I actually disagree with this because, in my experience, when you begin doing these things that are NOT your duty as a favor, it BECOMES your duty regardless of how busy you are. For example, teacher now decides, since the nurse is beginning to grade papers as a favor, she no longer grades them and your patient takes a turn for the worse and on that day, you are so busy with your patient, you don't get to grade the papers. The teacher may actually get upset because you didn't get to the papers losing sight of the actual reason why you are there. Another experience of mine is you are setting the standard for the nurses coming after you. You start doing teacher aide duties, then the nurse after you who refuses may get hostilities because "well, the nurse before you did it" etc. I'm more of a 'by the book' nurse and often conflict with nurses who do unethical or illegal things. An example is I had a patient come to me to give them medication to administer to a resident. The medication was to be given on the next shift. How am I to put my signature on such a medication without verifying it was given? I leave at 11, they "promised" to give it at 12 (an hour after I'm gone) but wanting me to sign for it anyway. When I explained the reason I needed to get a supervisor and the reason I couldn't just hand it over, the first thing the family member stated was "everyone else does it." Turns out everyone else was doing it wrong.
