If daily quality control fails, what is your recommended first action?

• A. Change the equipment settings
• B. Repeat the scan
• C. Call for technical support
• D. Document the failure

Answer: (B)

When daily quality control measurements indicate a failure, the recommended first action is to repeat the scan. This approach allows for the verification of the initial results and helps determine if the failure was a one-time anomaly or indicative of a more persistent issue. Repeating the scan ensures that the data collected is accurate and reliable, which is crucial for patient safety and diagnosis.

In the event of quality control failure, it is often possible that environmental factors, operator error, or temporary equipment malfunctions could have influenced the initial results. By repeating the scan, you can rule out these possibilities and establish a clearer picture of the equipment's performance.

Before making changes to the equipment settings, seeking technical support, or documenting the failure, it is important to confirm that the original test results are indeed erroneous. Therefore, the act of repeating the scan is an effective and logical first step in troubleshooting quality control issues.
