During an infusion of an antineoplastic medication, what symptom at the IV site warrants immediate attention?

During an infusion of an antineoplastic medication, it is crucial to monitor the IV site closely for any signs of complications. Swelling, pain, and redness at the IV site can indicate problems such as infiltration, extravasation, or phlebitis.

Swelling can signify that the fluid is not infusing into the vein properly, potentially leading to local irritation or damage to surrounding tissues. Pain may indicate inflammation or issues with the infusion, while redness can suggest infection or irritation of the vessel. Each of these symptoms is a warning sign that could lead to more severe complications if not addressed promptly.

Since any one of these symptoms can represent a serious issue, all of them collectively warrant immediate medical attention to ensure patient safety and to prevent adverse outcomes associated with the administration of antineoplastic medications.
