I love having students, I plan my day around making it the best clinical experience for them that I can. I try to treat them like they are the nurse, Ill snag an extra vocera and log them in as one of the night shift people and tell the monitor tech to call them for their patients. This last clinical group we had would fight to be placed with me. But there are always the few who don't seem to want to take advantage of the opportunities that clinicals present to them.
Personally, the thing that bothers me the most about "lazy" students is that they don't seem to understand that I end up having a ton of extra work, and will end up staying after 15-30mins to finish everything because I've spent the day trying to make sure that they had the opportunities available to them, and that they had ample time to learn and not feel rushed. I don't need a cookie for that, but Id like a little effort since it is the profession they chose to pursue.
