Which symptoms indicate moderate contrast allergic reactions?

• A. Mild urticaria, nasal stuffiness, itchy throat
• B. Facial edema, throat tightening, wheezing
• C. Diffuse erythema, mild hypotension, nasal congestion
• D. Anaphylactic shock, severe urticaria, skin rash

Answer: (B)

Moderate contrast allergic reactions typically present with symptoms that affect the respiratory system and result in more significant physiological changes compared to mild reactions. In this case, the correct choice highlights symptoms such as facial edema, throat tightening, and wheezing. Facial edema indicates swelling that can compromise the airway, while throat tightening suggests that the patient is experiencing difficulty in swallowing or breathing, which can be a precursor to more severe reactions. Wheezing, a high-pitched whistling sound during breathing, commonly indicates bronchospasm, which is characteristic of moderate allergic responses. This understanding is critical for healthcare professionals, as recognizing these symptoms promptly is essential for managing a patient's safety during procedures requiring contrast media. Identifying these moderate reactions allows for appropriate interventions, potentially preventing progression to more severe reactions, such as anaphylactic shock. The other options present symptoms associated with varying intensities of allergic reactions, but they do not encapsulate the severity or combination of symptoms indicative of a moderate allergic response as clearly as the correct answer.
