What mild adverse reactions can occur from administering contrast media for CTA?

1. Seizures

2. Nausea and vomiting

3. Cardiac arrest

4. Extreme confusion

The correct answer is: Nausea and vomiting

Nausea and vomiting are commonly recognized as mild adverse reactions to the administration of contrast media for CT angiography (CTA). These reactions are often due to the body’s response to the contrast agent and can occur shortly after administration. While discomforting, they typically do not indicate a severe allergic reaction and can generally be managed easily. The other reactions listed, such as seizures, cardiac arrest, and extreme confusion, are not classified as mild adverse reactions. Seizures and cardiac arrest are severe complications that can arise from more serious allergic reactions or patient-specific factors, while extreme confusion may indicate a more significant neurological event or toxicity rather than a mild reaction to contrast media. It is vital for healthcare providers to monitor for these reactions, understanding that while cases of nausea and vomiting are common and usually self-limiting, it is critical to differentiate them from more serious adverse reactions.
