One issue that comes to mind from working in nursing homes: Allowing residents to make choices that may not be the best for them healthwise.
For example( and I realize its not an exciting topic) I've seen some nursing staff basically order residents to eat more at meals, even though the residents apparently didn't want to. I knew of one Occupational Therapist who told the nursing assistents that certain residents couldn't leave the diningroom until they had drank all their liquids. At other nursing homes I've seen other nursing staff continually feed residents who had made it very clear they didn't want any more to eat or drink.
To be clear, I feel all these staff had the residents best interests at heart, and the residents I';m talking about had dementia to some degree However I think they should have respected the residents wishes more.
Personally, I would often try to get a resident to eat or drink more than they said they wanted. But if they made it clear that they didn't want anymore, then I would stop.
