Which of the following is a sign of infiltration at an IV site?

A sign of infiltration at an IV site is characterized by pallor and swelling. When an IV infiltrates, fluid leaks out of the vein and into the surrounding tissue, leading to swelling in the area. This swelling occurs as the fluid accumulates and the body's normal vascular mechanisms are disrupted. Additionally, pallor may be observed due to reduced blood flow as a result of the extravasation.

Other signs may vary, but the combination of pallor and swelling is a key indicator that the IV fluids are not being administered effectively into the bloodstream and are instead accumulating in the surrounding tissue. Recognizing these signs quickly is critical in preventing further complications and ensuring proper patient care.
