NR325 Exam 2 – Questions With Fully Explained
Solutions
Ischemic strokes Correct Answer - thrombotic and embolic
Thrombotic stroke Correct Answer - occurs from injury to a
blood vessel wall and formation of a blood clot
-results from narrowing of blood vessel
-most common cause of strokes (60%)
-often associated with HTN/DM
-often proceeded by TIA
Embolic stroke Correct Answer - occurs when an embolus
lodges in and occludes a cerebral artery
-results in infarction and edema of area supplied by involved vessel
-2nd most common cause of strokes
-warning signs less common
-patient usually conscious
-reccurence is common
Hemorrhagic stroke Correct Answer - results from bleeding
into the brain caused by vessel rupture
-sudden onset
-progresses over minutes-hours
-typically occurs during activity
BEFAST Correct Answer - Balance, eyes, face, arms, speech,
time
When a possible stroke patient comes in... Correct Answer - 1)
call stroke team
2)test sugars
3)assesment
, 4)CT scan to determine type of stroke
TIA Correct Answer - a transient episode of neurologic
dysfunction caused by focal brain, spinal cord, or retinal ischemia
but without acute infarction of brain
-S/S lasts <1 hr
-no way to predict outcome
-history of TIA increases stroke risk
