Question 1

A veterinarian is bitten by a bat during a wildlife rescue. The bat escapes before capture. What is the appropriate public health response?

Accepted Answer

The veterinarian should begin rabies PEP immediately since the bat cannot be tested

Answer

When the offending bat cannot be tested, rabies PEP should begin immediately because bats are a leading source of human rabies in the US and the risk is unacceptably high.

Question 2

Which antimicrobial resistance concern is directly linked to veterinary use of antibiotics and has significant public health implications?

Accepted Answer

Selection for resistant Salmonella, Campylobacter, and E. coli strains that can transfer resistance genes to human pathogens

Answer

Agricultural antibiotic use selects for resistant zoonotic pathogens and promotes horizontal gene transfer of resistance elements that can ultimately affect human medicine.

Question 3

Avian influenza H5N1 surveillance requires veterinarians to report suspected cases promptly. Which clinical presentation in domestic poultry should trigger immediate reporting?

Accepted Answer

Sudden high mortality (>50%) with neurological signs, hemorrhages, and respiratory distress in a flock

Answer

Highly pathogenic avian influenza (HPAI) characteristically causes sudden, severe mortality with neurological signs and hemorrhagic lesions, warranting immediate regulatory reporting.

Question 4

Which regulatory framework governs the importation of animals and animal products into the US to prevent the introduction of foreign zoonotic diseases?

Accepted Answer

USDA APHIS regulations in coordination with CDC quarantine authority at ports of entry

Answer

USDA APHIS regulates live animal and animal product imports for agricultural disease prevention, while CDC has authority to quarantine animals posing public health risks, requiring coordinated jurisdiction.

Question 5

Occupational exposure to Brucella in veterinary settings is best prevented by which combination of measures when assisting with bovine abortions?

Accepted Answer

Gloves, eye protection, N95 respirator, and immediate handwashing with disinfectant soap

Answer

Brucella can penetrate intact mucous membranes and skin through aerosols and direct contact with infected fetal tissues, requiring barrier PPE and proper decontamination.
