You'll do fine. Your nurse isn't going to expect you to know everything when you first walk through the door. I work in an ER now, and trust me, I didn't know much when I started (after nursing school
and the dreaded boards mind you). Just look up some of the more common drugs and print out a little sheet that you can keep in your pocket, if that makes ya feel better... I can list some of the ones we use commonly in my pediatric ER, but I'm not down with the adult meds. Also, on finding pulses, it comes with time as well, knowing exactly where to feel. Look in your textbooks and they'll have good diagrams on where to find pulses. Finally, don't be afraid to ask questions! There's no such thing as a stupid question and your preceptor will be willing to show you how to do things, no biggie! With foot pulses, if the foot is pink and good cap refill, chances are there's a pulse, so that's a good bet too if you're really struggling... you'll figure it out, just takes time.
List of common drugs in my ER (remember, I just work peds).
And the most common of all:
Tylenol and Advil.... use them ALL the time, most common drug by far
I kind of divided them up into pseudo groups like antibiotics, pain meds, code drugs (if we're gonna intubate), Sedation medications (for fx reductions and such), and then asthma meds.
Once again, this is just a brief list. Don't think you need to know all of them, just what group they're in and major side effects. You'll do fine and remember, you don't have to know it all! You're still a student and there to learn!
