What symptom is NOT typically associated with moderate contrast media reactions?

Moderate contrast media reactions are characterized by a range of symptoms that typically include facial edema, headache, and tachycardia. Nausea, while it can occur in various medical settings, is generally not associated with moderate reactions to contrast media.

Facial edema refers to swelling of the face, which can occur due to an allergic or anaphylactoid response to the contrast material. Headaches are also a relatively common symptom seen in individuals experiencing moderate reactions, often attributable to various physiological changes triggered by the contrast media. Tachycardia, or an elevated heart rate, can result from anxieties related to the procedure or a sympathetic response to the contrast agent and is a common finding during moderate reactions.

In contrast, nausea is more typically associated with mild reactions or as a general response to the stress of the imaging procedure rather than a direct symptom of a moderate contrast media reaction. Therefore, identifying nausea as not typical of moderate reactions helps in understanding the nuances of contrast media side effects and differentiates them from symptoms associated with mild reactions.
