What's the first major arterial branch of the aorta is the? - Correct answer-Innominate
artery or brachiocephalic artery
The vertebral artery usually
... [Show More] arises from the: - Correct answer-Subclavian Artery
The incidence of new strokes per year is: - Correct answer-from 500,000 to 700,000
The abbreviation TIA stands for: - Correct answer-Transient Ischemic Attack
A TIA of the right anterior hemisphere of the brain will likely affect: - Correct answer-The
left side of the body - affects the side of the body opposite that of the ischemic
hemisphere
Amaurosis Fugax related to an internal carotid lesion will cause: - Correct answerTemporary blindness or shadowing of the ipsilateral eye. affects same side since
thromboembolic activity from ulcerated ipsilateral carotid atheroma is suspected
A transient ischemic attack: - Correct answer-Resolves within 24 hours. TIA often last
just a few minutes
Simultaneous bilateral ocular symptoms in the patient with suspected cerebrovascular
disease generally originate form: - Correct answer-The vertebrobasilar arteries . usually
originate in the posterior circulation , as the visual cortex is in the occipital lobe. The
specific binocular symptom of homonymous hemianopia results from obstruction of a
middle cerebral artery branch, not the vertebrobasilar system
What are symptoms when vertebrobasilar circulation is effected? - Correct answerVertigo, dizziness, ataxia, or other bilateral or global symptoms .
What are symptoms when anterior circulation is effected? - Correct answer-Facial
Asymmetry, unilateral
What accurately defines RIND also called stroke with recovery? - Correct answer-A
neurologic ischemic deficit that resolves completely after 24 hours. Describes an
intracranial ischemic event that does not resolve within 24 hours but thereafter
completely resolves.
A 56- year old patient reports loss of vision in her left eye two days ago, with total
resolution in 10 minutes. Yesterday morning she developed weakness and numbness in
her right hand and was unable to hold her coffee cup. This afternoon her hand strength
is about 90% normal, with normal sensation. Clinically she has: - Correct answer-Stroke
because it has persisted longer than 24 hours and has not resolved completely
The infraorbital artery is a terminal branch of the: - Correct answer-Maxillary Artery . It
creates one of the potential anastomoses with orbital branches that can provide
collateral pathways in the even of carotid obstruction
Amaurosis Fugax can be interpreted as a: - Correct answer-Transient Ischemic Attack
of the eye.
Dysphagia is : - Correct answer-Difficulty swallowing. Symptom associated with
vertebrobasilar insufficiency.
A binocular disturbance that disrupts vision in half the visual field of both eyes is called:
- Correct answer-Homonymous Hemianopia
Paresthesia refers to: - Correct answer-tingling sensation
A patient describes a 30-minute episode of garbled speech. This is called: - Correct
answer-Dysphasia . Aphasia is widely used as well but technically this is incorrect, since
it means "absence of speech."
A right-handed patient experiences a 30-minute episode of dysphasia. Which area of
circulation is suspect? - Correct answer-Left hemisphere . The speech area of the
cortex is in the temporal lobe of the dominant hemisphere [Show Less]
