A nurse is planning a community health program about Parkinson's disease. Which of the following interventions should the nurse include as a tertiary prevention strategy?

Rationale: A. Educate clients who are at risk for Parkinson's disease about maintaining a low-cholesterol diet: This is an example of primary prevention, aimed at reducing risk factors before the onset of disease, rather than tertiary prevention. B. Provide daily exercise classes to improve ambulation for patients who have Parkinson's disease: Tertiary prevention focuses on managing disease, minimizing complications, and improving quality of life for those already diagnosed. Exercise programs help maintain mobility and prevent further functional decline. C. Educate clients about common techniques used to diagnose Parkinson's disease: Teaching about diagnostic techniques is related to secondary prevention, which focuses on early detection and timely intervention. D. Provide screenings for community members to identify early manifestations of Parkinson's disease: Screening is a secondary prevention strategy intended to detect disease early in asymptomatic individuals, not tertiary prevention.
