Which assessment tool is used to rate IV infiltration severity?

• A. INS Infiltration Scale
• B. Baxter Infiltration Scale
• C. Fitzpatrick Scale
• D. Norton Scale

Answer: (A)

In IV therapy, grading infiltration severity with a standardized tool lets you describe how serious the leakage is and decide on the right action. The tool designed for this purpose is the INS Infiltration Scale. It provides a clear range from no infiltration to severe infiltration based on observable signs such as edema, pallor or cool skin, pain, and how far the signs extend from the insertion site. Using this scale helps you know when to stop the infusion, remove the catheter, elevate the limb, and apply appropriate treatment while monitoring for complications. The other scales measure different things—Fitzpatrick classifies skin type, Norton assesses pressure ulcer risk—and while Baxter has its own infiltration references, the INS Infiltration Scale is the standard choice for rating IV infiltration severity in most guidelines.
