I'm reading all of these comments, well skimming them to be honest... what are you going to do with the patient? They're justified to be there by their need for medical treatment (I'm assuming or they wouldn't be there).... is everyone going to refuse to care for the patient? Because that's not an option. I've heard it many times before also "it's their right to abuse you". I've been in different situations when I heard it... being hit, kicked, bitten, etc. I know that some patients are a handful (too put it lightly), but I feel that some patients you have to find that way to great an awesome rapport with them, and know how to (sorry to say it this way) kiss their a** to make YOUR life better too. Some patients will ALWAYS be a pain in the a**... and that sucks, but seriously... we all signed up to take care of people... we didn't sign up to take care of the completely agreeable, pleasant, cooperative, AWESOME patients. Keep your chin up, I'm sure it's not personal :)
& if the patient is cognitive as you said... I'd never be afraid to put it out there plain & simple that you do NOT appreciate how she's acting/treating you, that you're trying your hardest to help her, and what is/is not acceptable.
