Supratentorial processes reduce arousal by:
displacement of the brain stem
An individual shows flexion in upper extremities and extension in lower extremities. This is
permits normal internal homeostasis
Percipitating causes of seizure include all of the following except:
Which epileptic seizure is characterized by temporal lobe spikes in teh EEG?
Postictal sleeping can be in :
grand mal seizures
is most prevalent as late onset dementia
abnormal posture maintained by muscular contractions
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?
Infratentorial heriation occurs with:
shifting of the mesencephalon
shifting of the diencephalon
In cerebral vasogenic edema:
plasma proteins leak into extracellular spaces
Which statement is not true regarding increasing intracranial pressures?
Accumulating CO2 causes vasoconstriction
Intellectual function is impaired in teh dementing process. Which intelllectual function is not impaired?
All are impaired functions:
Full Conciousness is :
an awareness of oneself and the enviroment with an ability to respond to external stimulu with a wide variety of responses
Cerebral Death results from:
permanent brain damage with an ability to maintain cardiac, respiratory and other vital functions
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.
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.
