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?

Choice A reason: Preventing leakage is not the primary purpose of flushing an intermittent infusion device. Flushing maintains patency by clearing blood or medication residue, preventing clots or blockages. Leakage is addressed by proper capping or clamping, not flushing, making this statement incorrect as it misrepresents the procedure’s purpose. Choice B reason: Flushing an infusion device does not contribute to hydration, as the flush solution (typically saline) is minimal and not intended for fluid replacement. The purpose is to maintain catheter patency by clearing debris or clots. This statement is incorrect, as it inaccurately suggests a hydration benefit unrelated to the procedure. Choice C reason: Flushing an intermittent infusion device with saline clears blood or medication residue from the catheter, preventing occlusion and maintaining patency. Blood left in the line can clot, increasing infection risk or blocking the device. This statement accurately reflects the procedure’s purpose, ensuring continued functionality for future medication administration. Choice D reason: Flushing does not ensure sterility, as the device is already in place and exposed to the bloodstream. Sterility is maintained during insertion or access, not flushing. The primary goal is patency, not sterilization, making this statement incorrect as it misaligns with the procedure’s clinical purpose.
