I've held a position such as you've described, and as much as I hate to say this, it was the hardest work I've ever done.
For two years I was an admissions nurse working 11 AM-7PM, and the more I did, the more management and my co-workers expected, until I was handling as many as 10 admissions, sometimes on two or even three different units, per 8-hour shift. Sometimes I had to admit several patients simultaneously. I was constantly being pushed, pushed, pushed to get the admissions done so I could hand them off to the floor nurses and do the next one, but then I'd end up having to KEEP them! I'd get the paperwork done, start the IV, put in the Foley, initiate AND process the admit orders, and in the middle of all this I'd get another admission while I was doing all the care for my
other four or five admits.
If I'd known then what I know now, I'd never have taken that position........sure hope your experience is better than mine.
