Final answer:
To help aging parents, consult healthcare professionals and explore community and in-home care services. Avoid unqualified advice.
Step-by-step explanation:
Appropriate resources for a friend concerned about their elderly parents' changing health needs would include seeking advice from healthcare professionals, looking into community support services, and considering in-home care options. An inappropriate resource might be relying on someone with no medical background or experience in elder care for guidance. It's important to assess the parents' needs carefully and explore all available resources, which may include consulting with geriatric specialists, researching local elder care services, and reviewing financial options for professional healthcare. Providing support to the friend by discussing comprehensive healthcare planning and disease prevention for her elderly parents is essential.
