I think it is something you should try, although it isn't for everyone. I would suggest walking into a facility you are considering around 6 pm when the chiefs have gone home and the Indians are fending for themselves, just to see if they seem ok-not frazzled and generally friendly.
There is a common misconception in my area that "nursing home nurses" do not use the same skills as a "hospital nurse" would, I can assure you this is not the case. My night is spent passing meds, assessing pts. supervising staff, dealing with families, phone calls, etc.
I say give it a go!
