As you can see, I never got any responses on this post. I did take the job and have been enjoying it immensely. It is not difficult in the way that floor nursing is, but it is busy in a much more "office-y" way. There are plenty of projects that I would like to get involved with but there are just not enough hours in the week. There are also opportunities to become involved with the workings of some multi-hospital initiatives on a broader/national level...but again, there are only so many hours in a week and your employer might not be willing to have you use your work time for that.
Lots of politics of course, as in any hospital job, but I see them from a different angle now.
As far as advancement opportunity, I think I do have more mobility if I wanted to make lateral job moves, for sure. I could also try to position myself to one day step into my bosses job when she is ready to leave. The job certainly has given me some opportunity to be known individually, rather than as one of many worker-bee floor nurses (that corporate folks rarely bother to interact with.)
I was offered my equivalent nursing salary to start, but negotiated a small increase for having an MSN degree.
If you would like to "talk shop" more specifically, feel free to shoot me a private message. It is such an interesting field and it would be fun to chat
