16
Q

TIA

A

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

17
Q

stroke protocol

A
ct done in 25 minutes or less
MRI 
determine if stroke is hemorrhagic or ischemic 
id source 
ekg 
doppler studies
18
Q

prevent stroke

A

treat peridontal diseases

carotid endartectomy

19
Q

acute phase of a stroke

A

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
Q

contraindications for tPa

A

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

21
Q

managment of patient not receiving Tpa

A
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
Q

CEA

A

better with older people

younger people do better with stenting

23
Q

nursing process and care

A

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
Q

signs and symptoms of a hemorrhagic stroke

A
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
31
after the stroke
aspiration assistive devices for ADLs nutritional support (tube feeds or swallowing techniques) elimination of bowel and bladder programs, catheter use exercise activities, recreation and diversion socailization, support groups, community resources
32
hemiplegia
paralysis on one side of the body
33
hemiparesis
slight paralysis or weakness on side of the body
34
dysarthria
difficulty speaking
35
aphasia
expressive receptive unable to understand written or spoken language global expressive and receptive aphasia
36
hemianopsia
blindness in over half the field of vision
37
effects of sugar on the brain
hypoglycemia: fatigue, shaking, confusion or unresponsiveness, insomnia hyperglycemia: headache, trouble concentrating, blurred vision
