stroke
d. is sued to open a stenosis in a carotid artery with a
balloon and stent to restore cerebral circulation - Answer-
C: Involves removing an atherosclerotic plaque in the
carotid artery to prevent an impending stroke- An
endarterectomy is a removal of an atherosclerotic plaque,
and plaque in the carotid artery may impair circulation
enough to cause a stroke. A carotid endarterectomy is
performed to prevent a cerebrovascular accident (CVA),
as are most other surgical procedures. An extacranial-
intracranial bypass involves cranial surgery to bypass a
sclerotic intacranial artery. Percutaneous transluminal
angioplasty uses a balloon to compress stenotic areas in
the carotid and vertebrobasilar arteries and often includes
inserting a stent to hold the artery open.
In promoting health maintenance for the prevention of
strokes, the nurse understands that the highest risk for the
most common type of stroke is present in
a. African Americans
, 4|Page
b. women who smoke
c.individuals with hypertension and diabetes
d. those who are obese with high dietary fat intake -
Answer-C: Individuals with hypertension and diabetes-
The highest risk factors for thrombotic stroke are
hypertension and diabetes. African Americans have a
higher risk for stroke than do white persons but probably
because they have a greater incidence of hypertension.
Factors such as obesity, diet high in saturated fats and
cholesterol, cigarette smoking, and excessive alcohol use
are also risk factors but carry less risk than hypertension.
A thrombus that develops in a cerebral artery does not
always cause a loss of neurologic function because
a. the body can dissolve the atherosclerotic plaques as
they form
b. some tissues of the brain do not require constant blood
supply to prevent damage
c. circulation through the circle of Willis may provide blood
supply to the affected area of the brain
d. neurologic deficits occur only when major arteries are
occluded by thrombus formation around an atherosclerotic
