Which action is typically taken when documenting QC actions to maintain compliance?

• A. Delete the failed control data.
• B. Ignore the QC result if outside limit.
• C. Investigate root cause and implement corrective action.
• D. Only document if the supervisor asks.

Answer: (C)

When QC actions are documented, the goal is to create a clear, traceable record of how quality issues were handled to ensure patient safety and meet regulatory requirements. The best approach is to investigate the root cause of the QC failure and implement corrective actions to prevent recurrence. This means documenting what was found during the investigation, what corrective steps were taken, and how you verified that the issue is resolved (and whether any preventive measures are needed). Deleting data or ignoring results undermines compliance and makes audits difficult, and documentation should happen as part of routine quality practice, not only if someone asks.
