  1. CVAs or ___ involve a disruption in the cerebral blood flow secondary to what 3 things?
    • stroke
    • ischemia
    • hemorrhage
    • embolism
  2. List the 3 causes of CVAs.
    • hemorrhagic
    • thrombotic
    • embolic
  3. Hemorrhagic CVAs occur secondary to what?
    ruptured artery or aneurysm
  4. T/F Prognosis for hemorrhagic CVA is fair.
    F; poor
  5. Thrombotic CVAs occur secondary to what?
    development of blood clot on atherosclerotic plaque in cerebral artery that gradually shuts off artery and causes ischemia distal to occlusion
  6. Symptoms of a ___ CVA evolve over a period of several hours to days.
  7. Embolic CVAs occur secondary to what?
    embolus traveling from another part of body to cerebral artery
  8. With this cause of CVA, blood to the brain distal to occlusion is immediately shut off causing neuro deficits or loss of consciousness to instantly occur.
  9. An embolic CVA is very sensitive b/c many can be reversed if antiembolic meds such as ___ are administered w/in ___ to ___ hours of initial symptoms.
    • alteplase (Activase, tPA)

  10. List 3 things that can increase CVA risk.
    • HTN
    • diabetes mellitus
    • smoking
  11. T/F Maintaining a healthy wt and getting regular exercise can decrease risk of CVA.
  12. Besides diabetes mellitus, obesity, HTN, atherosclerosis, hyperlipidemia, and smoking, list 6 additional risk factors for CVA.
