Under the repeat policy, which statement is true?

• A. Repeats may be performed at the discretion of the student.
• B. Repeats require approval by the supervising radiographer but no presence during the repeat.
• C. Unsatisfactory radiographs shall be repeated only in the physical presence of a qualified radiographer, regardless of the student's level of competency.
• D. Repeats are prohibited after hours.

Answer: (C)

Direct supervision during repeats protects patient safety and ensures correct imaging technique. The statement that an unsatisfactory radiograph must be repeated only in the physical presence of a qualified radiographer correctly applies this principle, because a qualified radiographer can verify positioning, exposure parameters, and shielding before the repeat is made. This holds regardless of the student’s level of competency, since the safety and technical checks come from a qualified observer. The other options conflict with supervision requirements or common practice: repeats aren’t left to a student’s discretion, they can’t be performed without the supervisor present, and after-hours policies are not universally prohibitive when supervision is maintained.
