I need advice from all of you seasoned CNA's.   I have a patient who is about 70yrs old and is morbidly obese and also has a rare bone disease that makes her bedridden.  This woman has a very nasty personality.  She has no respect for the staff.  She has cussed out everyone and is very verbally abusive to the staff that has the "privelege" to deal with her.  Because of her bone condition she has to use the bed pan from every twenty minutes to every hour on the hour.  Now here's my concern it's when doing her pericare.  She wants to be wiped a certain way.  And lets just say she seems to "get off" on it.  I just feel all yucky when I have to do this.  I also feel the pit of my stomach drop whenever I have to deal with her because of all the hostility she puts on people.  I've told my supervisors and they just say I have to deal with it.  I feel that I shouldn't have to be verbally abused by a patient that I am supposed to help.  It's one thing when a person is not in their right mind because of dementia or something like that then I can just brush it off but someone that is supposed to be aware of what they are doing and saying that's a whole different animal right there.  I just stress out having to think about dealing with her.  Any suggestions?
