Which complication of a simple venous catheter requires the nurse to assess the history of catheter use?

• A. Catheter Rupture
• B. Catheter Migration
• C. Catheter Dislodgement
• D. Catheter Lumen Occlusion

Answer: (D)

The main idea is that lumen occlusion is closely tied to how the catheter has been used over time. When a catheter has been accessed repeatedly or left in place for an extended period, clots and fibrin can form inside the lumen, and meds or IV fluids can precipitate deposits, all of which narrow or block the channel. That history of use helps explain why occlusion occurs and why it’s the complication most likely connected to prior catheter use. A lumen occlusion presents when you try to flush or aspirate and meet resistance or a complete inability to pass saline through the catheter. If a patient has had frequent access, multiple dwellings, or inconsistent locking flushes, the risk for thrombus formation within the lumen rises, making occlusion more likely. To assess this risk, the nurse reviews how long the catheter has been in place, how often it has been accessed, what flush or lock solutions were used, and whether any medications were administered through the line that could precipitate blockage. In contrast, catheter rupture, migration, or dislodgement are more about mechanical issues or physical movement rather than cumulative use history, so they don’t hinge on past catheter use to the same extent.
