I'm actually doing the opposite , I'm a former Corrections Officer going into nursing. I can't really speak to the nursing aspect of the job, but I worked for a large county jail in the NY/Metro area and if you want a challenging enviroment, you've found the right place. Our med dept was pretty much everything from a hospice to an ER, I've seen all types of trauma in there and you sort of become numb to it. From what I observed, the nurses spent most of the day loading meds onto the cart (They were interrupted often & understaffed) , dispensing meds to their assigned floors, dealing with inmates/patients that ask to go to sick call for a change of scenery, and the remainder of the time attending to whatever the Nurse Prac had going on. I've seen some Nurses last only a week and leave (One went to lunch and never returned), but the good ones start a little unsure of themselves (everyone is nervous when the first work in a jail) but you see them gain confidence over time as they start to own the job...It was pretty cool to watch them make the transition. You don't really need to be scared for your safety but always be aware of your enviroment. You'll never be "alone" with an inmate/patient without being "shawdowed" by a Corrections Officer and C/O's don't take kindly to inmates/patients that disrespect our nurses, most inmates/patients understand that from either 1st hand experience or word of mouth. Best of luck!
