Not sure if this applies to your facility, but at my facility many of the ICU type cardiac/sedation drips aren't accepted in PCU-must be weaned off the IV stuff before they can ship out of ICU.
But as the above person suggested, being familiar with cardiac meds is a good idea. I'd like to add anti seizure meds (Phenytoin, Keppra, etc) to that list as well. Many patients are still getting IV antibiotics as well- wouldn't be a bad idea to familiarize yourself with those too and know side effects/toxicities associated with them (Vanco, Zosyn, Unasyn)
Also, know your blood products and protocol at your facility for hanging each of them! FFP, cryo, PRBCs, platelets. It was slightly embarrassing coming to my current facility having never hung a single blood product and not knowing the protocol for each of them. (My last job had a blood team that would hang our blood products/do the monitoring for us).
