Which of the following is a common sign of IV infiltration?

Localized swelling is a common sign of IV infiltration. When IV infiltrates occur, the fluid intended for the bloodstream leaks into the surrounding tissues. This leads to edema or swelling in the area around the IV site, as the body's tissues accumulate the excess fluid.

While tightness around the IV site can occur, it is more indicative of phlebitis or thrombophlebitis rather than infiltration itself. Signs such as dry skin and skin blanching may not directly correlate with infiltration and are less specific to this complication. By recognizing localized swelling, healthcare providers can take prompt action to address the infiltration, ensuring patient safety and comfort.
