Strokes

Cerebrovascular accidents, often called strokes, are interruptions to the blood flow in ***** brain. They can be caused by sudden blockage of a blood vessel (ischemic stroke), or rupture of ***** blood ***** (hemorrhagic stroke). 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 ********** possible outcome for a patient who has had a stroke. Two thirds of all ***** occur in people over the age of 65 (5), and it is ***** third most common cause of death in the United States (Dougherty, 1998). ***** are a major cause of disability as well (Byington et. al., 2000).

***** *****s can have sever***** causes. Sometimes an embolism, or blood clot, forms in one part of ***** body and travels to the ***** where it blocks a sm***** ***** vessel. Thrombosis, or artery *****, can also cut ********** blood *****, when a **********ll blood clot f*****ms on ***** arterial plaque. Most thrombotic strokes ***** caused by the combination of blood vessel narrowing and a clot. Hemorrhagic strokes occur when a ***** vessel in the br*****in ruptures. These strokes can vary from very mild to *****. They may be caused ***** high blood pressure, a we*****kness in the ***** vessel, or a combination of both (*****).

The risk fac*****rs f***** stroke can ***** divided into two groups: controllable and uncontrollable. When a person h***** *****al uncontrollable risk factors, it becomes more important for him her to control the ********** that can be.

Uncontrollable ***** factors include

Age: The older the *****, the more likely they may have a stroke.

Gender: ***** men than women ***** strokes

*****: African-Americans and Hispanics have more strokes than Caucasians

Family history

Diabetes

***** of a previous stroke

Controll*****ble risk *****:

***** blood pressure

Heart disease, particularly atrial fibrillation. ***** blood collects in the heart ***** risk of *****ming a blood clot incre*****ses.

***** cholesterol resulting in blood vessel blockage

Sleep apnea, which can cause spikes in ***** *****

*****, which damages blood vessels ***** raises blood pressure

Alcohol abuse

Obesity

***** of a stroke include sudden weakness or feeling of numbness, especially on one side of the body; sudden difficulty speaking or confusion; sudden vision disturbance in one or both eyes: difficulty walk*****g, loss of balance or po***** coordination, or a sudden and severe headache (Barker, 2001). Less commonly, the patient can develop sudden nausea ***** vomiting marked by rapid onset, which may ***** a fever; or ***** brief loss ***** consciousness, which can be as mild as an apparent fainting spell or as severe as convulsion or coma (5)

Emergency room nurses can provide a valuable first line of evaluation by using stroke checklists of symptoms and alerting the triage doctor if symptoms suggest the possibility of a stroke. R*****pid diagnosis allows the medical team the ***** options for treatment whether it is drugs to dissolve the clot or a carotid artery stent (Dougherty, *****) to improve blood
