KwowRn

Working night shift, the only nurses in the building are myself (the RN) and my co-worker (the LPN). The LPN makes it known to me through her actions that she really despises me. She gets mad at me and yells at me for doing my job. For example, I am in charge of a psychotropic audit. When I told her that she forgot to fill out the column from the night before and to make sure it got done, she flipped out at me and yelled, saying I am overstepping my boundaries and that the RN that had my job before me was a much better nurse because she would let it slide. Then, tonight she asked me to sign that I witnessed the wasting of a narcotic. I signed, and followed her to the cart. She told me I could take my break. I told her that I would take my break after I witnessed the wasting of the narcotic. She then got angry and defensive, saying "I didn't realize I wasn't trustworthy." I explained to her that I have nothing against her, and that it's the law to actually witness the wasting, not just say that I did and walk away. She didn't want to hear any of it. She has ignored me the rest of the night. It is just so frustrating to be yelled at and hated for simply doing my job. I feel as though I can't vent to other staff members about this because they are all friends with the LPN. Is there any advice on how to handle a co-worker who exhibits this behavior?
