Introduction:
This blog provides a focused set of multiple-choice questions on the audit of the engineering department tailored for M.Pharm students studying Audits and Regulatory Compliance. The questions cover practical and regulatory aspects such as maintenance, calibration, validation of utilities, documentation practices, contractor controls, change control, risk assessment, and compliance with cGMP. Designed to deepen understanding beyond superficial points, these MCQs emphasize real-world audit observations, key performance indicators, and corrective actions that influence product quality and regulatory outcomes. Use this quiz to test knowledge, prepare for viva or examinations, and reinforce the critical role of engineering audits in maintaining compliant pharmaceutical manufacturing environments.

- Generic diagrams without test data
Correct Answer: Installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) reports
Q7. What is the primary purpose of trending maintenance and calibration data in an engineering audit?
- To create colorful graphs for management presentations
- To identify recurring failures and enable preventive corrective actions
- To justify budget increases annually
- To show that no maintenance was performed
Correct Answer: To identify recurring failures and enable preventive corrective actions
Q8. Which audit observation best represents poor contractor management?
- Contractors wear appropriate PPE and sign in/out
- No documented qualifications, no access control, and no supervision during critical area work
- Contractor work scheduled during planned shutdown
- Contractors submit invoices promptly
Correct Answer: No documented qualifications, no access control, and no supervision during critical area work
Q9. When auditing utility alarms and interlocks, what would be considered a major nonconformity?
- Alarms are configured but have documented owners and response procedures
- Interlocks are bypassed temporarily without formal approval or documentation
- Alarm setpoints are recorded in the building management system
- Alarm logs are reviewed weekly and actions documented
Correct Answer: Interlocks are bypassed temporarily without formal approval or documentation
Q10. Which KPI is most relevant for measuring engineering department effectiveness from a quality perspective?
- Number of team-building events per year
- Mean time to repair (MTTR) for critical process equipment and percentage of preventive vs corrective maintenance
- Number of suppliers contacted
- Length of service contracts with vendors
Correct Answer: Mean time to repair (MTTR) for critical process equipment and percentage of preventive vs corrective maintenance
Q11. During an audit, you find undocumented temporary repairs on a critical piping system. What is the most appropriate auditor action?
- Ignore as long as system is running
- Raise a finding citing lack of documentation, evaluate impact on product quality, and request corrective action
- Ask the maintenance person to fix it later
- Approve repair verbally
Correct Answer: Raise a finding citing lack of documentation, evaluate impact on product quality, and request corrective action
Q12. Which piece of evidence demonstrates that engineering training is effective for personnel performing GMP-related maintenance?
- Generic online safety course completion unrelated to GMP systems
- Training records showing role-specific competency checks, SOP assessments, and periodic refreshers
- Attendance list for a company picnic
- Employment contracts with job titles only
Correct Answer: Training records showing role-specific competency checks, SOP assessments, and periodic refreshers
Q13. What is the key consideration when auditing cleaning and cleanliness controls for engineering workshops that service sterile areas?
- Workshop proximity to cafeteria
- Segregation of dirty and clean tools, documented cleaning procedures, and validated cleaning methods
- Workshop color scheme
- Number of toolboxes available
Correct Answer: Segregation of dirty and clean tools, documented cleaning procedures, and validated cleaning methods
Q14. Which audit evidence indicates effective management of change (MOC) for equipment modifications?
- MOC forms completed after implementation with no validation
- Completed MOC with risk assessment, updated drawings, revised SOPs, and requalification where applicable before implementation
- Oral approvals from a supervisor
- Supplier recommendations without internal review
Correct Answer: Completed MOC with risk assessment, updated drawings, revised SOPs, and requalification where applicable before implementation
Q15. In relation to energy and utility audits, which control is important to ensure consistent process performance?
- Random power outages to test resilience
- Uninterruptible power supply (UPS), backup generators, and documented restoration procedures for critical utilities
- Dependence on a single utility vendor contract
- Monthly invoices for energy consumption
Correct Answer: Uninterruptible power supply (UPS), backup generators, and documented restoration procedures for critical utilities
Q16. Which risk-based approach should auditors expect to see in engineering department programs?
- Equal effort applied to all systems regardless of criticality
- Prioritization of maintenance, calibration, and validation activities based on system criticality and impact on product quality
- Delegation of all risk assessments to the vendor
- Only cosmetic risks are documented
Correct Answer: Prioritization of maintenance, calibration, and validation activities based on system criticality and impact on product quality
Q17. What is the correct auditor response when finding expired calibration labels on a cascade control device used in aseptic processing?
- Assume device is still accurate and document nothing
- Record a critical finding, quarantine affected batches if applicable, and require immediate calibration and investigation
- Replace the label only
- Ask production to adjust setpoints manually
Correct Answer: Record a critical finding, quarantine affected batches if applicable, and require immediate calibration and investigation
Q18. Which documentation should be reviewed to verify that shutdown and start-up activities are controlled to prevent contamination risks?
