NCLEX RN Practice Question

Changing the dressing with attention to aseptic technique is essential to preventing catheter-related bloodstream infections (CRBSIs), which are a major complication of PICC lines. This intervention minimizes the introduction of pathogens at the insertion site. While flushing the catheter maintains its function, it primarily prevents occlusion rather than addressing infection prevention. Inspecting the site for signs of infection is valuable for early detection but does not actively reduce the risk of complications. Ensuring the catheter hub is clamped helps prevent air embolism but has a more limited role in overall complication prevention compared to maintaining sterility during dressing changes.
