CVA Facility Sanitation and Safety 5 — Questions and Answers
Question 1: When using a quaternary ammonium compound (quat) disinfectant in a veterinary facility, which condition most reduces its effectiveness?
- High ambient temperature
- Presence of organic matter such as feces or blood (Correct answer)
- Low humidity in the room
- Exposure to ultraviolet light
Correct answer: Presence of organic matter such as feces or blood
Organic matter such as feces, blood, or pus significantly neutralizes quaternary ammonium compounds, requiring thorough pre-cleaning before disinfection.
Question 2: A cat recovering from an upper respiratory infection is housed in the same ward as surgical patients. What is the MOST appropriate action?
- Place a sign on the cage door as a warning
- Move the infected cat to an isolation ward immediately (Correct answer)
- Increase ventilation in the room
- Double the disinfection frequency of shared surfaces
Correct answer: Move the infected cat to an isolation ward immediately
Infectious patients must be housed in a designated isolation area to prevent pathogen spread to immunocompromised surgical patients.
Question 3: Which federal agency sets occupational exposure limits (OELs) for hazardous chemicals used in veterinary facilities, such as formaldehyde?
- EPA
- FDA
- OSHA (Correct answer)
- USDA
Correct answer: OSHA
OSHA (Occupational Safety and Health Administration) establishes permissible exposure limits (PELs) for hazardous workplace chemicals including formaldehyde.
Question 4: A veterinary assistant notices the eyewash station has not been flushed this week. What is the correct action?
- Log the finding and notify the next shift
- Flush the eyewash station immediately for at least 5 minutes to clear stagnant water (Correct answer)
- Wait until it is needed before flushing
- Replace the entire eyewash unit as it is contaminated
Correct answer: Flush the eyewash station immediately for at least 5 minutes to clear stagnant water
Eyewash stations should be flushed weekly for at least 5 minutes to prevent microbial growth in stagnant water and ensure readiness in an emergency.
Question 5: What is the primary purpose of a safety data sheet (SDS) in a veterinary clinic?
- To track inventory levels of chemicals
- To provide hazard, handling, first aid, and disposal information for chemical products (Correct answer)
- To certify that a product is approved for veterinary use
- To document employee training on chemical use
Correct answer: To provide hazard, handling, first aid, and disposal information for chemical products
An SDS provides comprehensive information on a chemical's hazards, safe handling procedures, first aid measures, and proper disposal requirements.
Question 6: After cleaning a kennel run that housed a dog with suspected parvovirus, which disinfectant is MOST appropriate?
- Quaternary ammonium compound
- Chlorhexidine solution
- Diluted bleach (sodium hypochlorite) (Correct answer)
- Isopropyl alcohol spray
Correct answer: Diluted bleach (sodium hypochlorite)
Sodium hypochlorite (bleach) at appropriate dilution is one of the few disinfectants effective against parvovirus, a non-enveloped virus resistant to many common disinfectants.
Question 7: Which practice BEST reduces the risk of zoonotic disease transmission when handling animals with unknown health status?
- Wearing gloves only when the animal appears sick
- Using standard precautions including gloves, hand hygiene, and appropriate PPE for every patient (Correct answer)
- Relying on vaccination history to determine precaution level
- Limiting direct contact to less than one minute per animal
Correct answer: Using standard precautions including gloves, hand hygiene, and appropriate PPE for every patient
Standard precautions applied universally to every patient—regardless of known diagnosis—are the most reliable strategy for preventing zoonotic disease transmission.
