Just thought I'd update the situation:
Heard from the noc nurse that mom thinks one of us (the three nurses on her case) stole - wait for it guys! - trach ties from her. And that some of her DVDs are missing.
Her DVDs are missing because she doesn't put them back in the case but dumps the disks into a big box. But stealing trach ties? C'mon.
Noc nurse says she throws out accusations like this every few months. I called the agency to go on the record stating that I did not steal trach ties or DVDs -- but the agency said that she hadn't called to say anything about stealing, so.
I'm on the fence about asking to move off this case. I think it could get very crazy very fast with this mom -- and I know I lack the experience and backbone to handle any sort of confrontation.
