B. To increase the amount of paperwork
C. To avoid identifying future problems
D. To eliminate all future risks permanently

Answer: A — To confirm whether the action successfully addressed the cause and prevented recurrence.

Explanation: A corrective action is not complete simply because it was implemented; its effectiveness should be reviewed.

Clause 8 — Management System Requirements — includes internal audits.

What is the primary purpose of an internal audit?

A. To determine whether the management system conforms to requirements and is effectively implemented
B. To punish laboratory personnel
C. To guarantee that the laboratory receives accreditation
