A nurse is reinforcing discharge teaching with the family of a client who has a new diagnosis of Parkinson's disease and a prescription for levodopa/carbidopa. Which of the following statements made by the client's family indicates an understanding of the teaching?

The correct answer is B: "We should watch for an increase in unusual movements." This statement indicates an understanding of the teaching because levodopa/carbidopa can cause dyskinesias or abnormal involuntary movements as a side effect. Monitoring for these movements is crucial to manage and adjust the medication dosage accordingly.
Incorrect choices:
A: Protein intake should be spaced out throughout the day to optimize levodopa absorption, not consumed in large amounts with each meal.
C: Levodopa/carbidopa helps manage symptoms but does not stop the progression of Parkinson's disease.
D: Improvement with levodopa/carbidopa is gradual and not rapid. Monitoring symptoms over time is necessary.
