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

ischemic stroke

Rationale: Ischemic strokes account for 80% of all strokes. An ischemic stroke occurs when a blood vessel becomes blocked, usually by a blood clot. This causes a portion of the brain to become deprived of oxygen and to stop functioning properly. Rapid diagnosis and treatment of acute ischemic strokes is essential when caring for a patient, as this will reduce death and disability from stroke. The goal for optimum recovery is to begin treatment within 3 hours of the onset of stroke symptoms.


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: Transient Ischemic Attacks (TIAs) are often called mini-strokes. The symptoms are the same as for a major stroke, but they disappear in a short period of time without any residual deficits. In a TIA, the blood clot that is blocking the flow of blood in the brain breaks up on its own and the symptoms disappear. TIA's generally don't cause severe brain damage, but they are a warning sign of a future stroke and should be taken seriously. The prevalence of transient ischemic attacks increases with age, and up to 40 percent of all people who suffer a TIA will go on to experience a stroke.


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:

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

stroke

Rationale:

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

coumadin

Rationale:

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

head CT

Rationale:

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

intercranial hemorrhage

Rationale:

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

AVM

Rationale:

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

TPA

Rationale:
