RAC Quality Systems and GMP Questions and Answers

Question 1

An internal audit at a medical device manufacturer reveals that three separate production batches failed final inspection for the same dimensional specification over the past two months. The issue was documented, and the non-conforming products were scrapped each time. According to 21 CFR 820.100, which of the following actions is now required?

Accepted Answer

Initiate a corrective action to investigate the root cause of the failures.

Answer

The recurring nature of the non-conformance indicates a systemic issue that requires a formal Corrective and Preventive Action (CAPA) investigation to find and eliminate the root cause, as required by 21 CFR 820.100. Scrapping the product is a 'correction,' but it does not prevent recurrence. Retraining may be part of a corrective action, but it should not be implemented until a root cause is identified. A field correction is not indicated as the product was not distributed.

Question 2

For a pharmaceutical product manufactured and distributed in the United States, which document provides the complete, official manufacturing history of a finished batch, including all production and control records?

Accepted Answer

The Batch Production and Control Record (BPCR)

Answer

Per 21 CFR 211.188, the Batch Production and Control Record (BPCR) is the comprehensive record containing all the data and history of the manufacture of a single batch. The Master Batch Record is the approved template or recipe. A Drug Master File is a submission to the FDA containing confidential information. An SOP is a general procedure, not a batch-specific record.

Question 3

A medical device company is finalizing the development of a new infusion pump. Which of the following activities BEST satisfies the requirement for Design Validation under 21 CFR 820.30(g)?

Accepted Answer

Simulating clinical use with intended users in a controlled environment to confirm user needs are met.

Answer

Design validation's purpose is to ensure the finished device conforms to defined user needs and intended uses under actual or simulated use conditions. Simulating clinical use with actual users directly tests this. Software unit testing and motor performance testing are examples of design *verification*—confirming the design output meets the design input specifications. Compiling the DMR is a documentation activity.

Question 4

During a scheduled management review, the Head of Quality presents data showing a negative trend in supplier performance, specifically an increase in late deliveries of a critical component. According to the Quality System Regulation (21 CFR 820.20), what is the MOST appropriate output of this review?

Accepted Answer

An assignment of an action item to investigate the supplier issue and a commitment of resources to address it.

Answer

Management review, as defined in 21 CFR 820.20(c), requires reviewing the suitability and effectiveness of the quality system and making decisions or assigning actions where needed. The primary role of management is to assess data and assign actions and resources to ensure the effectiveness of the quality system. Simply finding a new supplier is premature, increasing stock is a temporary fix, and waiting is not proactive.

Question 5

Under US GMP for pharmaceuticals (21 CFR Part 211), which of the following responsibilities and authorities is uniquely assigned to the Quality Control Unit (QCU)?

Accepted Answer

The final disposition (approval or rejection) of all drug product batches.

Answer

21 CFR 211.22 explicitly states that the Quality Control Unit shall have the responsibility and authority to approve or reject all components and drug products. While the QCU reviews and approves other documents and activities, the final authority to release or reject a batch rests solely with them.
