This morning while I was trying to calculate I/O's, admin meds, cover fingersticks, etc...the end of shift duties, I asked my assistant if she had emptied the NG and colostomy and f/c in room 6. She said "nope". I asked her if she would do it. She said "nope, I wont." So I asked her why not. She said that the assistant-trainee needs to do it (this assistant is training her). Now normally I do this stuff myself because it always turned into a confrontation when I asked them to do anything. Well, this assistant-trainee doesnt know how to do it, she says she has never been shown how to. At this point, it was just easier to do it myself. But the rude assistant wouldnt leave it alone. She yelled at me in front of the entrie nurses station about how these new people need to do their job or find another one, that I need to go and show her how to do it! Umm, excuse me? It isnt my job to train the assistants. Im doing my job and its hard enough. Then she follows me to the medcart to argue with me some more. She gets mad and walks off yelling at me. Ya know, when she is swamped or busy, I always helped her do her blood draws, empty trash. I tried to work as a team. But apparently thats what is EXPECTED of me now. When I need help, there is no help to be found. Another nurse is the one who has to help me clean a patient who is a complete when they have a bm in the bed. The assistants on our floor will not clean a patient, will not empty f/c's, will not do any I/O's, they want to skip out on the vitals by asking "which patients do you have to have vitals on." I never ask an assistant to help me, because I get yelled at! The answer is "I dont have time." One day I had a shot in one hand and a cup of pills in the other and was going to a patient's room when another patient called out needing to go to the bathroom. Who do you think had to go...ME. I had to put the meds back in the medcart and go assist this patient to the bsc because the assistant didnt have time (she was standing at the nurses station talking). Ive gone to my nurse manager several times, as have many other nurses. It doesnt do any good. We are short staffed, which allows this behavior to continue. Im ready to QUIT but if I dont figure out how to handle this now, it will happen again at my next job. I dont know how to be assertive. This assistant has worked on this floor for 17years, Ive only worked there for 2 1/2 years. She literally thinks her role is more important than anyone elses. How would you handle an aggressive assistant like her?
