I work in a SNF and we frequently have patients admitted with central lines and orders for IV ATBs. We use the IV infusion balls rather then pumps. Most of our patients will have double ports, a "purple" port for infusion and a "red" for blood draws. We currently have one patient who has orders for two seperate ATBs, one of the nurses apparently runs both ATBs at the same time, by connecting one to each of the two ports. The rest of us agree that this is not the correct procedure and that each ATB should be infused seperately and the red port should only be used for lab draws. What are some thoughts on this?
