I am in my last quarter of an ADN program and I have a question that I'm too embarrassed to ask my instructors....something I should probably know by now. If you have a piggyback that is not compatible with the primary infusion, can you clamp the primary line above the y-port, flush it, give the piggyback, flush again, and resume primary infusion. I only ask because I looked back on some old notes from my first quarter and saw this written. Never seen it done and seems like it'd be a pain in the butt.
