The flashcards below were created by user adnap28 on FreezingBlue Flashcards. What would you like to do?


  1. Supratentorial processes reduce arousal by:
    displacement of the brain stem
  2. An individual shows flexion in upper extremities and extension in lower extremities. This is
    decorticate posturing
  3. Cerebral death
    permits normal internal homeostasis
  4. Percipitating causes of seizure include all of the following except:
    hyperglycemia
  5. Which epileptic seizure is characterized by temporal lobe spikes in teh EEG?
    psychomotor
  6. Postictal sleeping can be in :
    grand mal seizures
  7. Alzheimer disease:
    is most prevalent as late onset dementia
  8. Dystonia
    abnormal posture maintained by muscular contractions
  9. An individual with increased intracranial pressure from a head injury shows small and reactive pupils widened pulse pressure and slowed breathing. Which stage of ICP exists?
    Stage 3
  10. Infratentorial heriation occurs with:
    • shifting of the mesencephalon
    • shifting of the diencephalon
  11. In cerebral vasogenic edema:
    plasma proteins leak into extracellular spaces
  12. Which statement is not true regarding increasing intracranial pressures?
    Accumulating CO2 causes vasoconstriction
  13. Intellectual function is impaired in teh dementing process. Which intelllectual function is not impaired?
    • All are impaired functions:
    • anterograde memory
    • retrograde memory
    • abstraction
    • language deficits
  14. Full Conciousness is :
    an awareness of oneself and the enviroment with an ability to respond to external stimulu with a wide variety of responses
  15. Cerebral Death results from:
    permanent brain damage with an ability to maintain cardiac, respiratory and other vital functions
  16. What is a Seizure?
    represent a sudden and chaotic discharge of cerebral neurons with transient alterations in brain function. They may be generalized or focal and can result from cerebral lesions, biochemical disorders, trauma or eplilepsy.
  17. What is the result of increased intercranial pressure?
    it may result from edema, excess CSF, hemorrhage or tumor growth. When intracranial pressure approaches arterial pressure, hypoxia and hypercapnia produce brain damage.
