The REPEAT RATE for inexperienced or careless x-ray personnel is equal to or greater than which percentage?

• A. 2%
• B. 5%
• C. 25%
• D. 10%

Answer: (D)

Repeat rate is the proportion of radiographic images that must be retaken due to technique errors. Inexperienced or careless personnel tend to have higher repeat rates because of common issues like poor patient positioning, incorrect exposure factors, motion, or inadequate collimation. When that repeat rate is around 10% or higher, it signals a level of technique deficiency that typically prompts targeted training and quality assurance interventions. The smaller figures (2% or 5%) would reflect much better performance, while 25% would be an unacceptably high rate; 10% strikes a practical benchmark for identifying and addressing underlying problems. Reducing repeats helps protect patients from unnecessary radiation and improves overall workflow.
