Define "phlebitis" and its potential risks.

Phlebitis is defined as the inflammation of a vein, commonly occurring as a complication of intravenous therapy. This condition can arise from various factors, including mechanical irritation from the IV catheter, chemical irritation from the intravenous solution, or bacterial infection.

The importance of identifying phlebitis lies in its potential risks. If left untreated, inflammation can lead to further complications such as local infection, which might spread, and the development of thrombophlebitis, where a blood clot forms in the inflamed vein. This can not only cause pain and discomfort but can also escalate to more severe conditions like deep vein thrombosis (DVT) or pulmonary embolism if clots dislodge and enter the bloodstream.

Recognizing these risks emphasizes the importance of careful monitoring and proper technique when establishing and maintaining intravenous access.
