1: It sounds asisine because you did not do it as a student. People tend to be against anything they are inexperienced with. Also being a charge is part of a nurse's scope, so why not get exposure to that role during nursing school and learn what it entails? Nurses are becoming charge nurses within a year of being in practice. As the charge, we were to get report on ALL of those patients under the care of that student, cover lunch breaks, help with med passes, morning care, and to be an extra hand to our fellow students.
If they were falling behind, we would be of an assistance to get them back up to speed. If the students had any issues they would come to us and we would work through it (you know... problem solve) before we go to the instructor/nurs. It's all about time management.
All of my clinical groups had 7 students and during our final preceptorship, we had 5 students for 1 instructor...but we were assigned to 1 nurse and all of their patients during that 12 hour shift.
2: If they had doubts they would approach their fellow student themself and inquire if they had any issues getting the blood pressure (example of double checking each other). A licensed nurse would go straight to the source and not to ANOTHER NURSE to gossip (example of not double checking each other). That's how lateral bullying occurs and the forming of cliques. If she was advocating for the patient, she would retake the blood pressure herself and compare results (to note any large discrepancy). Let's not fool ourselves, the title "charge" went to their head and they took this role way too serious.
You state if you're doing your job well then they shouldn't be offended? Yet, everyday on this forum there is a seasoned nurse who is doing their job well complaining of upper management micromanaging them. Frustration is part of the job, but my take is to let things roll of your sleeves if they're not "cutting you a check"
