Stroke Flashcards
brief period of localized cerebral ischemia
less than 24hrs
warning signal of an ischemic thrombotic stoke
transient ischemic attack (TIA)
blockage or stenosis of a cerebral artery
ischemic stroke
occlusion on artery wall
occur while people are resting or sleeping
decreased BP leads to less pressure to push blood thru
begins with TIA, worsens over 1-2days
thrombotic stroke
occurs when a clot is free floating
occurs when pt is awake and active
sudden onset with immediate deficits
embolic stroke
sudden bleeding into brain
occurs with sustained increase is BP
impairs absorption and circulation of cerebrospinal fluid
hemorrhagic stroke
normal physiologic response to an embolic clot
increased systemic BP
1 prevention for CVA
antihypertensives
followed by smoking cessation (lifestyle/diet)
can understand but can only respond in short pharases
:broken speech
broca’s aphasia
cannot understand spoken or written words
fluent speech but inappropriate content
wernicke’s aphasia
cardiovascular health indicator
how prone they are to plaque formation
Micro Albumin
prevention pharmacologics
antiplatelets
:plavix, aspirin
used to treat pts with TIAs or had a previous stroke
antiplatelets
aspirin, plavix
ordered to treat an ischemic stroke
heparin, coumadin, lovenox
never administered to a client with a hemorrhagic stroke
antioags
used to treat thrombotic stroke
fibrinolytics
fibrinolytics “window of opportunity”
given w/in 3hrs of onset of manifestations after confirming on CT of an ischemic stroke
contraindicated in hemorrhagic stroke
antiplatelets
dysphagia more common with…
left hemisphere CVA
symptoms with left hemisphere CVA
langauge talking/ understanding reading/ writing memory depression math comprehension slow cautious behavior
right hemisphere CVA s/s
perceptual skills understanding what we see, hear, touch judging size, speed, distance neglect syndrome poor impulse control short attention span
ACT FAST
F: facial symmetry
A: arms drift
S: speech
T: time is brain tissue
