what vessel usually breaks going to the brain that causes a stroke?
|
carotid artery
|
|
the main thing that causes a stroke is ...
|
HTN
hypertension |
|
what is a vasospasm?
|
cerebral artery shuts off for a sec. and the opens up causing a TIA ( a mini stroke )
|
|
CVA is called ...
|
Cerebro vascular Disease
|
|
Again, things that cause CVA are
arteriosclerosis (plack buildup) hypertensive changes Vasospasm (on/off thing in brain Inflammatin (swelling/coagulation in arteries in the brain Embolism. what is an Embolism? |
blood, air, or fat plack travels to lungs, heart, or brain. A fat emboli can even get to the kidneys, heck anywhere in body
|
|
it takes about 4 minutes for a blood shut off to do irrepruble damage, like to the brain. So, a stroke will always result in ...
|
permanent disability
and permenant brain damage ***************************** 3rd largest cause of death in US |
|
TIA means transient Eschemic Attack
what is this? |
TIA used to be called a mini stroke...*****************
DEF: TIA=a stroke that resolves itself in 24 hours. ******************************** can be a warning sign of an impending stroke. So TIA says "something has happened! Something happened, from lipids, a spasm, a tiny clot went thru, (a clotting problem, or a tiny embolism) or maybe a cardiovascular problem. Trauma to a long bone, or marrow or fat from that got loose. A warning sign bigger thing is going on. |
|
ataxia means
|
ability to move muscles
so muscle movement |
|
what does paresthsias mean
|
not normal feelings like tinglings bugs crawling on you
|
|
TIAs *************************
what ae need to know is that they are RAPID ONSET sO... A PT SAID "i PASSED OUT, DOWN AND THEN FELT TINGLES ON MY LEFT SIDE AND MY SPEECH WAS SLURRED BUT THAT ALL WENT AWAY YESTERDAY. WHAT WOULD THE DOCTOR ORDER? |
A CT CAT SCAN
AN MRI IT CAN LOOK AT THE BRAIN AND CARATOIDS. MAYBE ORDER A CARTIAC WORKUP |
|
SO WE ARE DOING A HISTORY OF THIS PT, WHAT DO WE LOOK FOR?
|
Hx OF SMOKING
ALCOHOL COCAINE (IN THE YOUNG& TIAs) SAY WHAT WERE YOU DOING WHEN THIS HAPPENED. HOW LONG DID IT LAST? YOU SAID YOU WERE NUMB ON THE LEFT SIDE? DIFFICULTLY WALKING? SO ONSET DURATION INTENSITY OF THIS EVENT FIRST TIME THIS HAS HAPPENED TO YOU? |
|
SO THE PT COMES INTO THE ER AND TELLS ALL THIS STUFF. THE MD ORDERS A MRI, CT SCAN, LOOKING THE HEART FOR THINGS LIKE AF OR ATRIAL FIBLUATION WHY? THE HEART?
|
THE VALVES B/C LOOKING FOR ATRIAL FIBULATION B/C VALVE Dx CAN CAUSE CLOTS SO THEY WILL DO DOING CARDIO WORKUPS AND PUT THEM ON
HEPARIN IMMEDIATELY B/C THEY DON'T WANT THE BLOOD TO CLOT WHEN SENT HOME MIGHT GIVE THEY PUT THEM ON PLAVIX,ASPIRIN, TO KEEP CLOTS FROM FORMING |
|
WHAT WOULD A NURSE ASK SOMEONE WHO JUST HAD A TIA AND IS GOING HOME?
|
DO YOU LIVE ALONE?
DO YOU HAVE STAIRS?COULD BE GOOD DO YOU HAVE A PHONE? ARE YOU RETIRED? SAFETY ISSUES |
|
what kind of labs would we be looking for with TIAs?
|
lipid count
platlets for clotting factors we want a complete blood count a glucose level bleeding time (clotting factors) |
|
we do a blood glucose and its normal what then?
I mean the symptoms are like hypoglycemia and passed out |
it isn't diabetes related to the episode so it could of been a TIA
but we need to rule out low blood sugar. |
|
what does diabetes or hi blood sugar have to do with TIA so what does hi blood sugar and clotting have to do w/ this?
|
sticky blood! RBCs are sticky
they may do a cerebrial angiography (angiogram) watch how die profuses thru the brain if they throw one clot it can happen again so where would we look? in the lungs? Ausculate for anxiety from decreased oxyngenation? get an IV started? for immediate IV access! |
|
so we have the pt in front of us we need serial neurological exams to establish ...
|
a basline
tests like PERRLA vital signs neuro ck 12 cranial nerves for fields of vision |
|
why would a md put a pt on ace inhibitors?
|
its a anti hypertensive med
it dialates vascular system |
|
pt will be put on anticoagulants
put on antihypertensives ... what are some nursing Dx? |
ineffecive coping "i just had a little fall, im ok now"
fall risks knowledge deficit is a biggy |
|
so MD might order a carotid Endarterectomy what is this
|
rooter router surgery to remove plaque. its dangerous so they put it off to last b/c it can cause a stroke
|
|
what would be complications from a Carotid Endarterectomy?
|
stroke
cranial nerve injury infection hematoma of wound carotid artery disruption |
|
so the nurse management part
we will: close cardiac monitoring (ask if there is a Hx of coronary artery disease) ck their tongue...why? |
hypoglossal nerve & swallowing
cking the cranial nerves ...remember A&P |
|
the risk factors for this TIA stroke are like:
hypertension in blacks hi cloresterol & hi triglyerides aging any disease process what else? |
diabetes
cardiovasular Dx obesity elevated hematocrit 0ral contraceptives alcohol use |
|
ischemic something w/ a stroke
ischemic is kind of like hypoxia but instead of lack of o2 to tissue it means ... |
total blockage or a lack of blood flow to an organ. this can happen from TIA.Ischemica results from a thrombus (clot) in a blood vessel in the brain or cerebral embolism (a clot of stuff like air or fat
Ischemia to the brain is an arterial spasm that diesn't release |
|
what is multi infarct dementia?
|
from lots of small strokes which cause severe damage over time causing dementia
symptoms are: HALLUCINATIONS LIKE SIGHT,HEARING,FEELING ON THE SKINOR SMELL |
|
there is hemorrhagic in a stroke
results from: |
a rupture of a cerebral blood vessel w/ bleeding into the brain tissue or spaces around there
|
|
hemorrhagic strokes:
bleeding in the epidural or subarachnoid or intracerebrally where is this bleeding in the epidural? |
b/t dura mater & skull &
b/t periosteum & dura |
|
hemorrhagic stroke in the subdural hemorrahge
bleeding b/t dura matter & arachnoid membrane subdural is like a edidural except involves a brigding .. |
vein is torn

hemmorrhage strokes
intracerebral hemmorrhage is ... |
