Final answer:
The nurse should recommend that older adults engage in regular cognitive and physical exercises, maintain social interactions, and follow a healthy diet low in saturated fats to promote overall well-being and reduce the risk of chronic diseases.
Step-by-step explanation:
Among the recommendations a nurse should include in an educational program for older adults, the option to engage in cognitive exercises regularly is the most beneficial. This advice is aligned with the evidence that physical exercise, particularly aerobic activity, can enhance cognitive function, reduce the risk of neurodegenerative disorders, and can potentially help reverse certain types of brain damage. The Department of Health and Human Services recommends that adults engage in regular aerobic physical activity to improve overall health. It is also found that social interaction is beneficial for mental health and that maintaining a healthy diet, especially one low in saturated fats, is essential for reducing the risk of chronic diseases. Therefore, avoiding regular physical activity, limiting social interactions, and maintaining a diet high in saturated fats are not advisable for promoting health in older adults.
