Which of the following is a common risk factor for a contrast media reaction?

Asthma is identified as a common risk factor for reactions to contrast media primarily because individuals with asthma often have heightened sensitivity and can develop allergic-like responses to various substances, including contrast agents. The underlying mechanism may involve bronchial hyperreactivity and a predisposition to allergic reactions, which can result in severe respiratory issues following exposure to these contrasting agents. Thus, when administering contrast media, it is essential for healthcare providers to be particularly vigilant when treating patients with a history of asthma, as they may require additional monitoring and premedication to mitigate potential adverse effects.

In contrast, although conditions like hypertension, heart disease, and diabetes can complicate a patient's overall health and response to treatment, they are not typically associated with the same level of increased risk for contrast media reactions as asthma.
