What complication can arise from intravenous administration related to a vein?

Phlebitis is the correct answer because it specifically refers to the inflammation of a vein, which can occur as a complication of intravenous (IV) administration. When a substance is infused into a vein, it can irritate the vessel lining, leading to inflammation, redness, swelling, and pain along the vein. This condition can be particularly common if the IV site is not properly cared for or if the infusion of irritating medications occurs. The presence of phlebitis indicates that the vein has been adversely affected by the intravenous therapy.

Phlebitis can be a significant concern in a clinical setting as it may lead to more severe complications if not monitored and treated promptly. Understanding the risks associated with IV administration, including phlebitis, helps pharmacy technicians and healthcare providers implement appropriate protocols to minimize patient risks and ensure safe medication administration.

Other conditions mentioned, such as embolus and thrombus, refer to the formation of blood clots but do not specifically relate to the complications of vein inflammation that phlebitis encompasses. Toxic shock, while serious, is usually associated with specific infections or conditions and is not a direct complication of IV administration affecting the vein itself.
