I will agree with MistyDawn that ICU nurses can be vultures. I went straight into ICU after nursing school (which I now think was a mistake FOR ME--maybe not for others, not judging). It has been rough. I quit the first job after 4 months due to many factors (manager promised day/pm rotation, and then put me on 4 nights a week--go figure! Had 15 preceptors, most of who were just obsessed that the chart had every box checked, as opposed to worrying abou the patient) Now I am in another ICU, and supposedly some of my coworkers are critical of my care (one said my patients looked "rumpled"). Manager could not give me specific examples, however. Never made a med error, patients are happy, etc.
So, I applied for a transfer to a med-surg floor, and all of a sudden, my ICU manager thinks I am just fine. She wants to talk now and have me reconsider, etc. etc.
I think the point is that some ICUs have nurses who are horribly picky, and until you have 10 years of ICU experience and dot every i on the chart, you will not be respected.
I would definitely say to other ICUs you are interviewing with, as previous poster did, that the orientation was not sufficient, and you are looking for a better fit, or something like that.
