We do this in my ED, either in triage or after the nurse is assigned the patient from triage we can order all this stuff. There are standing orders for all labwork, x-rays, and EKG's, as well as the other things like the heplock, monitor, oxygen, nebulizer treatments, aspirin for chest pains, and tylenol/motrin for fevers. It seems to be working out well for both us (the nurses) and the doctors. I can get everything done without having to wait for the doc to order it, and you can have your results and stuff ready for when you pick up the patient.
