After service or repair of exposure devices, which information should be documented?

• A. Repair cost and supplier contact only.
• B. Calibration results, date, technician, device model, exposure settings changes, and sign-off.
• C. Last service date and device color only.
• D. Battery level and software version only.

Answer: (B)

After service or repair, you must keep documentation that provides a complete trace of the verification and changes made to the exposure device. The best answer includes calibration results, date, technician, device model, exposure settings changes, and sign-off because it confirms the device is accurate, accountability is established, and the current configuration is recorded. Calibration results show the output matches specifications, ensuring patient dose and image quality stay within safe limits. Recording the date and device model ties the record to the exact instrument and service event, while noting the technician identifies who performed the work. Any changes to exposure settings must be documented to show what was modified and what is currently in use, facilitating future QA comparisons. The sign-off indicates formal approval to return the device to clinical use. Records that omit calibration, verification, or formal approval fail to demonstrate that the device was properly validated after service.
