Each of the following statements regarding retake radiographs is correct EXCEPT one. Which one is the EXCEPTION?

a. All errors create a need to re-expose the patient.
b. If one radiograph in a set of bitewings is overlapped, it should be determined whether adjacent radiographs image the area adequately.
c. Determining when a retake is necessary will keep radiation exposure to a minimum.
d. All errors reduce the quality of the radiograph.

a. Not all errors create a need to re-expose the patient. Two examples of this are when the error does not affect the area of interest and when the error affects only one radiograph in a series, where the area of interest can be viewed in an adjacent radiograph.
