Correct Answer: Incineration or licensed rendering service

Q8. Which record is essential to trace animal use, procedures, and welfare assessments for regulatory inspections?

• Animal identification and procedure log
• Staff lunch schedules
• Facility landscaping invoices
• Personal journals of technicians

Correct Answer: Animal identification and procedure log

Q9. For maintaining pathogen-free status in a barrier facility, which practice is least compatible?

• Use of HEPA-filtered supply and exhaust air
• Strict gowning and entry protocols
• Regular microbiological sentinel monitoring
• Frequent uncontrolled visitor access

Correct Answer: Frequent uncontrolled visitor access

Q10. What is the primary goal of environmental enrichment in laboratory animal housing?

• To complicate husbandry routines
• To improve animal welfare and promote natural behaviors
• To increase experimental variability intentionally
• To reduce food consumption for cost savings

Correct Answer: To improve animal welfare and promote natural behaviors

Q11. Which chemical disinfectant is commonly recommended for routine decontamination in animal rooms and effective against a broad range of pathogens?

• Sterile water
• 70% ethanol or appropriate quaternary ammonium compounds
• Unscented soap only
• Vegetable oil

Correct Answer: 70% ethanol or appropriate quaternary ammonium compounds

Q12. During an outbreak investigation of murine pathogen, what is the most informative immediate action?

• Ignore and continue routine activities
• Initiate immediate quarantine and perform diagnostic testing
• Release animals to other facilities
• Change all feed suppliers without testing

Correct Answer: Initiate immediate quarantine and perform diagnostic testing

Q13. What is the role of an Institutional Animal Care and Use Committee (IACUC) in an animal research facility?

• Approve study budgets only
• Provide ethical review, protocol approval and oversee welfare compliance
• Manage cafeteria services for staff
• Operate animal transport vehicles

Correct Answer: Provide ethical review, protocol approval and oversee welfare compliance

Q14. Which parameter is most important to control in breeding rooms to maximize reproductive performance of rodents?

• Music volume in the room
• Consistent photoperiod, temperature, and humidity
• Frequency of door openings without concern
• Decorative wall color

Correct Answer: Consistent photoperiod, temperature, and humidity

Q15. What is the correct sequence for personal protective equipment (PPE) removal to minimize contamination when exiting an animal room?

• Remove shoes, then gloves, then gown
• Remove gown, then gloves, then mask/eye protection
• Remove mask first, then gloves, then gown
• Shake off PPE before removing anything

Correct Answer: Remove gown, then gloves, then mask/eye protection

Q16. Which monitoring strategy provides early detection of subclinical infections in a rodent colony?

• Visual inspection only
• Sentinel animals exposed to soiled bedding and periodic serology/PCR
• Waiting for overt clinical signs in breeders
• Annual equipment inventory checks

Correct Answer: Sentinel animals exposed to soiled bedding and periodic serology/PCR

Q17. For water quality in an animal facility, which parameter must be routinely controlled to prevent health issues?

• Presence of essential vitamins
• Bacterial contamination levels and chemical contaminants
• Water color matching cage bedding
• Water sourced only from distilled vendors without testing

Correct Answer: Bacterial contamination levels and chemical contaminants

Q18. What is the most appropriate method to validate a facility cleaning SOP?

• Rely only on staff verbal confirmation
• Quantify residual bioburden using ATP or microbiological swabbing after cleaning
• Assume cleaning is effective if surfaces look clean
• Change cleaning products frequently without testing

Correct Answer: Quantify residual bioburden using ATP or microbiological swabbing after cleaning
