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?

Tertiary prevention focuses on reducing disability and improving quality of life in those who already have a disease. Daily exercise classes to improve ambulation for clients with Parkinson's disease is tertiary prevention — it aims to maximize function and slow disability progression. Educating at-risk clients about diet is primary prevention (preventing disease onset). Screenings for early manifestations are secondary prevention (early detection). Education about diagnostic techniques does not fit prevention categories.
