***** accidents, often called strokes, are interruptions to the blood flow in the brain. They can be caused by sudden blockage of a blood vessel (ischemic stroke), or rupture of a blood vessel (hemorrhagic *****). Strokes are medical emergencies that can cause coma, paralysis, muscle weakness, memory, speech/language or other brain function problems (5). Immediate emergency treatment helps ensure the best possible outcome f***** a patient who has had a stroke. Two thirds of all ***** occur in people over the age of 65 (5), and it is the third most common cause of death in the Un*****ed States (Dougherty, 1998).

Thrombosis, or artery *****, can also cut off blood flow, when a sm*****ll blood clot ***** on the arterial plaque. Most thrombotic strokes ***** caused ***** ***** combination of ***** vessel narrowing and a clot. Hemorrhagic strokes occur when a blood vessel in the br*****in ruptures. These strokes can vary from very mild to major. They may be caused by high blood pressure, a we*****kness in ***** ***** vessel, or a combination of both (5).

***** room nurses c***** provide a valuable first line of evaluation by using stroke checklists of symptoms and alerting the triage doctor if ***** suggest the possibility of a stroke.
