CAMRT Radiography Practice Exam

In the event of an allergic reaction post-contrast media administration, what is the first step an MRT should take?

1. Administer antihistamines

2. Call for emergency assistance

3. Monitor vital signs

4. Notify the physician

The correct answer is: Call for emergency assistance

In the situation of an allergic reaction following the administration of contrast media, the first step an MRT should take is to call for emergency assistance. This immediate action is crucial because allergic reactions can range from mild to severe, potentially progressing rapidly to life-threatening conditions such as anaphylaxis. By calling for emergency assistance, the MRT ensures that the proper medical response team is alerted and can provide necessary interventions without delay. While administering antihistamines, monitoring vital signs, or notifying the physician are essential subsequent steps in managing allergic reactions, they do not replace the urgency of calling for help. Prompt access to emergency care and resources is vital to address any developing complications effectively. Therefore, the priority in such a scenario is to ensure that assistance is on the way as soon as an allergic reaction is recognized.
