Awkward!!

I was intermittent charge the other night. While in a pts room with the nurse I noticed her about to perform an action that would compromise the pt. wouldn't be a sentinel event but still it shouldn't have been done. I calmly told her you can't do that. She asked why and I gave her the reason. She got really upset and stormed out of the room leaving me to care for the pt (on a vent).

After it was done I pulled her aside to attempt to tell her why I stopped her and what would have resulted from her actions she gave a snarky remark and refused to speak to me for the rest of the shift.

I refuse to apologize to her as I feal I did nothing wrong here. I am not planning on going to management as I feal you can't manage poor attitudes, it just makes it worse.

The rest of that shift was so awkward especially since we were working from the same nursing station. So my question is this. How do you deal with this type of situation and keep a positive attitude throughout the shift?
