How does the immune system affect GB? - CORRECT ANSWER: Stimulating organism
causes an alteration in immune system, resulting in sensitization of t-lymphocytes to
myelin causing myelin damage.
Demyelinization causes slowing or stopping of nerve impulses resulting in muscle
denervation and atrophy
demyelination occurs proximal to distal
How is a brain abscess treated? - CORRECT ANSWER: antimicrobial therapy and/or an
I&D
How is ALS diagnosed? - CORRECT ANSWER: R/O other neurological diseases,
muscle biopsy, electromyogram
How is encephalitis treated? - CORRECT ANSWER: symptomatic & supportive
approach;
-HSV antivirals: acycolvir & Vira-A
-antiseizure meds
-Mannitol & Decadron for cerebral edema
How is GB diagnosed? - CORRECT ANSWER: EMG, LP showing protein >700mg/dl
,How is MG diagnosed? - CORRECT ANSWER: Tensilon test (blocks
acetylcholinesterase), when used in a pt with MG muscle contractility is improved
How is MS treated? - CORRECT ANSWER: no cure, drug therapy for symptoms
What antibiotics are used to treat bacterial meningitis? - CORRECT ANSWER:
ampicillin, vancomycin, & Ceptaz
What anticholinergic is used for MS? - CORRECT ANSWER: Ditropan- treats urinary
frequency, C/I glaucoma;
check with MD before taking antihistamines, can potentiate
What anticholinergics are used to treat Parkinsons? - CORRECT ANSWER: Artane,
benzotropine
relieves tremors
A/E- dry mouth & blurred vision
no OTC antihistamines, assess for anxiety & agitation
What antihistamines are used to treat Parkinsons? - CORRECT ANSWER: Benadryl
relieves tremors & rigidity
A/E- dry mouth & blurred vision
assess for sedation
What antiparkinsons med is used for MS? - CORRECT ANSWER: symmetrel; helps
with fatigue
may caused blurred vision, confusion, SOB- avoid alcohol
What are clinical manifestations of MG? - CORRECT ANSWER: weakness of eyelid &
ocular muscles
, trouble breathing, swallowing, & with speech
weakness of muscles and limbs
What are common side effects of seizure medications? - CORRECT ANSWER: diplopia,
drowsiness, ataxia, slowness
What are hallmark signs of MG? - CORRECT ANSWER: -muscle strength is restored
after rest
-promixal muscles are affected more than distal
-no senses are lost & reflexes are normal
-exacerbations are brought on by stressors
What are signs of a anticholinergic crisis? - CORRECT ANSWER: brought on by
overmedication for MG;
abdominal cramping, diarrhea,diaphoresis,constricted pupils, increased salivation
treatment- stop meds,suction as needed
What are signs of a myasthenic crisis? - CORRECT ANSWER: brought on by
undermedication for MG;
ocular sx, increased weakness, resipratory infection, aspiration, respiratory muscle
failure
treatment: IV anticholinergics, corticosteriods, plasma exchange
What are the causes of a seizure? - CORRECT ANSWER: Acidosis, electrolyte
imbalances, hypoglycemia, hypoxia, alcohol and drug withdrawal, dehydration, water
intoxication, organ disease, SLE, DM, HTN, septicemia OR may occur idopathically
What are the causes of epilepsy? - CORRECT ANSWER: Birth injury, congenital CNS
defects, infection, trauma, genetic errors, drug overdose, metabolic alterations, brain
tumor, vascular disease OR may occur idiopathically
