CAMRT Radiography Practice Exam

If extravasation occurs during an injection, what should be the immediate response?

1. Continue the injection as planned

2. Stop the injection and apply a cool compress

3. Stop the injection and apply a warm compress

4. Notify the physician only

The correct answer is: Stop the injection and apply a warm compress

When extravasation occurs during an injection, it indicates that the contrast material, medication, or fluid has leaked outside of the intended vascular space into the surrounding tissue. The immediate response should focus on minimizing tissue damage and alleviating discomfort. Applying a warm compress is beneficial in this scenario because warmth can help to increase blood flow to the area, which may aid in reabsorbing the leaking fluid and reducing swelling. Warmth can also provide comfort to the patient and alleviate pain. It is essential to stop the injection immediately to prevent further leakage and potential damage to the surrounding tissues. On the other hand, continuing the injection as planned could exacerbate the situation, leading to increased damage and complications. Applying a cool compress might be more suitable for certain types of injuries, such as inflammation or reduction of swelling, but in the case of extravasation with contrast material, warmth is more appropriate for encouraging circulation and healing. Notifying the physician is also necessary, but the immediate response should focus on managing the situation at hand, which includes stopping the injection and applying the correct type of compress.
