I would say, if you don't feel that what your being asked to do is within your role or your competency tell someone and don't do it.
Accidents happen when people don't speak up.
Advocate for patients. They are ill and their ability to navigate the system and challenge it is compromised.
Dignity. Being ill or needing hospital care impacts on people's dignity. Maintain it to the highest level possible.
Your therapeutic relationship is key and a priority. With trust people can relax and recover.
Try and keep people active, either by getting them up and about or by activity in bed. Pyjama paralysis is real.
Don't let anyone make you feel that HCAs are less important. You know the patient's, their families and what they are finding hard more than anyone. That information is vital.
I worked with a lady once who was blind. She was so rude and grumpy that the staff disliked her. She was plain nasty. Turned out she had a low level UTI for months and once the infection was cleared she was the most adorable lady ever. She had been so frightened and her cognition had been impaired by the infection. People are doing their best.
Kindness is free.
