Assessment For S&S of CVA Flashcards
Autonomic status includes ?
BP, HR, RR, temp
Assessing S&S of a CVA
- ) assessment of patients autonomic status, including LOC.
- ) Assess sensorimotor status: Above & below shoulders.
- ) Assess reflexes
LOC includes ?
Alert / easily arousable to alertness if asleep.
Oriented x 4 = self, time, place, & events
Follows commands appropriately
Normal speech
Converses apropriately
Spectrum of severity can measure what ?
Spectrum of severity
Assessment of sensorimotor above the shoulders includes what ?
Eyes, face, tongue, and some shoulder functions.
If patient responds ok, then know that the 12 cranial nerves are intact.
Cranial nerves branch out from (midbrain, pons, & medulla) to the face, neck, upper chest & shoulders ON THE SAME SIDE OF THE BODY AS THEIR ORIGIN IN THE BRAIN. This is also know as what ?
IPSILATERAL SIDE
Right side CN compromised, expect to see what ?
Right side deficits of the face or above the shoulders.
Corticospinal tracts AKA pyramidal tracts are descending motor tracts that cross over from their point of origin in the cerebral cortex to the opposite side of the BODY at the junction between the spinal cord and the brain stem. Crossing over looks like a rypamid, this is know as what specific term ?
Decussate
Pyramidal tracts
Produce voluntary motor movements of purpose and skill
Lesion
General term that could be describing; a tumor, ischemia, localized ICP or increased cerebral edema.
Spinothalmic tracts
Ascending tracts that carry sensations of pain, temperature, and crude & light touch. They also cross from one side of the body to the other side of the brain .
Focal lesion on corticospinal or spinothalmic tracts expect to see what ?
Asymmetric senserimotor changes. Unilateral, on the contralateral side of the body because of decussation. Ex: right side brain tumor = deficits on the left side of the body.
Normal findings of peripheral reflex assessment suggests what ?
Suggest that there are good connections in the reflex arc of the spine. Therefore, a normal interpretation of the patients brain.
Normal central reflexes include what ?
Cough, swallow, gag
Explain a positive “BABINSKI REFLEX” AKA plantar reflex.
Stroke the plantar surface of the foot = Big toe flex, “upgoing toe”
Unilateral or Bilateral, depends if focal lesion or diffuse.
Normal until 2 years old, after that it is a sign of neurologic dysfunction of some sort.
Diffuse injury stroke S&S =
Sensation, muscle tone, movement, & strength: BILATERALLY WEAKER.
Weaker reflexes, sometimes + “Babinski” : SYMMETRICAL
Diffuse cerebral edema & IICP = what ?
Brain stem abnormalities, diminished LOC, usually comatose or near coma state.
Decerebrate or decorticate posturing that reflects the effect of cerebral edema on brain stem nuclei.
S&S of a patient with diffuse cerebral edema & IICP ?
- Cheyne-Strokes, changes in HR & BP due to: PRESSURE ON THE MEDULLA.
- Diminished or lost protective reflexes: Sneezing, coughing, gagging.
- HR problems due to involvement of the vagus nerve.
S&S of a CEREBELLAR CVA?
Problems with coordination and balance.
- vertigo, nystagmus (rapid eye movement)
- nausea & vomiting
- loss of coordination
- falling down
R or L side CVA that results from lack of blood flow OR bleeding leads to swelling and cerebral edema. What are 3 possible sets of deficits ?
*Lesion/pressure on :
certain area of the hemisphere = sensorimotor deficits
* corticospinal tract = sensorimotor deficits
*deficits based on that special functions controlled by that hemisphere.
What are you assessing for, if your assessment is focused above the shoulder ? Assessing the face, eyes, tongue, and some shoulder function ?
Cranial nerve function. Is there a lesion in a CN and/or in the cerebral brain tissue around it ? If the left side is not equal to the right side in sensation, tone, movement, & strenth, then we can consider a FOCAL PROBLEM WITH A CN.
Assessment below the shoulders. Is the left side equal to the right side in sensation, tone, movement, & strength ? If not, we may consider what ?
Focal lesion and/or edema where a corticospinal tract passes through that cerebral hemisphere.
