Which statement about IV site assessment is correct?

• A. Redness, swelling, and heat are not evaluated; IV site needs no routine assessment.
• B. Redness alone is assessed with IV therapy.
• C. IV sites require no frequent monitoring.
• D. Redness, swelling, and heat should be evaluated, and the site should be assessed at least every 4 hours and before use.

Answer: (D)

Regular IV site assessment is essential to catch complications like phlebitis, infiltration, or infection early. Redness, swelling, and warmth are all indicators of irritation or inflammation around the vein, and evaluating all three provides a complete picture rather than looking for just one sign. Before starting an IV and before each use, inspect the site for patency and any changes. During therapy, monitor at least every 4 hours to detect evolving issues such as increasing tenderness, swelling, or drainage, and discontinue or reposition the catheter if signs of infiltration or phlebitis appear. This proactive, ongoing assessment helps prevent complications and keeps the IV therapy effective.
