    Breathing pattern expected with damage to the pons or upper medulla oblongata
  10. What is compliance?
    Increase in one component of the cranium is offset by reducing the volume of one of the other components

    Profound headache,photophobia & stiff neck prior to rupture
  13. What causes double vision after a basilar artery stroke?
    Impairment of cranial nerves III, IV, and VI after a basilar artery stroke
  14. What is the pathophysiology of diffuse brain injury?
    All brain cells fire at once releasing glutamate and triggering release of potassium

    After shining a light into the eyes, both pupils are dilated
  25. What is the pathogenesis of seizures?
    Excessive and autonomous firing of cerebral neurons
  26. What is the pathogenesis of Parkinson disease?
    Dopamine from substantia nigra in the basal ganglia is depleted
  27. What is meningomyelocele?
    Sac-like structure protrudes thru a vertebral defect containing meninges, spinal cord, and CSF

    Inflammatory demyelinating disease of the peripheral nervous system
  29. What are manifestations of Guillain Barre?
    Progressive ascending paralysis beginning in the legs,may involve respiratory muscles
  30. What is the pathophysiology of multiple sclerosis?
    Autoimmune disorder in which myelin in central nervous system is destroyed.
  31. What are manifestations of Parkinson disease?
    Bradykinesia, rigidity, resting tremor , and masked facies with no change in consciousness
  32. What is an absence seizure?
    A seizures in which the client has a short lapse of consciousness (about 5 - 10 sec)
  33. What is a tonic-clonic seizure?
    A seizure in which there is loss of consciousness withbody stiffness alternating with muscle spasms
  34. What are manifestations of spastic cerebral palsy?
    Hypertonic and exaggerated deep tendon reflexes seen in children
  35. What are manifestations of multiple sclerosis?
    Manifestations are highly variable from visual impairment to paralysis with fatigue being a common one.
  36. What are manifestations of Bell’s palsy?
    Unilateral facial weakness, facial droop and diminished eye blink
  37. What is Bell’s palsy?
    Paralysis or paresis of the 7th cranial nerve (facial)
  38. What occurs in the secondary cascade of spinal cord injury?
    Hemorrhage and edema result ischemia and necrosis of the spinal cord.
  39. What is a definition of hydrocephalus?
    Abnormal accumulation of cerebrospinal fluid in the subarachnoid space
  40. What is status epilepticus?
    One seizure after another without a period of recovery
  41. What is a characteristic of a partial seizure?
    Seizure activity that is restricted to one hemisphere
  42. What is the cause of obstructive hydrocephalus?
    Impaired flow of cerebrospinal fluid between the 3rd and 4th ventricles.
  43. What are manifestations of spinal shock after spinal cord injury?
    Flaccid paralysis,anesthesia below injury level, transient drop in BP
  44. What are manifestations of a lumbar herniated nucleus pulposus
    Pain radiates along the sciatic nerve when client coughs or sneezes
  45. What is the pathogenesis of myasthenia gravis?
    Destruction of acetylcholine receptors by an autoimmune process
  46. What is a cause of autonomic dysreflexia (hyperreflexia)?
