neurologic disorder 2 Flashcards
Inflammation of brain tissue caused by virus
Encephalitis
Signs and symptoms Encephalitis
Fever, nuchal rigidity (stiff neck), headache, confusion, delirium, agitation, and restlessness commonly seen
Comatose or exhibit aphasia, hemiparesis, facial weakness, and other alterations in motor activity
Medical treatment Encephalitis
Enhance patient comfort and increase strength
Because seizure activity is a potential problem, take appropriate safety precautions
Nursing Care
Encephalitis
The nursing plan of care parallels that of the patient with meningitis
Although specific cause unknown, it is believed to be an autoimmune response to a viral infection
Patients often report some recent viral infection or vaccination
Guillain-Barré Syndrome
Initial phase s/s Guillain-Barré Syndrome
Symmetric muscle weakness: begins in lower extremities; ascends to trunk and upper extremities
Visual and hearing disturbances, difficulty chewing, and lack of facial expression
Mild paresthesias or anesthesia in feet and hands in a glove or stocking distribution pattern
Hypertension, orthostatic hypotension, cardiac dysrhythmias, profuse sweating, paralytic ileus, and urinary retention
Plateau phase s/s Guillain-Barré Syndrome
Remains essentially unchanged
No further neurologic deterioration, but no improvement either
Recovery phase s/s Guillain-Barré Syndrome
Remyelinization; muscle strength returns in a proximal-to-distal pattern (head to toes
medical diagnosis Guillain-Barré Syndrome
Characteristic onset and pattern of ascending motor involvement
Elevated protein level in the CSF
Nerve conduction velocity studies reveal slowed conduction speed in the involved nerves
medical treatment Guillain-Barré Syndrome
Preserve vital function, particularly respiration
Respiratory status is closely monitored and mechanical ventilation initiated if vital capacity falls to 15 mL/kg of body weight
Massive doses of corticosteroids prescribed to suppress the inflammatory process
Plasmapheresis
assessment of Guillain-Barré Syndrome
Health history describes the progression of symptoms
Note fears, coping strategies, and sources of support
Physical examination focuses on cranial nerve, motor, respiratory, and cardiovascular function
Progressive degenerative disorder of the basal ganglia: an eventual loss of coordination and control over involuntary motor movement
Parkinson’s Syndrome
Parkinson’s Syndrome s/s
Tremor, rigidity, and bradykinesia
Loss of dexterity and power in affected limbs, aching, monotone voice, handwriting changes, drooling, lack of facial expression, rhythmic head nodding, reduced blinking, and slumped posture
Depression common; dementia may develop
Medical diagnosis Parkinson’s Syndrome
From health history and physical examination
MRI to rule out other causes of the symptoms
Medical treatment Parkinson’s Syndrome
Control symptoms: physical therapy and drug therapy
Massage, heat, exercise, and gait retraining
Dopamine receptor agonists pramipexole (Mirapex) or ropinirole (Requip); L-dopa (L-dihydroxyphenylalanine); carbidopa/levodopa (Sinemet); anticholinergic drugs such as trihexyphenidyl (Artane) and benztropine (Cogentin)
