I can say I have nothing but love for the older male nurses (I mean over 30) that I work with. That said, the younger ones have got to be the most apathetic, jerky people I have ever had to deal with. They specifically work at night because they don't want to really deal with patients when they're actually awake. They specifically wear the light blue "MD-looking" scrubs so that they will be treated like doctors, and many times are--because they're men, and they've purposely dressed this way. The more mature men on my floor don't care what color scrubs they wear, and seem very helpful and kind and caring. Time and time again I witness a patient who is reluctant to ask anything "petty" of these guys (like fetching a glass of water or a snack, etc) but will think nothing of calling some random female nurse to come do it.
It' a disservice to any male nurse that really cares about his practice and isn't just "slumming it" because he couldn't get into med school. Nursing is not "slumming it" and if you have to pick a night shift to do your job because the thought of dealing with people when they're conscious is so irritating, rethink what you're doing and go into research.
