Thanks for replying. SteveRN21 you are correct. I found out the dept was Peds Cardiac Interventional Unit.
EricEnfermero - thanks for posting too. At first I thought that I misheard them and that they were talking about PCU but nope it was PCIU! I work for a staffing agency and had a nurse going to the PCIU unit and had no clue what that was, so I was curious. The nursing super that I had talked to initally didn't know either, now that is scary that they didn't know what the unit stood for, all they knew is that they needed staff there.
