Final answer:
The nurse should include the recommendation for the older adults to participate in regular cognitive activities to promote brain health. Physical exercise has cognitive benefits as well, but should be tailored to individual abilities and preferences.
Step-by-step explanation:
The nurse should include the recommendation for the older adults to participate in regular cognitive activities to promote brain health. Several studies have shown that engaging in cognitive activities can enhance cognitive function in older adults, helping to protect against neurodegenerative disorders such as dementia. Physical exercise has also been shown to have cognitive benefits, but high-impact aerobic exercises may not be suitable for all older adults. It is important to tailor the recommendations to the individuals' abilities and preferences.
