What vascular anatomy in the brain provides collateral blood flow between the Adrea and
posterior circulation of the brain, protecting against ischemia in the event of vessel disease or
damage?
Circle of Willis
internal carotid arteries
anterior cerebral artery
anterior communicating artery - ANS ✔✔Circle of Willis
Your 75 year old male patient has sudden onset of aphasia facial drooping to the left side severe
left arm and leg impairment and a conjugate gaze to the right.
They started about one hour ago and the patient was last seen normal about two hours ago
what would be your diagnosis and transport decision?
- Large vessel occlusion (LVO) cerebral vascular accident (CVA) and transport to a
comprehensive stroke center
- the patient is post active from previous seizure. Transport to your nearest ED for stabilization.
- Left-sided cerebral vascular accident (CVA) and transport to primary stroke center for
evaluation possible TPA administration.
- Transient ischemic attack (TIA) and transport would be up to the family or patient if he's able
to answer questions. - ANS ✔✔Large vessel occlusion (LVO) cerebral vascular accident (CVA)

, This patient would have a rescore of at least seven from the information above and would likely
be suffering from a large special occlusion. This makes the transport to a comprehensive stroke
center extremely critical so that the patient can have access to interventional radiology and
mechanical thrombectomy. This patient is most likely suffering from a large LVOCVA. The TPA
may be helpful, it may be unsuccessful in breaking up a larger clot. It may also cost smaller clots
to break off the larger clot and caused further inclusions downstream. Current guidelines

A person impacts a wall head first and then the head recoils back. This is an example of which of
the following types of gravitational traumatic brain injuries?
Newton force injury
Rotational force injury
Transitional force injury
Transitional injury - ANS ✔✔Transitional injury
This lobe of the brain controls behavior and emotional control, and is likely what has been
damaged during a traumatic brain injury of the patient's personality changes? - ANS ✔✔Frontal
Lobe
With decerebrate posturing in a patient with a head injury, you might find which of the
following on assessment?
central neurogenic hyperventilation
withdraw from Pain
GCS of 15
