EXAM 1: Stroke questions with correct
answers
"rupture" stroke - correct answer ✔✔ hemorrhagic stroke
"occlusion" stroke - correct answer ✔✔ ischemic stroke
how fast does cellular death occur? - correct answer ✔✔ with decreased blood supply
decreases blood supply to cells.
occurs with COMPLETE lack of blood flow within 5 minutes
why is cerebral auto-regulation important? - correct answer ✔✔ the BP helps to regulate
pressure in the brain. we want bp elevated but not too high.
50-150 systolic bp to maintain blood flow
circle of willis - correct answer ✔✔ anterior cerebral artery, anterior communicating artery,
posterior communicating artery, middle cerebral artery
supplies blood flow to ALL arteries coming off the circle
helps to protect blood flow inside the brain
stroke Risk factors (non-modifiable) - correct answer ✔✔ age
,gender (males)
ethnicity (african american higher)
heredity
stroke Risk factors (modifiable) - correct answer ✔✔ HTN
DM
smoking
cholesterol
obesity
BCP (birth control pills) ***
ETOH
what is used to predict the probability of a stroke 2 days after a TIA? - correct answer ✔✔ the
ABCD scoring for risk assessment.
the higher the points the greater the risk
TIA (Transient ischemic attack) definition - correct answer ✔✔ micro-emboli that temporarily
BLOCKS blood flow to the brain.
small emboli that travels through circulatory system to the brain, when the vessel gets smaller it
gets stuck in the bifurcation.
S/S of TIA (Transient Ischemic Attack) - correct answer ✔✔ speech
, confusion
facial droop
one-sided weakness
tinnitus - ringing in ears**
dizziness
difficulty swallowing
s/s usually only last about an hour bc its an ATTACK, the clot might dissolve and blood flow will
return. ***
how to prevent further occurrences of a TIA stroke - correct answer ✔✔ treated with meds
change diet
exercise
med adherence (antiplatelet-aspirin, HTN meds, BS meds)
thrombotic is an example of what type of stroke - correct answer ✔✔ ischemic stroke
thrombotic: the process of clot formation (thrombosis) results in narrowing of the lumen, which
blocks the passage of blood through artery
