miosis
constriction of pupils
dysphagia
difficulty in swallowing.
GBS assessment
Parsthesias, hypersensitivity, ascedning, weakness lower extremites first, possible resp. failure, CSF show elevated protien
Decerebate posture
abnormal extensionbrainstem lesion
# of Cervical vertebrae
7
rhinorrhea
("runny nose") or congestion
GBS interventions
treatment of symptoms/painmonitor RRgive RR treatments/support
Aphasia
Disordered or absent language function
Dysphasia
Impairment of express, comprehension, or both
ICP monitoring
 
 
Ventriculostomy-monitor and drain CSF if needed
Subarachnoid screw
Subdural/Epidural Catheter
Intraparenchymal of a Fiberoptic Transducer Tipped Catheter
Pricipal Motor Pathways
corticospinal (pyramidal) tractbasal gangia systemcerebellar system
Cheyne-Stokes Respirations
Rythmic, with periods of apneaIndicate: dysfunction in cerebral hemisphere or basal gangli
Lethargy
Able to elicit a response. Indifferent, apathetic, sluggish.
autonomic dysreflexia
an exaggerated sumpathetic response that occurs in clients with T-6 injuries or above; response is seen after spinal schock occurs when stimuli cannot ascend the cord, a stimulus such as urge to void or abdominal discomfort triggers massive vasoconstriction below injury, vasodilation above injury, and bradycardia
atrophy
degeneration, decline, or decrease, as from disuse
ipsilateral
pertaining to, situated on, or affecting the same side of the body:
Signs of Increased ICP
Decrease LOC (earliest indication)Abnormal respirationsIncrease BP and wide pulse pressureSlow pulsefevervomit/ pupil changes
Cerebrum
governs sensory and motor activity and thought and learning
Wernicke's area
section of temporal lobe responsible for primary auditory reception area and auditory association areas of speech
apraxia
a disorder of the nervous system, characterized by an inability to perform purposeful movements, but not accompanied by a loss of sensory function or paralysis.
contralateral
(of the body) pertaining to, situated on, or coordinated with the opposite side.
Epidural Hematoma
Between skull and dura
10% of severe head injuries
Usually associated with skull fractures
Injury to cerebral blood vessels under fracture
Bleeding continues and clot forms, seperating skull from dura.
Peripheral nerves
each nerve has an anterior (ventral) root containing motor fibers and a posterior (dorsal) root containing sensory fibersanterior and posterior roots merge to form a short spinal nerve, less then 5mm long
MRI Interventions
remove all metal, iv pumps, pulse oxclaustrophobic
Cranial Nerve XII
Hypoglossal - articulation: stick out tongue
Cranial Nerve II
Optic - Sight: Snellen Chart test
decerebrate
a person who, because of brain injury, exhibits behavior characteristic of a decerebrated animal.
Hypotension and brain injury
BAD! Often associated with bad outcomes.
Avoid!
Maintain MAP.
Avoid hypotonic fluids.

tension headache
caused by stress and tension; lasts > 4 hrs.; characterized by neck and shoulder muscle tenderness and bilateral pain at the base of the skull and in the forehead.
lower motor neurons
have cell bodies in the spinal cord (anterior horn cells)their axons transmit impulses through the anterior roots and spinal nerves, into peripheral nerves, terminating at the neuromuscular junction
hemianopsia
loss of half of visual field in one or both eyes
6 Steps of Neuro Assessment
1. mental status 2. cranial nerves 3. motor system 4. cerebellar function 5. sensory system 6. reflexes
