Practice Question
A nurse is assessing a client with Parkinson's disease. Which of the following findings are characteristic extrapyramidal symptoms associated with this condition?
Answer Choices:
Correct Answer:
Resting tremor that decreases with intentional activity
Rationale:
🧩Parkinson’s disease produces a resting, “pill-rolling” tremor (≈4–6 Hz) that lessens with voluntary movement and reappears at rest, a hallmark extrapyramidal sign.
🧩Pathophysiology centers on dopamine depletion in the substantia nigra pars compacta, disrupting basal ganglia circuits (direct/indirect pathways) that modulate motor output.
🧩The classic triad includes tremor, rigidity (cogwheel/lead-pipe), and bradykinesia, often with postural instability as disease advances.
🧩Tremor reduction during action reflects compensatory cortical control overriding basal ganglia dysfunction, contrasting with action/intention tremors seen in cerebellar disease.
🧩Recognition of this pattern guides therapy with levodopa/carbidopa, dopamine agonists, or deep brain stimulation targeting the STN/GPi.
