ch 57 stroke Flashcards
two types stroke
ischemic
hemorrhagic
stroke caused by clot within artery of brain
ischemic
type of ischemic stroke due to atherosclerosis
thrombotic
type of ischemic stroke due to clot from other part of body that travels to brain (ex: DVT)
embolic
risk factor for embolic stroke
Afib
S+S stroke that disappear within three hours
transient ischemic attack
treatment for transient ischemic attack
preventative aspirin
risk factor/cause hemorrhagic stroke
uncontrolled HTN

2 types aphasia
broca’s aphasia
wernicke’s aphasia
type of aphasia characterized by nonfluent, short phrases
broca’s aphasia
type of aphasia characterized by fluent speech that doesn’t make sense, impaired comprehension
wernicke’s aphasia
diagnosis for stroke (during and in recovery - 3 total)
-during: CT stat (w/o contrast)
AFTER:
-carotid ultrasound
-lipid panel
initial interventions (ER) for stroke (6)
- ensure patent airway
- SpO2 (give O2 if needed)
- IV
- head CT w/o contrast
- maintain good bp
- anticipate thrombolytic therapy
