Quiz 1

1.

In research, a veterinarian’s main responsibility is:

A. Treat every animal as an individual patient B. Ensure welfare and compliance with the approved protocol C. Follow the researcher's instructions no matter what D. Only collect data for the experiment

Please select an answer

Tip: Research vets balance animal welfare and protocol adherence. Sometimes the protocol overrides standard clinical priorities.

2.

The 3R's in research stand for:

A. Replacement, Reduction, Refinement B. Reuse, Reduce, Recycle C. Rest, Recover, Respond D. Research, Review, Report

Please select an answer

These guide ethical use of animals. Even if “suffering” occurs in a study, the 3Rs ensure it is justified and minimized.

3.

What is a humane endpoint?

A. A point where suffering is minimized or the animal is removed from the study B. When the study ends, no matter the animal’s condition C. Only when the animal is obviously in pain D. When the animal reaches maturity

Please select an answer

Humane endpoints prevent unnecessary suffering—even if the study’s aim involves pain.

4.

Which housing system best reduces pathogen exposure in rodents?

A. Open-top cages B. Standard farm hutches C. Individually Ventilated Cages (IVCs) D. Aquatic tanks

Please select an answer

Environmental control is critical for both welfare and reliable research data.

5.

What is the purpose of a sentinel program?

A. Provide enrichment to social animals B. Detect hidden pathogens that could compromise the study C. Track animal growth rates D. Train new staff on handling

Please select an answer

Healthy animals can carry subclinical infections—sentinels catch them before they affect results.

6.

In a pain study, analgesia should be:

A. Administered only if mandated by the approved protocol B. Given to all animals no matter the study C. Optional depending on the researcher’s preference D. Ignored entirely to preserve the study outcome

Please select an answer

Tip: Some studies specifically measure pain, so analgesia may be restricted—but this is always ethically reviewed and justified by the AEC.

7.

Which statement about a research veterinarian’s authority is true?

A. They can halt procedures if animal welfare is threatened, even during critical studies B. Their decisions are always overridden by the Principal Investigator C. They only monitor records, not animals directly D. They follow researcher instructions without question

Please select an answer

Tip: Morality is sometimes complex, but vets have ultimate authority to protect welfare within the approved study framework.

8.

Environmental deviations, like high humidity, can:

A. Improve animal comfort B. Introduce scientific variables that compromise results C. Only affect appearance, not physiology D. Are irrelevant if the study continues

Please select an answer

Tip: Welfare and science are intertwined; poor environment can harm both the animal and the data.
