Preferably an LPN, not an rn. Then get a recommendation from her (assuming her, such as my wife). That is the only way you have a chance of a good placement. Hang out at the possible nursing home of choice, be there for a late shift change, and talk to the smokers. Then follow them to the bar (the vast majority of them need a wind down drink or two or twenty). Tough job. Then hang for a bit, buy them a few drinks, and then pump them for info. They will tell you the horror places and the ones that are better.

My wife's patients all die sooner or later. And they love her. It is her job to see them through to the other side.
