Question: 1 / 130

What type of complication can result from the administration of negative contrast agents?

Shock

Seizures

Congestion

Air emboli

The administration of negative contrast agents, such as air or gas, can lead to the formation of air emboli. Negative contrast agents are typically utilized to enhance the visibility of structures during imaging procedures, especially in certain types of studies like gastrointestinal imaging. When these agents are inadvertently introduced into the vascular system, they can create air bubbles that may travel through the bloodstream, leading to an air embolism.

Air emboli can block blood vessels, causing potential complications such as ischemia or infarction in various organs, depending on the location of the obstruction. This is a serious condition as it can lead to complications like stroke, respiratory distress, or even death if not promptly managed.

In contrast, the other options, while they may represent serious conditions, are not typically associated with the administration of negative contrast media. Shock, seizures, and congestion may arise from different pathological mechanisms or complications unrelated to negative contrast use. Focusing on the specific mechanism by which negative contrast agents can lead to air embolism is critical for understanding the risks involved in their administration.
