My coworker hates IV's and never starts or restarts them if needed. She used to have another nurse on another unit come over and start them for her, but this other person is no longer available. Last night one of my pts had an IV due to dehydration. Upon making rounds I observed that the IV site was very edemetous. Turned off the IV and reported this to my coworker. She checked it out, but didn't restart it. Instead she flushed it with 125cc (?) of NS "To see what would happen" as she stated. Of course the arm became more edemetous, but she still didn't remove it or restart it. Shouldn't she have tried at least? Instead she left it for the next shift to deal with. Would this be considered a med error of some kind? Neglect? I'm thinking, "Gee, maybe you ought to hang yourself up on that IV pole........by your neck!" What's your opinion?
