We also don't know the level that this "nurse" is trained to... She could just be the lady that brings around the food trays and wheels the occupants to their spot in front of the TV.
It would be stretching it to call some of these workers "nurses". It sounds like the other location has actual nurses from what I read.
It's hard, but at that late age in life, sometimes it's time to go... I've seen old people die as it was their wish to just finally go and just let nature take its course, and I've been there when an elderly patient dies and everything possible is being done... Everyone goes eventually, and she knew that at that facility the attendants had to wait for the EMTs to arrive if she ever needed help.
If I lived in a place like the states, and was in that nurses shoes, I would have done what she did... People get sued way too easily, even if they had the best of intentions.
Even here in Ontario, my arse is covered and I would STILL be nervous about using some of the interventions that I'm trained in if I came up on an accident and someone was very seriously hurt... I would still do them, but that's because we're not in the US.
