***I am a student nurse, so this is coming from MY perspective given all of the feedback going on in previous comments.***
Here is the tl;dr version of how I think things should be:
-Students should be responsible for completing tasks that they are allowed to, and should be responsible for knowing what they can and cannot complete on the floor during clinicals.
-I believe that instructors should do the bulk of the teaching, but there are some things that can only be "shown" and so I think that is where nurses come in to their "teaching" role, if you would even call it that. However, students should be responsible for stepping up to the plate and asking to watch, not waiting around for a nurse to usher them in.
-As a professional, you should conduct yourself with an appropriate attitude when students are present. We know we're in the way, we don't need your eye rolls, your condescending comments, or your huffs. Think about it- you were once us. How would it make you feel? Even more in the way, unappreciated, dumb? Yeah.
-The laissez-faire attitude that you simply don't give a damn about student nurses is why this profession is deemed catty (well, that and the patriarchy, but that's for another time). Please give us the time of day (when you have the chance)- most of us really appreciate it.
-I understand that it may not be your choice to be my "parent" for the day, but it is not our problem. It is the administration's problem, or the school's problem. Please don't take it out on us.
(Alright, let's see how much hate I'll get.)
