Was it a nursing home, or an assisted living center? They are two different things with different rules...
And had someone at this facility performed CPR, even if she had survived after, they would be fired for violating facility policy.
As I understand it the place where the woman was was basically a retirement home/community. It wasn't for assisted living or for persons needing medical attention.
On your second point, regardless of the person being fired for "violating policy" I think that'd make me, personally, feel better than to go the rest of my life wonder if I had done the nature of my job if it would have saved a life.
These women were nurses. I don't know if nurses take something akin to the Hippocratic Oath but these women are in a medical profession and are specifically trained to help save lives. To just stand there and do nothing while a woman suffocated to death or suffered from hear failure is utterly disgusting.
I would think "Stood idly by while an elderly woman died wondering on the phone 911 when help was going to arrive" looks worse on a resume than "attempted to save a life by providing CPR to someone who needed it, in spite of it being against policy."
Performing CPR wouldn't have put the woman -or the facility- in any legal trouble. (There are laws to prevent that. You can't get in trouble for failing to provide help.) However since this woman died since the professionals at this location refused to provide any level of life-saving care (including asking a passer-by to help -something even EMTs and firefighters are trained, and required, to do even when THEY are the ones arriving for help-) the facility is much more open to legal action from the family and possibly even criminal action from local law enforcement.
Anyone with a brain and a heart should hear this 911 call and be disgusted by the actions of the "nurses" at this facility. The woman is laying on the floor DYING, getting but a single breath once a minute or so and the nurses, people trained to provide life-saving care- are just standing there shrugging and saying they can't help.
I hope they all lose their licenses and are forced into another line of work. I also hope this retirement community has all of the residents flee it (either on their own or by their family members) and it gets shut down and turned into a parking lot.
