I'm happy to start.
I would say that the standards are the same, and the expectation for nurses, regardless of what setting they're working in, is the same.
I think some of the challenges in the facilities you're talking about relate to a blurring of roles and an understanding within the setting of the role of a nurse as opposed to the role of a correctional officer. There are times when nurses are put in positions where their ability to practise according to the standards of the profession is not well understood and may be compromised because of the way settings are staffed and the policies and requirements in those facilities.
