Funny, I replied to that post a while back, and still think it is a good way to explain it.
As for standing orders/protocols, it will depend on your facility. Mine does not, and it is annoying.
1:5-6 is a lot. 1:4 is becoming the norm for many, but not all.
A big part depends on the acuity. Some fast track areas have 1 nurse, 1 mid-level and maybe
a tech with 20+ patients.
There are times when you are stuck 1:1, and unfortunately your other patients suffer if you do not have good support.
You know your learning style, so that puts you ahead in that part, but talk to your educator (if you have one) and your preceptor. Most preceptors are in that position because they want to be (but not all). They want you to be successful because they will be working with you when you are off orientation, and want you to be competent.
Getting faster takes time. There is no shortcut. You will feel like you are slowing things down, that others are griping behind your back, and it is true. But it is expected. Now if after a year you are still as slow, that is a different story. It is beyond frustrating when your busting you rear and moving patients and you see "that nurse" that has had the same 4 patients for the last 5 hours and it seems nothing has been done for them (meds ordered for 3 hours, assessment not charted, screening not done, ready for discharge for a hour, etc). But if you are still new to the ER, you should get some slack from most.
