Which artery is most commonly Left middle cerebral artery
involved in a large-vessel ischemic
stroke affecting Broca's area? Explanation:
Broca's area is located in the dominant frontal
lobe, typically supplied by the superior division
of the left middle cerebral artery.
A patient with a suspected Lumbar puncture
subarachnoid hemorrhage has a
negative CT scan. What is the next Explanation:
recommended diagnostic step? If CT is negative but suspicion for SAH remains
high, lumbar puncture is recommended to assess
for xanthochromia and RBCs.
Which clinical finding is most Locked-in syndrome
characteristic of a basilar artery
occlusion? Explanation:
Basilar artery occlusion can cause pontine
infarction leading to quadriplegia with preserved
consciousness—locked-in syndrome.
,Which medication is first-line for Nicardipine
blood pressure control in acute Explanation:
intracerebral hemorrhage? Nicardipine is commonly used because it is easily
titrated and avoids increasing intracranial
pressure.
Which stroke syndrome is most Lacunar stroke
associated with pure motor Explanation:
hemiparesis? Pure motor hemiparesis is a classic presentation
of a lacunar infarct affecting the internal capsule.
What is the primary purpose of To maintain cerebral perfusion pressure
permissive hypertension in acute Explanation:
ischemic stroke? Higher blood pressure helps maintain perfusion
to the ischemic penumbra before reperfusion
therapy.
Which diagnostic test is most Diffusion-weighted MRI
sensitive for early detection of Explanation:
ischemic stroke? Diffusion-weighted MRI detects ischemic
changes within minutes, making it the most
sensitive early test.
A patient with atrial fibrillation Cardioembolism
presents with sudden-onset aphasia Explanation:
and right-sided weakness. What is Atrial fibrillation increases the risk of emboli
the most likely stroke mechanism? forming in the atria, leading to cardioembolic
stroke.
Which electrolyte imbalance Hyponatremia
increases the risk of seizures after Explanation:
stroke? Hyponatremia can cause cerebral edema and
increase neuronal excitability, raising seizure risk.
, Which condition is most associated Subarachnoid hemorrhage
with a 'thunderclap' headache? Explanation:
A thunderclap headache is classic for
subarachnoid hemorrhage due to sudden
increased intracranial pressure.
Which cranial nerve deficit is most Ipsilateral CN III palsy
associated with an uncal Explanation:
herniation? Uncal herniation compresses CN III, causing
ipsilateral fixed and dilated pupil.
Which finding suggests increased Cushing's triad
intracranial pressure? Explanation:
Cushing's triad—hypertension, bradycardia, and
irregular respirations—is a classic sign of
increased ICP.
Which stroke type is most Embolic stroke
associated with atrial fibrillation? Explanation:
Atrial fibrillation predisposes to emboli forming in
the atria, leading to embolic strokes.
Which medication is used to Prothrombin complex concentrate
reverse warfarin in acute Explanation:
intracranial hemorrhage? PCC rapidly reverses warfarin's effects and is
preferred over FFP due to faster action.
Which symptom is most associated Ataxia
with cerebellar stroke? Explanation:
Cerebellar strokes commonly cause ataxia due to
impaired coordination.
