AnthonyD 228 Posts Specializes in Critical Care, Med-Surg. Has 7 years experience. May 15, 2008 Working as a PCT in the emergency dept. I had a nurse hand me a blood gas to take to the lab, just in a bag. I said, "It needs to be on ice first," to which she responded. "No, that is a room air blood gas, which means it doesn't go on ice." :uhoh21:I just stared at her, not sure what to say... she then reiterated that it was a room air blood gas and didn't need to be iced, I told her I was verifying that with the Doc first... He promptly corrected her. ---Same nurse, different day... calls me over and hands me a requisition to get 2 units PRBC's from the blood bank and says, "Now make sure you get the red blood, not the other kind."
