Practice: Sanitary Environment, Zoonotic Disease, and Hazardous Materials

Which disinfectant is most effective against parvovirus in a kennel?

• Chlorhexidine solution

• Diluted household bleach

• Isopropyl alcohol wipes

• Quaternary ammonium spray

Answer explanation

Diluted bleach inactivates non-enveloped viruses like parvovirus. Quaternary ammonium and chlorhexidine do not reliably destroy parvovirus.

Sanitizing differs from sterilizing because sanitizing

• Destroys every living organism present

• Reduces microbes to safe levels

• Removes only visible surface debris

• Uses plain water without chemicals

Answer explanation

Sanitizing lowers microbial counts to safe levels; sterilizing destroys all life. Cleaning alone only removes visible soil without reducing pathogens.

A worker bitten by a stray cat should first

• Apply antibiotic ointment

• Wash the wound thoroughly

• Bandage and resume work

• Wait to see swelling

Answer explanation

Immediate washing reduces rabies and bacterial exposure. Bandaging without cleaning first traps pathogens inside the wound.

Which task most requires wearing a face shield?

• Filing patient records indoors

• Walking dogs on a leash

• Restocking dry kibble bins

• Power-spraying soiled kennel runs

Answer explanation

Power spraying aerosolizes contaminated water, threatening eyes and mucous membranes. Kibble restocking and paperwork pose no splash or aerosol risk.

Salmonella is most often transmitted to workers through

• Bites from infected fleas

• Airborne respiratory droplets

• Contact with reptile feces

• Inhalation of fungal spores

Answer explanation

Salmonella commonly spreads via fecal-oral contact, especially from reptiles. It is not airborne or vector-borne.

Soiled bedding from an isolation cage should be

• Stored until end-of-week pickup

• Aired outside before reuse

• Washed with regular kennel laundry

• Bagged separately and labeled biohazard

Answer explanation

Isolation laundry must be segregated and labeled to prevent cross-contamination. Mixing it with general loads spreads pathogens to healthy animals.

After mopping a treatment room, contact time means the floor must

• Dry within sixty seconds

• Be buffed before it dries

• Be rinsed off right away

• Stay wet for the labeled time

Answer explanation

Disinfectants require the labeled wet contact time to kill pathogens effectively. Rinsing or drying the surface early cuts efficacy short.

Which statement best describes standard precautions?

• Treat every animal as potentially infectious

• Wash hands only after animal bites

• Wear PPE only during surgical procedures

• Use gloves only with visibly sick patients

Answer explanation

Standard precautions assume any animal could carry pathogens regardless of appearance. Selective PPE use leaves gaps that allow zoonotic transmission.

A bottle of cleaner is missing its original label. The worker should

• Pour it into a labeled jug

• Discard it as hazardous waste

• Smell it to identify contents

• Use it only for outside areas

Answer explanation

Unlabeled chemicals cannot be safely identified or matched to safety data. Smelling or guessing the contents risks serious chemical exposure.
