I am newly hired staff nurse in a nursing home. I have been working by myself for the past 2 weeks now. I need your advice fellow nurses regarding the situation. One of our resident who has generalized weakness had his tooth pulled at 5pm. When I arrived for my morning shift the next day, I got the report regarding no swishing, no spitting, and no use of straw. At around 8am I gave him his meds, and he took it, but the problem was, the wife noticed that there was something different in her husband's appearance. She found a gauze left from yesterday and she was really upset about it. I know the wife will report the incident to our manager. Now, I know that I should've check the inside of his mouth but because I read the last 2 shifts notes, it stated there that there were no bleeding. I would've not thought about a gauze being left there overnight because he could've swallowed it. It was not stated in the note and I did not get a report regarding the gauze being left overnight from the outgoing shift. How can I cover myself and not get in trouble with this. Please help!
