What do we call medication or contrast that is introduced into the tissues surrounding the vein?

1. Infiltration

2. Inflammation

3. Claudication

4. Extravasation

The correct answer is: Extravasation

The term that refers to medication or contrast that is introduced into the tissues surrounding the vein is extravasation. This occurs when the substance intended for administration into the bloodstream leaks out of the vein and into the surrounding tissues. Extravasation can lead to various complications, including swelling, pain, and, in some cases, tissue damage, depending on the medication or contrast used. It is particularly important for healthcare professionals to monitor for signs of extravasation during intravenous administrations, as prompt recognition and intervention can help mitigate any potential adverse effects. While infiltration can also refer to the unintended administration of a substance into surrounding tissues, it often implies that fluid is entering the tissues without the same level of concern for complications that can arise from more aggressive substances. Inflammation refers to the body’s response to injury or irritation and doesn’t specifically address the issue of drug administration. Claudication is related to cramps or pain due to inadequate blood flow, particularly in the legs, and is unrelated to the topic of intravenous medication administration.
