Stroke Flashcards
Cranial Nerve II
Optic
Visual Acuity (Sensory) Ask pt to read Snellen's chart about 20 ft away. Close one eye at a time.
Cranial Nerve III
Oculomotor
Pupillary Constriction (Motor) Assess ocular movements and pupil reaction. PERRLA
Cranial Nerve IV
Trochlear
Vertical Eye Movement (Motor)
Ask pt to move eyeballs up and down
Cranial Nerve V
Trigeminal
Face Sensation (Sensory)
Light touch, wipe forehead, cheeks, and chin with cotton (eyes closed)
Mastication Muscles (Motor)
Palpate temporal and masseter muscles as pt clences teeth
Cranial Nerve VI
Abducens
Horizontal eye movement (motor)
ask pt to move eyeballs laterally
Cranial Nerve VII
Facial
Taste (sensory) Facial Expression (Motor) Ask pt to do facial expressions like smile, frown, raise eyebrows
Cranial Nerve IX
Glossopharyngeal
Taste (Sensory)
Gag Reflex (Motor)
Depress tongue, pt says “ahhhh” uvula and soft palate should rise to midline
Cranial Nerve X
Vagus
Pharynx and Larynx (Motor)
Ask pt to swallow, assess speech for hoarseness
Cranial Nerve XII
Hypoglossal
Movement of tongue (Motor)
Inspect the tongue
Frontal Lobe Function
- behavior/emotions
- planning/problem solving
- thinking/concentration
- expressive speech (Broca’s Area - if damaged they can understand but not speak)
- body movement
Parietal Lobe Function
- Senses (touch, pain, temp)
- Interprets signals (vision, hearing, motor)
- Interprets languages & words
Temporal Lobe Function
- Hearing
- Memory
- Understand language (Wernicke’s Area - damaged cannot understand speech and does not make sense)
Occipital Lobe Function
- Interprets vision (color, light, movement)
Left Side Functions
- Logical side
- Dominant side
- Speaking/language
- Reading
- Writing
- Math
- Analysis
- Planning
Right Side Functions
- Creative side
- Creativity
- Imagination
- Music Awareness
- Showing emotions
- Art awareness
Ischemic Stroke
- Usually due to a blocked artery (often by a blood clot)
- Brain cells do not receive enough oxygen/glucose and can soon die
Causes: Embolism (clot forms in body and travels to brain) or Thrombosis (clot forms in the artery in neck or brain)
Hemorrhagic Stroke
- Due to bleeding blood vessel in and around the brain
- Blood vessel ruptures, blood leaks into brain tissue or around the brain (decreased blood to brain cells, and increased swelling in brain)
Causes: Rupture of brain aneurysm, uncontrolled HTN, or age of blood vessels.
Transient Ischemic Attack (TIA)
- Early warning sign of impending stroke
- Caused by brief interruption of the blood supply of the brain
- Blood supply restored quickly, no tissue dies, brain function returns quickly
Microemboli
Sympathetic Nervous System
Eyes: dilates pupils
Salivary glands: inhibits saliva production
Lung: dilates bronchi
Heart: HR, muscle contraction increase
Adrenal gland: stimulates epi and norepi
Liver: stimulates glucose release
Kidney: inhibits urine secretion
Digestive: inhibits peristalsis & pancreatic secretion
Bladder: inhibits urination
Parasympathetic Nervous System
Eyes: constricts pupils
Salivary glands: stimulates saliva production
Lung: constricts bronchi
Heart: HR, and muscle contraction decrease
Kidney: stimulates urine secretion
Digestive tract: stimulates peristalsis & promotes pancreatic secretion
Bladder: stimulates urination
Genitalia: promotes erection
ACETLYCHOLINE
Prepocedure Lumbar
Vital signs notify HCP for increased ICP Place pt in side lying position have pt void educate pt on procedure may feel temporary sharp pain radiating down the leg
Postprecedure Lumbar
Monitor for headache and drainage
Teach pt to report numbness, tingling, and movement of extremities
FAST
Facial droop
Arm weakness
Speech
Time
Intracerebral Hemorrhage Manifestations
Severe headache with nausea and vomit
Decreased LOC
Hypertension
