After *cough* years in emergency nursing and medicine...I'm not only considering it, but I'm applying for a position at the local jail. And prison.
Why? Because the attitudes that I started out with in regards to interacting with patients have changed. No longer can we truly give tough love to the people who need it; we have to wrap everybody in silk and bubble wrap to provide not patient - centered care, but customer service to everybody, up to and including our co-workers. There are some days that I'm not a nurse, I'm a waitress, housekeeper, and servant.
Is it dangerous? No more than working in an inner-city ER. Less, actually. The patients, for the most part, know that they need to be at the very least polite to the medical/nursing staff. They're in restraints of some form, and there are guards present. There also isn't much call for the nurses to leave the infirmary and go out into the cell blocks.
The one thing that has to be remembered is that for all the men and women, and children who end up incarcerated, they are there for a reason. They were given fair trials, found guilty, and given a punishment to fit the crime according to the laws of the nation that you live in and either a jury of their peers or a judge who is trained in trial law and sentencing. It's not my place, nor in my capabilities, to feel bad or sorry for them.
