1) Speed: Go in and say hi to your pt, QUICK focused assessment. Wait for the orders then go back in and do EVERYTHING. IV, meds, fluids...etc at the same time.
2) Delegating: Just speak up and when you know something is coming in tell the techs what you need. Our techs do a lot of blood draws (if im not starting an IV, or couldnt get labs), EKGs, urines, ambulating, meal ordering, paging for xray etc... When an ambulance is coming in i will say "We have a chest pain coming in, can you please grab the EKG machine, get vitals and hook the pt up to the monitor." Again, get EVERYTHING done in one trip to the room. Its a pain but i will often grab another nurse too if i know i have a very sick patient coming in and i need to get a line (or 2) in, labs done, an EKG, foley placed..etc..etc. If you are drowning tell your charge nurse, thats what they are there for.
3) This may be a facility issue - our codes (and yours) should be very organized. Someone on meds/tasks, someone on monitor, someone documenting. If we know a trauma/arrest is coming its important for someone to speak up and say "Who is doing what?" If my patient in a room codes i will scream "I NEED HELP IN HERE" and just start with the ABC's - just get chest compressions going ASAP. BLS first.
Good luck - it takes time but just lean on your other co-workers and be sure to be there for them when they are having a heavy pt load day too!
