A nurse is flushing a client's intermittent infusion device. The client states, "Why do you have to do that if you are not giving me medicine?" Which of the following statements should the nurse make?

Rationale: A. "This helps to keep you hydrated.": Flushing an intermittent infusion device does not hydrate the client, as the small amount of saline used is not intended for fluid replacement. Hydration is achieved through continuous or scheduled fluid administration, not flushes. B. "This clears blood from the tubing and the catheter.": Flushing helps maintain catheter patency by preventing blood from clotting inside the lumen. It ensures the device remains functional and ready for medication administration when needed. C. "This makes sure it stays sterile.": Flushing does not sterilize the device. Sterility is maintained through proper handling and use of aseptic technique. The purpose of flushing is mechanical, not antimicrobial. D. "This prevents leakage of fluid and medication.": While flushing may help confirm that the device is intact, the primary reason is not to prevent leakage but to maintain patency and ensure the catheter is free of occlusions.
