Which action is a best practice the nurse can employ to prevent catheter-related bloodstream infections?

Flushing intravenous (IV) lines with saline regularly is considered a best practice for preventing catheter-related bloodstream infections (CRBSIs). This action helps maintain catheter patency, reduces the risk of clots that could harbor bacteria, and ensures that the line remains free from foreign particles or biofilm buildup, which are factors that can contribute to infection. Regular flushing also promotes the continued integration of aseptic technique, which is crucial in preventing infection during catheter use.

Although other options may seem related to catheter management, they do not directly align with best practices for infection prevention. Changing IV lines at set intervals might not necessarily correlate with improved infection rates, as evidence suggests that maintaining lines longer is acceptable when proper protocols are employed and the lines are free of visible contamination. Using larger gauge catheters can lead to increased trauma and risk of infection, as they may create larger entry points and potentially disrupt surrounding tissues. In contrast, selecting appropriate access points, such as avoiding the femoral veins when possible, is advised due to the higher risk of infection associated with this anatomical location.

Therefore, the practice of regularly flushing IV lines with saline, as a measure to avoid infection by maintaining sterility and preventing occlusions or biofilm formation, stands out as the most
