Which symptom indicates a severe contrast reaction?

1. Dizziness

2. Weakness

3. Cough

4. Cardiac arrest

The correct answer is: Cardiac arrest

The presence of cardiac arrest as a symptom indicates a severe contrast reaction. In the context of contrast media used during imaging procedures, reactions can range from mild to severe. Severe reactions may include anaphylaxis, which can lead to life-threatening conditions such as cardiac arrest. Cardiac arrest is characterized by the sudden cessation of heart function, which can occur as a result of a severe allergic response or anaphylactic shock following contrast administration. This condition requires immediate medical attention and intervention, as it poses a serious risk to the patient’s life. In comparison, the other symptoms listed, such as dizziness, weakness, and cough, are generally associated with less severe reactions. While they may indicate some level of adverse reaction, they do not represent the critical and immediate threat that cardiac arrest does. Understanding these distinctions is vital for healthcare professionals to swiftly identify and respond to severe reactions, ensuring patient safety during imaging procedures.
