Justfornowitwilldo, your relative is why I am going to be starting my nursing degree at age 46. I started my working life by working in one of the big Victorian psychiatric hospitals. You know, one of the ones they closed in the '80's. Most of the staff in them were as institutionalised as the patients.
I watched the programme about nurses a couple of years ago where a man was throwing faeces from his side room on to the ward a couple of years ago and the nurses shouted at him. She was clearly at a loss as to what to do with someone with obvious mental health problems of one kind or another.
I was torn between mental health and general nursing, as I love looking after the elderly with dementia. I currently work in a home for the elderly with mental health problems. I settled on Adult Nursing as the way things are going, there are increasing numbers of elderly with dementia on the general wards, so I will get to look after those I enjoy looking after and be doing that by choice rather than as an inconvenience to the 'real job' I want to do, which is how I feel some nurses by no mean all view it.
I cannot explain the situation you walked in to though and cannot guarantee I will never be in that situation. I cannot predict what management will force upon me. I can only promise I will do my best.
OP, as for nurse bashing, your op made me think of Amanda Holden (sorry) and the way she says she got a bashing on here. The reality is, she didn't. She had some people saying how terrible she was, she had a lot of people sticking up for her. That is what has happened about nurses this weekend. I was at one point disheartened, but I went back and re-read. There may be a minority slagging off nurses and, on the 'kettle chips' thread, there was certainly one repeatedly saying the same thing over and over but the majority were sticking up for nurses.
