With Accurate Solutions
describe the pathogenesis of an embolic stroke - ANSWER-fragments formed outside of
the brain break off and travel to the brain
sudden onset
what population is associated with "Lacunes" penetrating artery disease? - ANSWER-
associated with chronic HTN and DM
elderly
small areas of infarction
higher cortical areas are preserved, there is no LOC, language, or visual defects
what three factors determine the severity of neurological defects after a stroke? -
ANSWER-location and extent of the injury, amount of collateral blood flow, and early
acute care management
the severity and symptoms of stroke are dependent on a number of factors, including: -
ANSWER-location of the ischemic process, size of the ischemic area, the nature and
functions of the structures involved, availability of collateral blood flow
slow occlusions may allow for collateral blood to take over, while sudden events do not.
describe the pathogenesis of a thrombotic stroke - ANSWER-vessel occlusion/ platelet
aggregation
gradual onset, often during sleep when BP is low
,what are risk factors for an embolic stroke? - ANSWER-atrial fibrillation, endocarditis,
valve disease, CABG, patent foramen ovale
what would explain impairments after a stroke resolving spontaneously after about 3
weeks? - ANSWER-brain swelling subsides
residual neurological impairments are those that last longer than 3 weeks/ after brain
swelling goes down, and may lead to lasting disability
what is the difference between a major stroke and a deteriorating stroke? - ANSWER-a
major stroke is stable, usually with severe impairments
a deteriorating stroke is when neurological status changes in a negative direction after
admission to the hospital (may be due to cerebral or systemic issues - such as cerebral
edema or a progressing thrombosis)
What ICF category does the Fugl-Meyer Assessment of Physical performance look at? -
ANSWER-body structure and function
stroke specific, impairment based test
what ICF category does the Wolf Motor Function Test look at? - ANSWER-activity
limitations
stroke specific
what ICF category does the Stroke Impact scale look at? - ANSWER-activity and
participation restrictions
, it is stroke specific, self report measure developed to assess function and QOL after
stroke.
assesses strength, memory/thinking, emotions, communication, ADL, mobility, hand
function
what is the FIM? - ANSWER-functional independence measure
categories of helper/ no helper
activity focused
measure of physical, psychological, and social function
uses level of assistance a patient needs to grade functional status from total
independence to total assistance.
measures what the patient does, not what they could do under certain circumstances
survival rates for stroke are dramatically lessen by what factors? - ANSWER-increased
age, hypertension, heart disease, and DM
what are important predictors of mortality of stroke? - ANSWER-loss of conciousness at
stroke onset, lesion size, persistent severe hemiplegia, multiple neurological deficits,
history of previous stroke
what are the most common sites for atherosclerotic plaques to occur? - ANSWER-origin
of the common carotid
transition of the carotid to the MCA
main bifurcaion of the MCA
junction of vertebral arteries to the basilar artery
