Using iodinated contrast media can lead to a range of side effects, with nausea and vomiting being among the most common reactions. This occurs due to the osmotic effects of the contrast agent and the body's response to it. Iodinated contrast media can stimulate the gastrointestinal tract, resulting in discomfort and potential vomiting after administration.

In contrast to the other choices, improved image clarity is a benefit of using the contrast, not a side effect. Decreased heart rate and increased sensitivity to light are not typical reactions associated with iodinated contrast media. This makes nausea and vomiting a significant and notable concern for patients and healthcare providers when administering such media for imaging procedures.
