Certified Registered Nurse Infusion

The correct answer highlights infiltration as the most frequent complication associated with peripheral IV catheters. Infiltration occurs when the IV catheter dislodges from the vein or punctures through the vein wall, allowing the infusion fluid to enter the surrounding tissue instead of the bloodstream. This situation can lead to swelling, discomfort, and potential skin damage in the area around the catheter. Understanding that infiltration is a common issue is crucial for healthcare practitioners because it emphasizes the importance of proper catheter placement and continuous monitoring of the IV site. By being vigilant about signs of infiltration, practitioners can intervene promptly to avoid complications. While phlebitis, tissue necrosis, and air embolism are recognized complications associated with peripheral IV catheters, they occur less frequently compared to infiltration. Phlebitis is characterized by inflammation of the vein, often due to infection or irritation from the IV solution; tissue necrosis may result from complications related to administering caustic substances; and air embolism involves air entering the bloodstream, a rare but serious condition. Understanding these distinctions helps in managing and preventing complications related to IV therapy effectively.
