Redness and tenderness on IV site led to discontinuation with restart documented due to which complication?

• A. Clotting of the IV catheter
• B. Infiltration
• C. Phlebitis
• D. Puncture of the opposite side of the vein

Answer: (C)

Redness and tenderness along the vein indicate phlebitis, an inflammation of the vein caused by the IV catheter or the infused solution. This inflammation makes the vein warm, tender, and sometimes feel like a cord under the skin, which is why the IV is often discontinued and restarted at a different site to prevent further irritation or infection. Infiltration would show swelling and cool, pale skin around the site rather than a painful, red vessel; a clot inside the catheter would more likely cause trouble with the infusion flow rather than a red, tender vein along its course; puncturing another part of the vein isn’t the typical explanation for this presentation.
