What is the best method of decreasing mortality and morbidity of stokes
Prevention!,!

3min
- 5min for cellular death
_______ major cause of ischemic stroke
Atherosclerosis
What effects blood flow to the brain?
Cardiac out put
CO2
Intracranial pressures
What comorbidity is the most common cause of a stroke?
A fib
- due to blood pooling in the atrium making it easier for a blood clot to for,
What are the 3 types of strokes

What is the single most important tool to diagnose a stroke

Arm weakness
Speech difficulty
What does “door to drug time” refer to
How long does it take a person who is a possible stroke get from ambulance to the ct

It is a single dose
Less room for an error to occur half life of 20 min
TNK
Helps to dissolve blood clots
- disadvantage = needs to be given w/in 4.5 hours of onset of symptoms
Collaboration care for strokes helps to prevent further brain damage and reduce disability
True or false
True
Nursings main goal for stroke patient is to
Maintain a stable or improve loc in patient
