Which of the following can be a reaction to iodinated contrast agents?

The correct answer is that all the listed reactions can occur in response to iodinated contrast agents. Iodinated contrast agents are commonly used in imaging procedures, and they can provoke various allergic reactions. Sneezing, itching, and hoarseness are all manifestations of allergic responses.

Sneezing is a reflex action that can occur due to a triggering irritant, while itching is a common symptom of allergic reaction affecting the skin. Hoarseness can occur if there is swelling in the throat or irritation of the airways, which may also result from an allergic response. These symptoms reflect the body’s immune system reacting to the agent, indicating different degrees of hypersensitivity.

Understanding that all these reactions can occur highlights the importance of monitoring patients after administering iodinated contrast agents and being prepared for potential allergic reactions.
