Baths? I/Os? TF you talking about? Everybody knows ER nurses don't do that kind of stuff. ?
In all seriousness though, it's gotta be a REALLY slow day if I'm giving someone a bath. Not because I don't want to, which I don't, but because baths don't help the practitioner make their diagnosis, don't determine the course of care, and won't affect disposition... and are therefore prioritized lower than anything else that does one of those things. You may wind up doing one, but only if the outcome of that bath helps determine whether they are discharged, admitted, and to which service. Otherwise, turn over the room and grab the next one.
In 14 years, I've given maybe 2 bed baths [on boarders, naturally]... I doubt you'll be giving them a much as you may envision.
