University of San Francisco - NURS 320

Chapter 04: Psychobiologic Bases of Behavior Keltner: Psychiatric Nursing, 8th Edition

MULTIPLE CHOICE

1)When a nurse administers medication that focuses on the management of Parkinson disease, what is the focus of the associated evaluation?

    1. Spinal nerve function
    2. The central nervous system
    3. The sympathetic nervous system
    4. The expected effects of dopamine

 

In Parkinson disease (PD), dopamine is reduced by death of dopamine releasing cells in the substantia nigra. Without the excitatory effect of dopamine to the striatum, more pallidal firing reduces thalamic activity. Cortical activating effects are reduced, with decline in initiating and executing motor activity, causing bradykinesia, and disinhibition of muscular control, causing resting tremor, rigidity, and loss of postural reflexes. Treatment efforts in PD are directed at resupplying dopamine to the CNS via L-DOPA, or providing dopamine antagonists. This drug therapy does not affect spinal nerve function or function associated with the central or sympathetic nervous systems.
