Going to work always makes me anxious. You know, when you can't sleep, eat, or enjoy life. When your brain is consumed by what will happen and how you will handle it all.Granted, some days go well, and it actually feels like I enjoy my job; there are far too many days like a few days ago. Maybe this is nothing and I just need to find a new line of work, or maybe it is just nursing. I work ortho. Started the evening with 4 patients; gave 3 to the LPN on my team in anticipation of landing 3 surgical. Easy start, no doubt.Turns out, all 3 patients returned from PACU within one hour; the last 2 within 5 minutes of each other. The floor was getting other surgicals as well, and I was the only core RN on the floor, so the help on the floor was minimal. Paged the nursing supervisor to ask for some help. That page was not answered until 2 hours later; im quite sure the HUC made repeated attempts. Not throwing the sup under the bus; I know the entire hospital was chaos.One PACU nurse reported that one of the patients came out of anesthesia quite lethargic and received 20 of morphine, but his resps were 12-16 and he was improving. Needless to say, when the patient got to the floor, his resps were 8-10, and was barely responsive.Long story short, he got narcan twice and had rapid response called when his sats hit the 60s after receiving narcan once, while on 6 liters. I can manage this patient, but not with 2 other fresh surgicals, plus another fresh surgical from day shift and 3 other patients in my team to be responsible for.I am not throwing my coworkers under the bus, but honestly I called for help in all the right places and got almost nothing. The level of responsibility I had was too much. It was a very vulnerable situation and my team and I were left out to dry; but ultimately everything was on my shoulders.I guess this is nursing, and I guess we all have days like this. My question is, how the heck does being placed in these situations allow anyone to enjoy work? Avoid anxiety? I am in the process of dealing with all of these issues in terms of reporting and filing unsafe staffing. I just feel like this is a bad deal, and am curious to know if I am over reacting or if this is just nursing as we know it.
