Which of the following is NOT a function of Quality Control (QC) in bone densitometry?

• A. Examining the functionality of the machine
• B. Detecting and addressing mechanical failures
• C. Verifying patient comfort during procedures
• D. Assessing the accuracy and precision of the machine

Answer: (C)

In the context of bone densitometry, Quality Control (QC) encompasses several critical functions aimed at ensuring the reliability and accuracy of the diagnostic equipment. Among these functions, examining the functionality of the machine, detecting and addressing mechanical failures, and assessing the accuracy and precision of the machine are all integral aspects of QC procedures.

Verifying patient comfort during procedures, however, falls outside the primary scope of QC. While ensuring patient comfort is certainly important in a clinical setting, it is not a function of the formal QC processes that focus on the technical performance and reliability of the machine. QC is mainly concerned with the device's functionality, the detection of issues or failures, and maintaining standards of accuracy and precision to ensure that the results of bone density assessments are dependable. Thus, it can be understood why patient comfort does not align with the core objectives of Quality Control in this context.
