Final answer:
The most consistent findings in a person with Parkinson's disease are tremor at rest and bradykinesia. Parkinson's is characterized by the loss of dopamine releasing neurons in the substantia nigra, leading to the primary motor symptoms of tremor, rigidity, and slowed movement.
Step-by-step explanation:
Which of the following is most consistent with findings in a person with Parkinson's disease? The answer is c) Tremor at rest and bradykinesia. Parkinson's disease is a degenerative disorder of the central nervous system, primarily affecting the muscular system and movement. Four motor signs and symptoms define this disease: tremor at rest (most common and obvious symptom), muscle rigidity, slowness of movement (bradykinesia), and postural instability. As the disease progresses, difficulties with walking develop, and symptoms like depression and cognitive issues such as dementia become more common. Parkinson's disease is caused by the degeneration of neurons that release dopamine, particularly in the substantia nigra, a part of the midbrain that regulates movement.
