Quiz 1 Flashcards
What is multiple sclerosis (MS)?
autoimmune disorder that affects nerve cells in the brain and the spinal cord
MS= myelin sheath destruction
Who is most likely to get multiple sclerosis?
young adults (20-50 years)
women
those w/ genetic disposition
Are there definitive diagnostic studies for MS? What can be done to see if it is MS?
no
MRI of brain can show sclerotic plaques in CNS
What is the criteria for an MS diagnosis?
- at least 2 inflammatory demyelinating lesions in at least 2 different CNS locations
- damage or an attack occurring at different times
- all other possible diagnoses ruled out
What are the clinical manifestations of multiple sclerosis?
weakness
diplopia (double vision)
tinnitus
paresthesia
chronic neuropathic pain
nystagmus (shaking of eyes)
dysphagia (difficulty swallowing)
ataxia (poor muscle control)
cognitive difficulties (word finding)
bowel/bladder problems
sexual dysfunction
depression
What immunosuppressants are given for MS? When is it given?
corticosteroids (prednisone, methylprednisolone, dexamethasone)
methylprednisolone: treats MS exacerbations
give in AM w/ food
What immunomodulators are used for MS? WHich one will treat/prevent relapses?
- interferon beta-1a and 1b: used to treat or prevent relapses
- glatiramer acetate
What antispasmodics are used for MS? Why?
Which one is given for severe symptoms and why?
- baclofen
- dantrolene
helps with spasms
dantrolene is used for severe symptoms bc it is fast acting
What is important to monitor with dantrolene with MS? What should be reported?
monitor liver damage
report jaundice
What antiseizures are used for MS? Why?
- carbamazepine
- gabapentin
used for paresthesia
What anticholinergics used for MS? Why?
- oxybutynin
- tolterodine
- propantheline
used for bladder dysfunction
What laxatives are used for MS? Why?
- stool softener (docusate sodium)
- bulk forming (psyllium)
used for constipation
What antidepressants are used for MS?
- amitriptyline (TCA helps w/ nerve pain)
- sertraline
- fluoxetine
What phosphodiesterase inhibitor is used for MS? What should not be given with this medication? Why?
Sildenafil
Do not give with nitroglycerin because it will decrease BP
What CNS stimulants are given for MS? What do they do?
- Methylphenidate (focus)
- Modafinil (alertness)
What K+ channel blocker is given for MS? Why is it not used as often?
Dalfampridine
Not used often due to risk of cardiac dysrhythmias
Why would a thalamotomy be used for MS?
It is deep brain stimulation for tremors unmanageable with drugs
What nursing interventions can be done with MS?
- promote exercise with rest/diet (fiber)
- encourage independence
- prevent injury, and avoid stressors
- teach self injection and self catheterization 
Describe Parkinson’s disease
Chronic neurological disorder that affects motor function and destroys neurons which results in low dopamine and high acetylcholine
No DOPE in the PARK = low dopamine in Parkinson’s
High acetylcholine = high secretions
Who is more likely to get Parkinson’s disease?
Men
What are the clinical manifestations of Parkinson’s disease?
Triad:
- Tremors at rest
- Rigidity
- Brady kinesia
Shuffling gait
Expressionless
Drooling/slurred speech (dysarthria)
Pill rolling twitch
Depression
Constipation
What are complications of Parkinson’s disease?
Dysphasia
Orthostatic hypotension (dopamine regulates BP)
