I work in PACU, and frequently have been pulling meds before or very shortly after a patient lands. Generally, I pull oxycodone, acetaminophen, dilaudid, fentanyl, and zofran for almost every patient. If it's ordered or I think I'm likely to need it, I'll also pull reglan, scopalomine, and / or toradol. I find that having these meds at the bedside makes it much easier to immediately respond to patient reports of pain or nausea, and it doesn't violate any policies. I know a lot of Endoscopy and procedure nurses pull up meds they expect to use during as case, but I wonder if anyone in recovery uses a similar method to streamline care.
edit, to address some of the comments: I have an order for the drugs, and I find that I use at least a portion (25 - 50 mcg fentanyl and 0.2 - 0.4 mg dilaudid in most patients) of the narcotics in 95% of the cases. We don't need a witness to return zofran, so that isn't an issue. Oxycodone and APAP are the typical discharge prescriptions, and we frequently start those right before the patients leave. The policies don't prohibit this; I've read them multiple times.
