The nurse that precepted me on my first job out of Nursing school
was one mean motorscooter of a nurse. She would very mean to the dementia patients - talking about throwing them out the window if they didn't quiet down. One day, she was evil to an oriented but sedated elderly lady - found out later that she was related to a senator - the nurse disappeared from staffing - needed to take some unexpected time off. Did she fall or was she pushed (fired or quit), I don't know.
On the lighter side, she used to place me on the "Dirty" side (infectious disease) and she would take the "Clean" side because it was easier (less meds, fewer IVs, fewer diabetics, no VRE/MRSA, no isolations, no HIV/TB). I learned a great deal, learned isolation technique, good time management skills, how to deal difficult co-workers, and learned to love HIV patients and the art of dealing w/infectious disease. I went through heck and learned that I could handle it.
I did do a dance of sheer joy though when the witch was gone!!!
