- 0Nov 18, '10 by biblepoetI am going to interview with the pulmonary unit in two weeks. I currently work as infirmary nurse at the prison. We generally get everyone who comes out of the hospital after surgery, cancer pts,etc basically med/surg like unit. What does the pulmonary unit do? How do I relate my experience to it? We have to suction there because no RT. Anything else that can help me with the interview would be great thanks in advance.
