Q

the 2 vert arteries form the ___ A

A

basilar

21
Q

the ACA supplies the

A

medial and front side of the cortex

22
Q

TPA only works for __ stroke

A

ischemic (within 3 hours)

23
Q

angiogram is good for what conditions

A

anuerysm and AVN

24
Q

US is good for detecting

A

plaque in car A

25
Q

LOC is sx of what type of stroke

A

intracerebral hemorrhagic

26
Q

H/A, N/V, and decrease LOC is sx of what type of stroke

A

SA hemorrhagic

27
Q

with INR, if INR is low their chance of clotting is ___

A

high

28
Q

what can mimic a stroke

A

low BS

29
Q

ACA/MCA strokes are often from plaque forming in the

A

carotid arteries

30
Q

best choice for hemorrhagic stroke (imaging)

A

CT

31
Q

many small strokes deep in the white matter. usually only with the elderly. gray matter shrinks

A

multi infarct dementia

32
Q

best imaging choice for ischemic stroke

A

MRI

33
Q

why isn’t CT a good choice for ischemic stroke

A

they take days to show effects

34
Q

thrombolysis

A

break down of a clot with tPA (tissue plasminogen activator)

35
Q

components of the ICF

A

body structure and function (body part and deficit of body part)

activity (movement of body part needed for activity)

participation (the actual event they participate in - hobbies - job)

36
Q

what does Ca+ do during a stroke

A 
initial arrest
infarct
release of NT
altered metabolism
Ca increase which leads to edema which increases pressure which increases free radicals
37
Q

penundra

A

area around stroke

38
Q

where/what is most effected with ACA stroke

A

contralateral hemiparesis with sensory loss

LE most effected

behavior and personality most effected

39
Q

what is most effected with MCA stroke

A

contralateral hemiparesis

UE most effected

speech/language effected

40
Q

if I were to say right hemipareses, what is that considered

A

L sided stroke (meaning right side body issues)

41
Q

left hemiparesis means

A

left sided body issues (stroke occured on right side of brain)

42
Q

MASSIVE infarct of MCA (maybe ACA) that causes edema with herniation, coma or death

A

internal carotid artery syndrome

43
Q

PCA syndrome

A

minimal deficit usually sx depend on location

sx include: sensory loss, thalmic px, homonomous heminopsia, agnosia

44
Q

Lacuna strokes are often assct. with

A

HTN

45
Q

what is locked in syndrome

A

vertebrobasilar stroke that only eyes work/move

46
Q

agnosia means

A

inability to recognize/identify items

47
Q

thalmic px is associated with

A

PCA Stroke

48
Q

what often is the cause or precursor to an embolus

A

atrial fib that causes stagnant blood

49
Q

locked in syndrome is due to a stroke of the

A

vertebral basilar artery
