Question: 1 / 1100

If 6 x-rays are taken and 2 are repeated, what is the repeat rate?

20%

33%

To determine the repeat rate, you can use the formula:

\[

\text{Repeat Rate} = \frac{\text{Number of Repeats}}{\text{Total X-rays Taken}} \times 100

\]

In this scenario, there are 6 x-rays taken in total, with 2 of those needing to be repeated. Plugging the numbers into the formula:

\[

\text{Repeat Rate} = \frac{2}{6} \times 100 = \frac{200}{6} \approx 33.33\%

\]

When rounded, this value corresponds to approximately 33%. This indicates that 33% of the x-rays taken were repeats, providing a clear understanding of how frequently initial attempts did not meet the required quality standards.

The repeat rate is essential in evaluating the efficiency and quality of radiographic practices. A high repeat rate can indicate problems in technique, patient positioning, or equipment, which ultimately can affect patient safety and increase exposure time.
