First of all, and I have to say this... Med/Surg is more than a foundation. It is a specialty field. I wish more people would recognize this.
With that being said, your ED is passing along garbage care. Are they that busy, that they can't do the NG's etc..prior to coming up to the floor? Do you have a way of seeing the ED orders prior to the pt coming to the floor? Can you write them up for missed orders? Do you have backing from your management team? Something is really wrong with your ED to Med/Surg flow. Until that is fixed, you are going to have really bad shifts.
Where I work, we had a redesign of the ED to Med/Surg flow. Our motto: No passing garbage. If a pt is soiled, abnormal vitals, needing tubes, etc.. it's supposed to be started or fixed in ED. If not, then we have the right to say No to the pt coming to the floor. If a nurse brings the pt up anyway, it gets reported to their manager.
On top of your high pt load, no wonder you have such crap shifts.
You and your team need to speak up or you will be miserable until you either leave or it's fixed.
BTW, Med/Surg doesn't have to be an awful place to work.
