Which of the following describes a moderate physiologic reaction to contrast media?

The description of a moderate physiologic reaction to contrast media is characterized by protracted nausea and vomiting. These symptoms indicate a reaction that, while distressing and uncomfortable, is not considered life-threatening or severe. Moderate reactions typically involve symptoms that require medical observation or intervention but do not necessitate emergency treatment.

In the context of moderate reactions, nausea and vomiting can occur as the body reacts to the foreign substances in the contrast media, but these symptoms usually do not escalate to more severe complications like anaphylaxis or serious cardiovascular events. Recognizing such reactions is important for healthcare professionals to ensure proper patient monitoring and care.
