1

agnosia

failure to recognize objects '

2

atrial venous malformation

theres no organization at the circle of willis

3

cryptogenic stroke

no one cause, could be drugs, coagulopathies, migraines, spontaneous dissections of coratid or vertebral arteries

4

every hour you stroke-

the brain is aging three and a half years

5

pathophysiology of a ischemic stroke

disruption in blood flow, aerobic respirations, acidosis, damage to the surrounding cells

6

pneumbra region

area around the body that is low as cerebral blood flow
can be salvaged
if left untreated the area of damage will increase and produce free radicals

7

clinical manifestations of an ischemic stroke

symptoms depend on location and size
numbness or weakness of face, arm, legs, especailly on one side
confusion
trouble speaking or understanding speech
difficulty walking, dizziness, loss of balance or coordination
sudden severe head ache
perceptual disturbances

8

the right side of the brain is

creative

9

left side of the brain is

analytic

10

average time of recovery

18 months

11

with a stroke people often have motor defects

opposite side of where the stroke is

12

aphasia

expressive
receptive
global

13

behavioral symptoms of a left side stroke

rt side paralysis
rt visual deficits
aphasia
altered intellect
slow cautious behavior

14

behavioral symptoms right sided stroke

paralysis and weakness on left side
visual deficits on left side
spatial awarness defecits
increased distractibility
impulsive behaviors and poor judgement
lack of awarness of deficits

15

general s/s of ischemic stroking

motor loss
communcation loss
sensory loss cognitive impairment
psychological effects

16

TIA

sudden neuro deficits lasting an hour, warning sign of an impending stroke
no ischemia/long term damage

17

stroke protocol

ct done in 25 minutes or less
MRI
determine if stroke is hemorrhagic or ischemic
id source
ekg
doppler studies

18

prevent stroke

treat peridontal diseases
carotid endartectomy

19

acute phase of a stroke

tPA with in 3 hours of stroke. improved outcome
maintain airway - o2 immediatly to vaso dilate
elevate hob to decrease icp
continous hemodynamic monitoring and neurologic assessment
2 18 gauge IV
no abgs
imaging competed in 25 minutes in ear
transfer to a higher level of care

20

contraindications for tPa

inr >1.7, recent cva, recent head injury or trauma

21

managment of patient not receiving Tpa

LMWH
monitor icp
mannitol
paco2 30-35hhmg
o2, hob 25-30 degres s
intubation and hemodynamic monitoring
icu support
surgical invention for CEA
edema causes death and decreased o2 can cause brainstem herniation

22

CEA

better with older people
younger people do better with stenting

23

nursing process and care

loc, neuro assessment, mobility, joint deformities, skin integrity, pressure ulcers, self-care, nutritional and bladder/bowel, cognition, family coping, splinting to position of function, wash clothes in hangs/ alignment
prevent flexion contractures, do not lift by flaccid shoulder, measures to prevent shoulder problems, passive rom 4-5 times a day
turm head to assist eith visual deficits
EXERCISE UNAFFECTED SIDE

24

signs and symptoms of a hemorrhagic stroke

sudden change in loc
n/v
severe head ache
brain stem involvement
loss of consciousness
nuchal rigidity
visual loss
diplopia
tinnitus
dizziness
hemiparesis
severe bleeding can cause damage that leads to rapid progression of symptomology which causes coma and death

25

complication of hemmorrhagic stroke

re bleed
hematoma expansion
cerebral vasospasm, ischemic event
acute hydrocephalus
seizures
H&H, IV hydration, vasospasm, icp, uncontrolled HTN is cause of intracranial hemorrhage, stool softeners to prevent and increase BP

26

medical managment

control of HTN
Ct scan, cerebral angiography, care is primarily supportive, bed rest with sedation, oxygen, tx of hyperglycemia, trx of vasospasm, increased ICP, HTN, potential seizures, prevention of further bleeding, avoid stress dont be rough

27

korsakoffs syndrome

psychosis and delirium

28

potential complication of ischemic stroke

vasospasm
seizures
hydrocephalus
rebleed
hyponatermia

29

aneurysm precautions

absolute bed rest
elevate HOB 30 degrees
avoid all activity that may increase ICP or BP
Valsalva manuver
acute flexion of the head or neck
exhale through mouth to decrease strain
nurse provides all personal care and hygiene
non stimulating, non stressful environment
no reading, no TV, no Radio, prevent constipation
restrict vistors

30

interventions

relieve sensory deprivation and anxiety
keep sensory stimulation to a minimum for aneurysm precautions
patient and family education
support reassurance
seizure precautions
strategies to regain and promote self care
