Tell me about a time you made a mistake at work and how you handled it.
What they are checking: Whether they report errors honestly, which is essential for patient safety culture.
What would you do
A patient starts having a reaction to contrast during the scan. What do you do?

What they are checking: Whether they use calm explanation and good communication to keep the patient still and comfortable.
About the work
