Which of the following is NOT considered a main IV complication?

• A. Arterial thrombosis of the cannulated artery
• B. Infection at the site
• C. Development of superficial thrombophlebitis
• D. IV site leaking interstitially

Answer: (A)

The question tests which issues are typical complications of a peripheral IV line. Peripheral IV therapy places a catheter in a vein, so the main concerns are problems related to the vein and the infiltration of fluids into surrounding tissues. Infection at the site reflects contamination or colonization of the skin and catheter. Development of superficial thrombophlebitis is inflammation and clotting in the superficial vein caused by irritation from the cannula or infused medications. IV site leaking interstitially, or infiltration, happens when fluid leaks into surrounding tissue, causing swelling and discomfort and possibly tissue injury.

Arterial thrombosis of the cannulated artery is not a standard IV complication because it implies cannulating an artery, which is not routine peripheral IV practice. Arterial lines are a different procedure with their own risks, including arterial occlusion and distal ischemia, but they’re not part of typical IV therapy. That’s why this option is not considered a main IV complication.
