I am going to be interviewing in the PCU (float to the ICU) this coming week. I've seen how the CNA's work in the surgical floor of the hospital, but what do they usually do in the PCU? Do they normally take vitals or is this usually done by tele or the RN's? I understand what a PCU is, but what is the difference in work load? Is PCU still considered critical care? Thanks for your help!
