As I have been doing my job searching, I am seeing more and more that graduate nurses MUST go through some type of internship or residency before going on the floor. Hospitals want to safeguard themselves by doing this and I think it's an awesome idea. Some are 12-18 weeks some less and some more. I am currently looking to get into a residency program and then have a preceptor on the floor. I have heard horror stories from past times when nurses right out of the BSN program are put in charge positions 2-3 months or less after graduating! I don't think that is right. So if I were you, just to build confidence and get as familiar as possible with the environment in which you will be working, I would definitely go for the internship and residency especially since it's pretty much required in most acute care settings. Happy hunting!
