"My parent"

My parent has been in hospital recently with cellulitis and I believe many nurses have treated them abhorrently. I understand they refuse to let my parent wash their hands when they go to the toilet; I believe they complain about helping to get them out of bed; at one point my parent moved their arm and the IV stopped working and they apologised to the nurse that came to fix it, at which the nurse said, I understand, you'd better be sorry; my parent needed their sheets changed and we called for a nurse, one brought sheets and said somebody else would come by later, only nobody showed up until 6 hours after I had left.

The nurses seem to intentionally cause pain to my parent, and pretend they don't know why they are crying out in pain. This is, in my opinion, unacceptably cruel treatment of a person with a serious infection and a great deal of pain, I worry their apparent negligence is going to cause my parent further harm.
