I have a dilemma I have been facing at work for sometime now. There is one nurse who gives out WAY more pain medication then any other nurse. It has always seemed weird to me but now alert and oriented patient are telling me they are not getting their pain medication when she is saying she is given them. Also this nurse will give more than what's prescribed if it's one every 8 hours PRN she will give one at 715 and 245 (shift is from 7-3). I have went to my DON multiple times about this and she said she did an investigation but nothing has happened no days off or anything. At the very least she making regular med errors (literally everyday she works) with giving them to frequently. But I know she is always taking them as well. I don't know what I should do. Should I go above my DON so something gets done about it? If so who do I report it to and is there anyway to do it anonymously?
