Wow Ruby Vee, I am disappointed in your comment. It actually is scary you wouldn't precept someone as well as someone else just because you think they are on a "two year plan". Maybe so many RNs leave after two years because they are purposely given ****** patients. Maybe you need to talk to management about the amount of new RNs that are hired on your floor.
Just because someone has different career goals than you doesn't mean they think the ICU is beneath them or they are meant for more. It means they have chosen to pursue anesthesia and need to work in an ICU setting, something they actually may really enjoy and want to learn as much as they can about until they have to precepted by you. Why don't you keep an open mind and give that idea a chance?
In regards to the question, hopefully you work on a unit you are comfortable with your coworkers and manager and can talk to them about it because it's a big decision and time in your life. If not then don't tell anyone and when it's time to move on, move on.
