The repeat rate for inexperienced or careless x-ray personnel is equal to or greater than what percentage?

• A. 2%
• B. 10%
• C. 5%
• D. 25%

Answer: (B)

Repeating a radiograph happens when technique errors—such as incorrect positioning, wrong exposure factors, patient motion, or poor shielding—necessitate a second image. When inexperienced or careless radiographers perform exams, these errors occur more often, so the repeat rate tends to be higher. A threshold of ten percent or more is used in training contexts to flag that a student or new staff member is producing a noticeable number of repeats, indicating a need for closer supervision and extra technique training. Keeping repeats below this level helps minimize patient dose and improves workflow. Percentages like two or five percent are typically too low for identifying issues with inexperienced personnel, while a rate as high as twenty-five percent would signal a severe problem.
