In what order should the following be done to discontinue a contrast media administration?

The correct procedure for discontinuing the administration of contrast media involves first placing sterile gauze over the puncture site. This action serves to immediately address the potential for bleeding, as it provides a barrier that can contain any blood at the site once the cannula is removed. Following that, elevating the extremity and applying pressure is crucial to help control bleeding until it stops completely. Finally, the cannula should be removed from the vein in a quick yet smooth manner to minimize discomfort and prevent trauma to the vein.

This order is significant because it prioritizes patient safety and effective management of the puncture site. Beginning with the gauze allows for immediate pressure application, which is essential when the cannula is removed. Elevating the extremity afterward aids in reducing venous pressure and further controls bleeding. The removal of the cannula should not occur until the puncture site is being managed effectively with gauze and pressure, ensuring that the risk of bruising or hematoma formation is minimized.
