A patient presents with a left D.
hemispheric hemorrhagic stroke. Rationale: Uncal herniation occurs due to
He a shift
develops a shift and an uncal caused by unilateral mass effect. As the
herniation. Which of the following left
would be a clinical sign of the hemisphere shifts towards the right, it can
herniation? herniate
a. a constricted contralateral pupil under the falx cerebri. Cranial nerve III
b. a constricted ipsilateral pupil (oculomotor) becomes stretched on the
c. a dilated contralateral pupil affective
d. a dilated ipsilateral pupil side, resulting in a dilation and loss of
pupillary
reaction of the ipsilateral pupil. Cranial
nerves
(except for CN IV) remain on the same
side and
do not cross, resulting in ipsilateral
symptoms.
,Which of the following types of B
stroke is most likely to develop Rationale: A subarachnoid hemorrhage
hydrocephalus? causes
a. a lacunar stroke blood to be introduced with cerebral spinal
b. a subarachnoid hemorrhage fluid
c. a cardioembolic stroke (CSF). The absorption of CSF occurs
d. a thrombotic stroke through the
arachnoid villi into the venous sinuses.
Blood,
being thicker than CSF, will obstruct the
arachnoid
villi and cause an increase in circulating
CSF (lack
of absorption). This frequently produces
communicating hydrocephalus.
Which of the following would be B.
used to describe the appearance Rationale: Rust-colored CSF, when
of obtained by
a sample of cerebral spinal fluid lumbar tap or from a ventriculostomy,
(CSF) if xanthochromes were indicates
present, indicating an older bleed? the presence of xanthochromes and
a. bloody means the
b. rust-colored patient has experienced a subarachnoid
c. cloudy hemorrhage in the recent past. It is a sign
d. Thick and pustular of old
blood in the CSF.
,A patient following a coronary A
artery bypass grafting (CABG) Rationale: A watershed stroke occurs with
procedure is slow to awaken. A CT ischemia between two large vascular
scan isobtained and an ischemic territories
stroke is found between the such as the
anterior anterior and middle cerebral arteries. It is
cerebral artery (ACA) and frequently a result of hypoperfused states
middlecerebral artery (MCA) such as
territories. What type of stroke has those during
this patient experienced? cardiopulmonary bypass. Moyamoya
a. a watershed stroke vessels
b. a Moyamoya stroke develop during progressive narrowing of
c. a lacunar stroke the
d. a cardioembolic stroke carotid artery
and usually result in hemorrhagic stroke.
Lacunar
strokes are a result of chronic
hypertension, and
cardioembolic stroke is associated with
atrial
fibrillation.
A patient presenting with left lower A
extremity weakness upper Rationale: The anterior cerebral artery
extremity supplies
weakness and urinary blood to the medial portion of the frontal
incontinence lobe. A
most likely involves which vascular portion of the motor strip controls the lower
territory? extremities while the middle cerebral artery
a. the anterior cerebral artery supplies blood to the portion that controls
b. the middle cerebral artery the
c. the posterior cerebral artery upper extremities and face. The posterior
d. the basilar artery cerebral
artery supplies blood to the occipital lobe
and
basilar artery to the brain stem.
, Locked-in syndrome would involve D
which of the following cerebral Rationale: Occlusion or rupture of the
arteries? basilar
a. the anterior communicating artery can result in a paralysis called
artery locked-in
b. the carotid artery syndrome.It affects the PONS. This is a
c. the vertebral artery loss of
d. the basilar artery motor control, but the patient maintains
awareness. Carotid artery provides blood
to the
anterior circulation of the Circle of Willis.
The
vertebral artery supplies blood to the
basilar
artery. The anterior communicating artery
connects the two anterior cerebral arteries.
Where in the brain are the dural B
venous sinuses located? Rationale: The subdural space is located
a. the epidural space between
b. the subdural space the endosteal layer and the meningeal
c. the subarachnoid space layer of
d. the subpial space the dura mater. The venous sinuses are
located in
the subdural space. The CSF circulates in
the
subarachnoid space, and the epidural is a
potential space with arterial supply. There
is not a
subpial space.
