About your past
Tell me about a time a radiologist asked you to repeat or change a scan. How did you respond?
What they are checking: Whether they take feedback well and work with radiologists to get images that support an accurate diagnosis.
What would you do
This is a night shift, 9 PM to 7 AM, Thursday through Sunday at MacNeal Hospital. How do you stay sharp working nights, and how does that schedule fit your life?
What they are checking: Whether they can sustain night shift work reliably, since nights often mean fewer staff and more trauma.
A patient starts having hives and trouble breathing right after a contrast injection. What do you do?
What they are checking: Whether they recognize a contrast reaction, call for help immediately and know their role in the emergency response.
At night you may be the only CT tech when a stroke alert and a trauma come in together. How do you handle it?
What they are checking: Whether they can prioritize time-critical scans and communicate with the ED and radiologist under pressure.
A confused patient keeps moving during the scan. What do you do?
What they are checking: Whether they can get usable images safely with calm communication and help rather than repeated exposures.
About the work
Walk me through how you screen a patient before giving IV contrast.
What they are checking: Whether they check kidney function, allergies, metformin and prior reactions and follow protocol before injecting.
How do you keep radiation dose as low as reasonably achievable on a CT scan?
What they are checking: Whether they actively adjust protocols and positioning for each patient rather than running the same settings for everyone.
Tell me about the CT scanners and protocols you have worked with, including CTA and stroke imaging.
What they are checking: Whether their one to two years of experience covers the advanced scans a hospital night shift requires.
How do you handle an IV that infiltrates during a contrast injection?
What they are checking: Whether they stop the injection, assess the site, notify the right people and document correctly.
Your ARRT and IEMA license are required. How do you stay current on your credentials and continuing education?
What they are checking: Whether they manage their licensing responsibly so they are never out of compliance on the schedule.
