What describes fluid infiltration?

Fluid infiltration occurs when intravenous (IV) fluid leaks out of the vein and into the surrounding tissues. This leakage leads to swelling and can be characterized by changes in the appearance of the affected area.

In the context of the choices provided, selecting the option related to a glossy appearance in edematous gingival tissue aligns with the phenomena of infiltration. When the tissues become edematous due to the accumulation of fluid, they can take on a shiny or glossy appearance because of the increased fluid content.

This description effectively captures the essence of fluid infiltration in a tissue area. Other options may not adequately represent the mechanism or outcome related to fluid infiltration, as local redness around an IV site or swelling in the surrounding skin does not specifically denote the condition of infiltration. Additionally, bleeding at the injection site refers to a different occurrence related to vascular injury rather than the leakage of fluid into surrounding tissues. The characteristics of the affected area, such as a glossy appearance, ultimately denote the specific clinical manifestation associated with fluid infiltration.
