Six weeks is just not enough time to properly orient a new grad. It IS enough time to orient a new employee that's already an experienced nurse. They're setting you up for failure and they may or may not know that.
How do you "get it all done" when you have that much "stuff" to do? You prioritize. What absolutely needs to be done? What can you get done fast? Who is the most sick patient? Who can you ask to help you out?
How do I get things done when I've got that kind of a load? I delegate tasks. I get the UA to help me get the patient undressed and the EKG done while I hook the patient up to the monitor. I listen to the report from EMS and ask questions while the patient is getting into the gown, hooked up to the monitor, and getting that EKG done. If I know an RN has a free moment, I'll ask them to medicate or discharge a patient of mine. That's a task off my plate. For that impossible to stick vomiting patient, I'll ask the charge nurse to find someone that can do an ultrasound IV to try to place a line or I'll ask a provider to do it because they can't get a peripheral line, they'll know right away if they need to put in a central line. That's now a task off my plate. If lab needs another draw, then they'll have to come get it themselves. I don't have time to draw a purple top for them, get it labeled, and sent it to them... That's yet another task off my plate. As to charting, I try to chart something on my patients whenever I pass by a computer that's "mine" or every time I'm in the room and the computer in the room is actually working. The charting doesn't often have to be much but it should reflect what you see or have discussed at the time, or what your patient is doing or where they've gone and why.
With time you'll get faster and faster. The problem is that as a new grad, and having such a short orientation, you just are going to be slow.
My last shift was in a fast track area. I probably saw a dozen patients during the course of my shift, 4 or 5 of them just were in my area for various procedures like laceration repairs, pelvic exams, or the like. That day I probably had an hour of time sitting in a chair and that included lunch... no other breaks because we were just too busy. With all that, I still had time to help out some of my peers, consult with the providers, take samples to the lab, and so on. I'm not that fast but compared to how I was when I first graduated, I'm Speedy Gonzales! I've only been in the ED for 3 years but I still enjoy it and other nurses sometimes come to me for advice on how to do things.
How do you get fast at things? Go slow... Remember the old adage: "Slow is smooth. Smooth is fast. Slow is fast." By doing certain tasks slowly, you'll do them smoothly and get it done right the first time. For an uncomplicated IV start, it only takes me about 3 minutes to get it done from start to finish. It's all because I first choose the site, do the chloraprep, prime the extension set while the chloraprep is drying, tear tape, get my tegaderm ready, etc... all before the chloraprep is dry. It's just a series of simple tasks done quickly. Then I do the venipuncture and put it all together fast because it has already been preset. Slow, smooth, deliberate efficient movement = fast.
I just hope that when you're done with your orientation that you won't be thrown into the deep end of the pool. There are more than a few nurses that work in the ED that believe that the ED is no place for a new grad to start. It is very possible if the orientation period accounts for the additional teaching and support that a new grad needs to not only learn to be a nurse, but to also learn to be an ED nurse. I was lucky. My orientation was 16 weeks. I have since changed employers and my "new" job orientation was just 6 weeks, but for various reasons, was really effectively about 4. By then I was already experienced as an ED nurse so most of what I needed was to know where things were and who to talk to. I'm still learning and I expect to keep learning for quite a while to come!
Best of luck to you, I hope you succeed, and welcome to the 3 ring circus known as the Emergency Department!
