A stroke that occurs when a blood vessel that carries oxygen to the brain bursts and spills blood into the brain is a:

hemorrhagic stroke

Rationale: A hemorrhagic stroke occurs when a blood vessel that carries oxygen to the brain burst and spills blood into the brain. When this happens, a portion of the brain becomes deprived of oxygen and will stop functioning. Hemorrhagic stroke accounts for about 20% of strokes. The most common signs of a hemorrhagic stroke are severe headache, change in level of consciousness, vomiting, and deficits on one side of the body. Treating a hemorrhagic stroke focuses on controlling the bleeding, and controlling the increased amount of pressure in the cranium. The treatment will focus on the cause of the bleeding and the severity of the patient's symptoms.


A patient that presents with symptoms of a stroke should have a stat:

head CT

Rationale: A non-contrast head CT scan should be performed immediately, as soon as the patient presents to the hospital for stroke symptoms. A CT can detect damage to the brain tissue, and if there is any presence of bleeding in the brain. An MRI may be ordered on stable patients that have complex stroke symptoms, but a CT should be performed on patients that present with acute symptoms. A CT scan is faster than an MRI, and can determine if a stroke is due to bleeding or clotting.


A congenital abnormality that is a common cause of hemorrhagic stroke in young people is:

AVM

Rationale:

A medication that makes a patient at a higher risk of developing a hemorrhagic stroke is:

coumadin

Rationale:

A type of hemorrhagic stroke in which the patient has bleeding directly into the brain matter is:

intercranial hemorrhage

Rationale:

A stroke that occurs because a blood vessel becomes blocked is an:

ischemic stroke

Rationale:

An acute neurological deficit caused by a vascular disorder that injures the brain tissue is:

stroke

Rationale:

When caring for a patient that presents with symptoms of a stroke, after stabilizing an airway and circulation, the next important step is to obtain information regarding:

onset of symptoms

Rationale:

A treatment for ischemic stroke that helps restore blood flow to the brain by dissolving a clot is:

TPA

Rationale:

A patient that presents with stroke-like symptoms, but then the symptoms disappear after a short period of time, may have had a (an):

transient ischemic attack (TIA)

Rationale:
