Which of the following symptoms is NOT associated with mild contrast allergic reactions?

• A. Mild urticaria
• B. Facial edema
• C. Nasal stuffiness
• D. Scratchy throat

Answer: (B)

Facial edema is indeed not typically associated with mild contrast allergic reactions. Mild allergic reactions to contrast media often present with symptoms such as urticaria, which is characterized by hives or itchy welts on the skin. Nasal stuffiness and a scratchy throat may also occur as part of a mild allergic response, often due to histamine release, which can lead to respiratory symptoms.

In contrast, facial edema usually indicates a more severe allergic reaction, known as angioedema, which involves deeper layers of the skin and could affect the face, lips, or throat. This type of reaction is considered more serious than the mild reactions commonly observed and could lead to difficulty breathing or swallowing. Therefore, it is the symptom that stands out as not being associated with mild allergic reactions to contrast media.
