What action should a radiographer take if a patient exhibits sweating, wheezing, and throat tightness after iodinated contrast media?

The correct action in this situation is to inform the radiologist and nursing staff. This response is critical because the symptoms of sweating, wheezing, and throat tightness indicate a potentially serious reaction to iodinated contrast media, which could be anaphylactic in nature.

By notifying the radiologist and nursing staff, the radiographer ensures that medical professionals who are trained to manage allergic reactions can respond quickly with appropriate interventions. This may include monitoring the patient's vital signs, administering medications like antihistamines or epinephrine, and providing necessary supportive care.

Taking immediate action with experienced personnel is essential in managing adverse reactions. Performing a CT scan, administering antihistamines independently, or continuing with the procedure could exacerbate the patient's condition and delay necessary treatment. Knowing when to escalate care is a fundamental aspect of patient safety in radiology and medical practice.
