Have you ever used IVP into a primary line? When I was trained we only used saline lock to give IVP, and the IV line was always disconnected. We generally assumed incompatibility and did saline flush 5 ml medication flush 5 ml. I understand that we can give IVP into a primary line, but am concerned about compatibility of medications, and lack of time on a med surg floor. How do you handle IVP into a primary line with incompatible medications?Thank you in advance.
