You have noticed correctly! It's a tough enough job without colleagues pouncing on you for any little oversight or infraction. I worked the night shift and in one case I failed to remove a pt's heparin lock as ordered by a MD. The day shift nurse also failed to notice that the heparin lock was not removed. The blame landed squarely on my shoulders. I accepted it--I realized I wasn't perfect. But for crying out loud! Once the problem was identified couldn't it have easily gotten taken care of without attacks? You have heard of the phrase "Nurses eat their young"? I have found this to be soo true. Mainly I believe that older nurses can be threatened and annoyed by the youthful vibrancy, excitement, and knowledge base of new nurses. I've definitely encountered theses attacks many times, but on the other hand I've also encountered great mentors and kindhearted nurses also.
