Let's see: change bed linens, check. stock trauma bays, check. charge portable EKG batteries, check. take vital signs, check. draw blood for labs, check. mop up vomit, check. scribe during trauma, check. stock crash cart, check. transport patient to cath lab, check.
At least that's how it works here. You get lots of patient contact, but you're the nurse's little helper. You don't use any of your EMT skills (EMT-B is required to be an ER tech here). Some docs and nurses will teach you things as the day goes by, others just expect you to do all the things they don't want to.
If you need exposure and patient contact time, it's a good enough way to go.
