Introduction
This quiz collection on Corrective & Preventive Action (CAPA) is designed specifically for M.Pharm students studying Documentation & Regulatory Writing. It emphasizes practical understanding of CAPA systems within pharmaceutical quality management — covering root-cause analysis, CAPA lifecycle, regulatory expectations, risk-based prioritization, documentation practices, and effectiveness evaluation. Questions range from fundamentals to advanced regulatory and operational considerations that pharmacists encounter during audits, deviations, OOS investigations, supplier management and continual improvement activities. Use these MCQs to test retention, prepare for exams and inspections, and sharpen skills needed to design, document and assess CAPA processes that ensure product quality and patient safety.
Q1. Which statement best describes the primary objective of a CAPA system?
- To document all deviations for regulatory inspections
- To eliminate recurring quality problems by identifying and addressing root causes

- Control chart
- Fishbone (Ishikawa) diagram
- Pareto chart
- Gantt chart
Correct Answer: Fishbone (Ishikawa) diagram
Q3. What distinguishes a corrective action from a preventive action?
- Corrective actions are always documented; preventive actions are not
- Corrective actions address detected nonconformities; preventive actions address potential nonconformities
- Corrective actions are regulatory responsibilities; preventive actions are optional
- Corrective actions are short-term fixes; preventive actions are always long-term
Correct Answer: Corrective actions address detected nonconformities; preventive actions address potential nonconformities
Q4. During CAPA planning, what is the purpose of risk assessment?
- To determine how much documentation is required
- To prioritize actions based on potential impact on product quality and patient safety
- To assign blame to specific departments
- To set budgetary limits for CAPA implementation
Correct Answer: To prioritize actions based on potential impact on product quality and patient safety
Q5. Which of the following is a common method for root cause analysis in CAPA investigations?
- 5 Whys technique
- Statistical process control only
- Blame allocation matrix
- Batch-to-batch comparison without analysis
Correct Answer: 5 Whys technique
Q6. Which element is essential in a CAPA record to demonstrate regulatory compliance?
- Names of all employees in the department
- Detailed root cause analysis, corrective/preventive actions, implementation dates, and effectiveness verification
- Generic statement that the issue was resolved without details
- Only the final closure date of the CAPA
Correct Answer: Detailed root cause analysis, corrective/preventive actions, implementation dates, and effectiveness verification
Q7. What is the difference between verification and validation of CAPA effectiveness?
- Verification ensures the action was implemented; validation confirms the action prevented recurrence and meets intended outcome
- Verification is done by regulators; validation is done by manufacturers only
- Verification refers to documentation accuracy; validation refers to employee training
- There is no difference; the terms are interchangeable
Correct Answer: Verification ensures the action was implemented; validation confirms the action prevented recurrence and meets intended outcome
Q8. Which regulatory requirement emphasizes CAPA systems in pharmaceutical quality management?
- ICH Q10 Pharmaceutical Quality System
- ISO 9001 only
- Good Laboratory Practice (GLP) guidance
- Pharmacopoeial monographs
Correct Answer: ICH Q10 Pharmaceutical Quality System
Q9. In CAPA, what is a “containment action”?
- An action to permanently change the system
- An immediate action to limit impact or prevent escalation while root cause is being investigated
- An administrative delay in CAPA implementation
- A statistical method to verify long-term trends
Correct Answer: An immediate action to limit impact or prevent escalation while root cause is being investigated
Q10. Which metric is most useful to monitor CAPA program performance?
- Number of CAPAs opened during audits only
- CAPA closure rate and rate of CAPA recurrence over time
- Number of pages in each CAPA file
- Number of people involved in CAPA meetings
Correct Answer: CAPA closure rate and rate of CAPA recurrence over time
Q11. When should a CAPA be initiated in response to a customer complaint about product quality?
- Only if the complaint is repeated more than three times
- When investigation indicates a possible system or product issue that could recur
- Only after a regulatory inspector requests it
- When the complaint is acknowledged by the sales department
Correct Answer: When investigation indicates a possible system or product issue that could recur
Q12. Which of the following best describes a “root cause” in CAPA investigations?
- The immediate technician who noted the deviation
- The underlying fundamental issue that, if corrected, prevents recurrence of the problem
- An incidental event unrelated to the failure
- The corrective action chosen to fix the problem
Correct Answer: The underlying fundamental issue that, if corrected, prevents recurrence of the problem
Q13. Which CAPA action is most appropriate for addressing a supplier-related quality failure?
- Terminate all supplier contracts immediately
- Initiate supplier CAPA including root cause, corrective actions with timelines, and effectiveness checks; consider supplier audit
- Ignore supplier input and rework products internally
- Only document the event without supplier involvement
Correct Answer: Initiate supplier CAPA including root cause, corrective actions with timelines, and effectiveness checks; consider supplier audit
Q14. Which practice ensures CAPA documentation is inspection-ready?
- Maintain minimal information to reduce file size
- Maintain a clear audit trail with dates, responsible persons, decisions, evidence of implementation and effectiveness results
- Store CAPA evidence only in emails without summary
- Use hand-written notes without sign-offs
Correct Answer: Maintain a clear audit trail with dates, responsible persons, decisions, evidence of implementation and effectiveness results
Q15. What role does trending analysis play in CAPA?
- Trending is only useful for marketing purposes
- It helps detect patterns or emerging issues that may require preventive actions
- It replaces the need for root cause analysis
- Trending delays immediate corrective actions
Correct Answer: It helps detect patterns or emerging issues that may require preventive actions
Q16. Which statement about CAPA effectiveness checks is true?
- Effectiveness checks can be immediate and also longitudinal to confirm sustained improvement
- Effectiveness checks should be skipped for minor CAPAs
- Only qualitative feedback is acceptable for effectiveness
- Effectiveness checks are only necessary before CAPA closure
Correct Answer: Effectiveness checks can be immediate and also longitudinal to confirm sustained improvement
Q17. In pharmaceutical CAPA, when is revalidation required as part of corrective action?
- When changes affect processes or controls that impact product quality and require documented proof of performance
- Always, for every CAPA regardless of scope
- Never; revalidation is a separate activity
- Only for administrative changes to SOPs
Correct Answer: When changes affect processes or controls that impact product quality and require documented proof of performance
Q18. Which CAPA governance practice supports timely and effective implementation?
- Assign CAPA ownership to a single accountable person and a cross-functional team, with defined timelines and escalation routes
- Allow CAPA owners to set timelines without oversight
- Keep CAPA decisions informal and undocumented
- Postpone review until the next annual meeting
Correct Answer: Assign CAPA ownership to a single accountable person and a cross-functional team, with defined timelines and escalation routes
Q19. How should CAPA relate to change control?
- CAPA and change control are unrelated systems
- CAPA may result in change control submissions when corrective/preventive actions require formal changes to processes, specifications, or documentation
- Change control should always precede any CAPA
- Change control only applies to IT systems, not CAPA outcomes
Correct Answer: CAPA may result in change control submissions when corrective/preventive actions require formal changes to processes, specifications, or documentation
Q20. Which of the following is a sign of an ineffective CAPA program?
- Declining number of product complaints and fewer deviations
- Frequent recurrence of the same issues and many overdue CAPAs
- Well-documented root cause analyses and regular effectiveness reviews
- Active trending and risk-based prioritization of CAPAs
Correct Answer: Frequent recurrence of the same issues and many overdue CAPAs
