Answer to Question 1

Correct Answer: 4
Rationale 1: Parkinson disease is not caused by the death of neurons that produce acetylcholine.
Rationale 2: Parkinson disease is not caused by the death of neurons that produce serotonin.
Rationale 3: Parkinson disease is not caused by the death of neurons that produce norepinephrine.
Rationale 4: Symptoms of Parkinson disease develop due to the destruction of the dopamine-producing neurons located in the substantia nigra. These neurons supply dopamine to the corpus striatum, the region of the brain that controls unconscious muscle movement.
Global Rationale: Symptoms of Parkinson disease develop due to the destruction of the dopamine-producing neurons located in the substantia nigra. These neurons supply dopamine to the corpus striatum, the region of the brain that controls unconscious muscle movement. Parkinson disease is not caused by the death of neurons that produce acetylcholine, serotonin, or norepinephrine.

Answer to Question 2

Correct Answer: 1
Rationale 1: The classic symptoms of Parkinson disease are tremors, muscle rigidity, bradykinesia, and postural instability.
Rationale 2: Confusion is not a typical sign of Parkinson disease.
Rationale 3: Hyperkinesia is not a typical sign of Parkinson disease.
Rationale 4: Generalized muscle weakness is not a typical sign of Parkinson disease.
Global Rationale: The classic symptoms of Parkinson disease are tremors, muscle rigidity, bradykinesia, and postural instability. Confusion, hyperkinesias, and generalized muscle weakness are not typical signs of Parkinson disease.
