May I ask if you go to a chain clinic such as DaVita or FMC or do you use a private company for your dialysis? Sir, if you receive dialysis at a chain company, I urge you to contact your clinics regional director and if that does not hel you, IMMEDIATLY go to his supervisor, the regional VP. If you are at a clinic that is not a chain, I urge you sir to contact your renal network and file a complaint. This "nurse" (and I use that term lightly) should not be allowed to practice. The renal network will help you if you need it. As a former CD/FA I can assure you that you have rights and one of them is to not be abused by staff. Please let us know how things are going. Good luck.
