Postural Instability

Question 5

Clients with Bradykinesia, tremors & rigidity that DO NOT RESPOND to Dopaminergic drugs are typically said to have ____________________

Answer 5

PARKINSONISM instead of Parkinsons Disease

Question 6

CLINICAL MANIFESTATIONS

associated with TREMORS

(5)

1. Early sign–typicallys begins with 1 hand, foot, etc.
2. more prominent when pt is at rest (declines with movement)
3. “PILL ROLLING”
4. Exacerbated by Stress /Anxiety
5. Progressive Difficulty with ADL’s

Question 7

bradykinesia

Answer 7

slow movements

Question 8

DIAGNOSTIC TESTING

for

PARKINSON DISEASE

(6)

Answer 8

• Presenting symptoms
• neurological exam
• response to medication ^{(favorable outcome to levodopa / carbidopa)}
• DaT Scan
• MRI
  
  • Client w/PD will have normal exam from MRI and/or CT scan
  • This will rule out other causes
• 2 of 4 TRAP CRITERIA

Question 9

DaT Scan

Answer 9

**identifies lack of dopamine receptors in the brain

1. Binds to dopamine transporters
2. *clients w/degeneration of dopamine will show less uptake^{**thyroid needsblocked before injection of radioactive dye to prevent thyroid accumulation}*

IT CAN: _{DIFFERENTIATE BETWEEN ESSENTIAL TREMORS & TREMORS R/T PARKINSONIAN SYNDROME.}

IT CAN NOT:_{differentiate between parkinson disease and other dopamine degenerative disorders}

Question 10

“5” stages of Parkinson’s Disease

Answer 10

STAGE 1: Shaking/tremor in 1 extremity STAGE 2: Bilateral extremities affected Walking/Balance Poor STAGE 3: Slowed Physical Movement Walking more affected STAGE 4: Akinesia & rigidity make ADL’s difficult STAGE 5: Unable to stand/Walk Dependent for all care

Question 11

What is

DEEP BRAIN STIMULATION?

Answer 11

**Electrode implanted in Thalmus

-Current delivered by small pulse generator implanted under the skin of upper chest

• Decreases Tremors
• Reduces rigidity
• Improved Akinesia
• Allows for decreased dose of Levodopa

Question 12

Define Dysarthria

Answer 12

Slurred or Slowed speech

Difficult to understand

Question 24

“2” Nursing considerations for Dopaminergic medications

Answer 24

1. monitor for “weaning off” phenomenon
2. Dyskinesias…….^{(which can indicate the need to adjust the dosage or time of administration)}
