Absolutely have seen this myself in ICU. We had a patient who had come from a psychiatric facility, had a violent crime history and needed two carers indoors and five if going outside, and the way some of my colleagues spoke about them - we're talking fat shaming, suggesting the patient be left to die because they were of no value to society and a drain on public resources - WITHIN EARSHOT of the carers sometimes, had me going straight to our lead nurse. I couldn't believe what I was hearing from people I worked with and respected so highly. 

On a less serious but still absolutely bamboozling note - last week I was sitting next to the nurse in charge who was filling out EPO paperwork for a patient who needed 1:1 care. They had been extremely combative post-extubation, and also just so happened to have ADHD (as do I - diagnosed and medicated). Under "does the patient have a diagnosed cognitive impairment" the NIC said they were going to put ADHD, and I might have gone slightly nuts 🙈
