How is infiltration defined in the context of IV therapy?

In the context of IV therapy, infiltration is specifically defined as the unintended administration of IV fluid into the surrounding tissue rather than directly into the bloodstream. This occurs when the IV catheter becomes dislodged from the vein, or if there is a malfunction with the catheter that allows fluid to escape from the vein into the surrounding tissues.

Infiltration can lead to swelling, pain, and tissue damage at the site of the infusion, making it a significant concern in intravenous procedures. It is important for healthcare providers to monitor IV sites regularly to identify signs of infiltration early, as timely intervention can prevent complications associated with tissue swelling and damage.

The other options describe different aspects of IV therapy that do not align with the definition of infiltration. Proper administration of IV fluids pertains to the accurate delivery of fluids into the bloodstream, while the occurrence of a blood clot refers to thrombosis, and an allergic reaction signifies an immune response to substances in IV fluids. Thus, none of these alternatives capture the specific definition of infiltration in IV therapy.
