Which of the following describes phlebitis during IV therapy?

Phlebitis is specifically defined as the inflammation of a vein, particularly one that has been used for intravenous therapy. This condition can occur due to various factors such as irritation from the catheter, the solution being infused, or the mechanical trauma caused by the insertion of the IV needle. Recognizing phlebitis is crucial for patient safety and comfort, as it can lead to complications if not addressed promptly. Proper management includes identifying early signs and symptoms such as redness, swelling, warmth, and pain at the IV site.

The other options, while related to IV therapy complications, do not accurately describe phlebitis. Leakage of IV fluids refers to extravasation, which involves fluid escaping into the surrounding tissue rather than the vein itself. Powerful muscle contraction pertains more to muscular responses rather than vein inflammation, and accumulation of blood at the IV site typically indicates a hematoma rather than phlebitis. Understanding these distinctions is essential for effective IV therapy practice and ensuring optimal patient outcomes.
