A nurse is collecting data from a client who is receiving IV therapy. The nurse suspects fluid infiltration. Which of the following findings should the nurse expect at the insertion site?

A. Erythema: Erythema, or redness, is more commonly associated with phlebitis, an inflammation of the vein, rather than infiltration. While some redness may occur, it is not the primary or expected finding when infiltration is present. B. Blood: The presence of blood at the insertion site may indicate a bleeding or hematoma issue but is not a typical sign of infiltration. Infiltration involves fluid, usually IV solution, leaking into surrounding tissue, not blood leaking out of the vein. C. Edema: Edema at the insertion site is a hallmark sign of infiltration. When IV fluid escapes into the surrounding tissue instead of remaining in the vein, it causes localized swelling, coolness, and often discomfort or tightness around the insertion area. D. Pruritus: Pruritus, or itching, is not a typical manifestation of infiltration. It may be seen with allergic reactions to IV medications or materials, but infiltration primarily presents with swelling, coolness, and sometimes blanching of the skin.
