A nurse and doctor have personal liability in the US.
Imagine having to do paperwork as a nurse after working a 12 hour physical job, overnight, 8pm to 8am.
The idea mistakes happen because the nurse doesn't "care" is utter bullshit.
I think of how if I am really tired I just don't do anything that risky at my job until the next day. A nurse doesn't really have that option and it is all the highest risk there is. Every day, all day. All with a chronic, massive work shortage for dogshit pay.
The most brutal thing I have read about nursing are nurses saying the lucky people are the ones who failed out of nursing school.
