I am a CNA inside of a small hospital. Couple of days ago I took vitals. I missed a crucial part with not reporting low 02 to the nurse because I couldn't find her and ultimately forgot. I did chart ontime, but I forgot. I understand that was bad. I am always good with reporting what is questionable. The nurse came to me a couple of hours later upset that I didn't report. I explained I forgot. My question is why don't the nurses check the vitals on the computers? I know for the most part I am documenting every two hours. So how often are nurses checking and documenting. Don't come to me and put the blame on me when I feel it's a simple lookup right after vitals are taking just because of common mistakes like this. Me forgetting. So I just need some input. I know from now on I will be bringing all vitals to nurses before putting them in the computer whether they catch an attitude or not. I have to chase nurses down all the time because they hide or just give you a nasty attitude because you're bothering them when reporting abnormal VS.
