ARRT Patient Care Practice Exam

Possible side effects of an iodinated contrast medium that is administered intravenously include all of the following except:

1. Warm, flushed feeling

2. Rash and hives

3. Altered taste

4. All of the above

The correct answer is: Rash and hives

When assessing the potential side effects of an iodinated contrast medium, it is essential to acknowledge that various responses can occur upon administration. A warm, flushed feeling is a common experience due to the rapid infusion of the contrast agent and the body's response to the heat generated during the process. Altered taste is also a noted side effect, as the administration of iodinated contrast can interact with the body's sensory receptors in a way that temporarily disturbs taste perception. While rash and hives can occur as allergic reactions to substances in some individuals, they are less frequently associated directly with the administration of iodinated contrast. Instead, the flushed sensation and altered taste are more typical reactions. Therefore, the correct answer reflects that rash and hives are not considered standard side effects of intravenous iodinated contrast media, making them the exception among the listed options.
