Second, I wonder if she'll be liable for a civil suit by the family, if she did have a duty to act.
In todays paper, an article said the family stated she was in that facility because she wanted to die with dignity, without all the "medical care".
That is fine if that is their wish. However, they could have avoided a lot of controversy for a lot of people if they had also made the effort to get a formal DNR ("Do Not Resuscitate") order. In most jurisdictions, Dispatchers, EMTs and Paramedics are obligated to try to resuscitate if they don't see a formal, legal, hardcopy DNR.
