Unit 7 - Neuromuscular & Musculoskeletal Flashcards
(110 cards)
2 classifications of Parkinson’s
- idiopathic (no known cause)
2. Secondary (antipsychotic meds)
neurogenerative disease that has the best response to medications that we know
Parkinson’s
In Parkinson’s there is _____ dopamine being secreted and the little that is secreted is being broken down by ____
less
MAO
In Parkinson’s there is an imbalance of dopamine to acetylcholine causing…
decreased balance and coordination
What disease:
there is a drop in the amount of dopamine in the brain
Parkinson’s
2 causes of Parkinson’s
- # of nerve cells that produce dopamine is decreased
2. levels of MAO at the synapse remains unchanged
purpose to drugs used in treatment of Parkinson’s
help improve mobility and functioning in ADL’s
T/F: Parkinson’s patients will sometimes be prescribed both Dopamine Agonists & Anticholinergics
T
postural and autonomic movements
dyskinesias
4 types of dyskinesias
acute dystonia
akathisia
Parkinsonism
tardive dyskinesia
severe muscle spasms of the back, neck, tongue, & face
acute dystonia
inability to rest or relax, repetitive movements
akathisia
tremor, loss of fine motor skills, muscle rigidity, stooped posture, shuffling gate
Parkinsonism
involuntary and unusual tongue and facial movements; lip smacking, tongue thrusting, eye blinking
tardive dyskinesia
Extrapyramidal Symptoms (EPS)…is there treatment?
Dyskinesias
- no treatment for symptoms and they may last for years after therapy is discontinued
goal of antipsychotic meds
decrease dopamine
Drug of choice for Parkinson’s
Levodopa…precursor to dopamine
- crosses BBB
What drug: treat Parkinsonism; to relieve tremors & rigidity
Levodopa
Adverse effects of Levodopa
- adverse reactions associated with anticholinergic properties (dry mouth, blurred vision, urinary retention)
- spazzy dance movements (involuntary choreiform)
- psychosis because of increase dopamine
- quick jerking movements = need to get dosage lowered
Nursing Considerations for Levodopa
- monitor liver & kidney function (metabolism & excretion probs)
- monitor for adverse affects
- assist with ambulation
- assess for narrow-angle-glaucoma
9 Pt & Family teaching for Levodopa
- DO NOT abruptly stop taking-NMS
- do not crush/chew
- report s/s of toxicity: twitching, winking, mood changes
- make position changes slowly
- increase fiber in diet
- avoid foods high in protein & B-6
- understand affects may take several months
- may have darkening of urine/sweat
- can take other meds to help with N,V
life threatening, potentially fatal adverse reactions (like having extreme Parkinson’s)
NMS - neuroleptic malignant syndrome
5 symptoms of NMS
- muscle rigidity
- tachycardia
- BP fluctuations
- high fever
- diaphoresis
T/F: NMS is rare & and be fatal
