Couple of tips...
Does meditech have something like 'acronym expansion'? I use SCM and will use the acronym $discharged that the system writes out as "Patient AOx4, respirations even and unlabored. Patient states pain level tolerable to leave facility at this time" and use that on my discharge note. Little things like this save only seconds, but over 12 hours it adds up!
When I first started, it was hard for me to get a patient history unless I was standing still and looking the patient right in the eyes. BIG time sucker. Now I get history while hooking them up to the monitor. If they are vomiting I get history while starting the IV. You get the idea. Before I leave the room I make sure to chart and then I might say "I just want to clarify, you said your symptoms started yesterday?" or something to that nature.
When you are new and have a preceptor, other nurses usually won't help you out for two reasons. One, you already have two nurses to cover one patient load, so you technically already have "help". Two, when you are new is the time to struggle, figure out your rhythm, figure out your resources. You can't start out relying on other people's help. All of this does not include Level 2 ESI or higher. If your co-workers are not helping you during acute strokes or full arrests there is something wrong.
It gets better but these are the rough times!
