Allergic reactions to contrast during the procedure are a recognized risk. Which option reflects this risk?

• A. Allergies to contrast
• B. Hypertension
• C. Hyperglycemia
• D. Improved hearing

Answer: (A)

Allergic reactions to contrast media are a recognized risk in procedures that use contrast to visualize the vessels. Iodinated contrast can trigger hypersensitivity reactions, ranging from mild symptoms like itching or hives to severe anaphylaxis. The other options—hypertension, hyperglycemia, or improved hearing—do not reflect this allergy risk, while the focus here is specifically on adverse immune responses to the contrast agent.
