A nurse is teaching a client about the purpose of flushing their IV site before and after medication administration. Which of the following information should the nurse include in the teaching?

Nursing care related to IV medication administration includes ensuring patency, preventing complications, and promoting safe delivery of prescribed therapies. Flushing an IV site before and after medication administration is a standard practice used to assess catheter function and maintain line patency. This step helps confirm that the intravenous access device is correctly positioned within the vein and free from obstruction. It also ensures that medications are delivered effectively without complications such as infiltration or occlusion. Rationale: A. Ensuring the IV line is clear of air before administration is not the primary purpose of flushing. Air prevention is managed by properly priming IV tubing and medication syringes before administration. Flushing mainly assesses patency and ensures the catheter is functioning rather than removing air from the system. B. Maintaining sterile technique is important during IV care, but flushing itself does not establish or maintain sterility. Aseptic technique is used during insertion and access of the IV line, while flushing is a mechanical process to assess and maintain patency. Therefore, sterility is not the primary purpose of this action. C. Verifying the IV line is working properly is the correct purpose of flushing because it confirms patency before and after medication administration. A patent IV line allows for proper delivery of medication into the bloodstream without leakage or resistance. It also helps identify complications such as infiltration, phlebitis, or occlusion early. D. Minimizing the risk for medication errors is not the primary purpose of flushing, although it indirectly supports safe administration. Medication errors are primarily prevented through the rights of medication administration and proper verification processes. Flushing is focused on ensuring the IV access device is functional rather than preventing dosage or identification errors.
