Introduction
This comprehensive examination assesses the candidate's mastery of veterinary preventive medicine
across the American College of Veterinary Preventive Medicine (ACVPM) specialty domains. It evaluates
competency in epidemiology, biostatistics, zoonotic disease control, food safety, regulatory medicine,
environmental health, public health administration, and emergency preparedness. Questions emphasize
real-world application, critical decision-making, and evidence-based practice. Multiple-choice and
scenario-based items require integration of foundational theory with applied professional knowledge.
Successful performance demonstrates readiness for board certification and autonomous practice in
veterinary preventive medicine.
Section One: Questions 1–250
Domain A: Veterinary Epidemiology and Biostatistics (Questions 1–55)
1. A cross-sectional study of dairy herds finds that herds using bulk tank milk filters have lower
prevalence of mastitis. The measure of association most appropriate for this study design is:
A. Relative risk
B. Odds ratio
C. Prevalence ratio
D. Incidence rate ratio
🟢 C. Prevalence ratio
🔴 RATIONALE: In cross-sectional studies examining prevalence, the prevalence ratio (ratio of
prevalences between exposed and unexposed groups) is the most appropriate measure of association,
as incidence measures cannot be determined when disease timing is unknown.
2. An outbreak of salmonellosis in a veterinary teaching hospital affects 15 of 120 hospitalized dogs
over 3 weeks. The attack rate is:
,A. 8.3%
B. 12.5%
C. 15.0%
D. 20.0%
🟢 B. 12.5%
🔴 RATIONALE: Attack rate equals the number of new cases divided by the population at risk,
expressed as a percentage: 15 cases / 120 dogs × 100 = 12.5%.
3. A zoonotic disease investigation identifies that 80% of human cases had contact with raw milk.
The epidemiological measure describing this proportion is:
A. Attributable risk
B. Attributable fraction among exposed
C. Population attributable risk
D. Relative risk
🟢 B. Attributable fraction among exposed
🔴 RATIONALE: The attributable fraction among exposed represents the proportion of disease among
exposed individuals that is attributable to the exposure, calculated as (Risk_exposed - Risk_unexposed)
/ Risk_exposed.
4. A case-control study of leptospirosis in dogs finds an odds ratio of 4.5 for dogs with access to
standing water. The correct interpretation is:
A. Dogs with standing water access have 4.5 times higher risk of leptospirosis
B. The odds of leptospirosis are 4.5 times higher in exposed dogs compared to unexposed
C. 4.5% of leptospirosis cases are attributable to standing water
D. There is no association between standing water and leptospirosis
🟢 B. The odds of leptospirosis are 4.5 times higher in exposed dogs compared to unexposed
🔴 RATIONALE: In a case-control study, the odds ratio estimates the odds of exposure in cases
compared to controls. An OR of 4.5 means the odds of leptospirosis are 4.5 times higher in dogs with
standing water access.
5. The epidemiological triad (epidemiological triangle) of how diseases are caused and spread
includes:
A. Time, place, person
B. Agent, host, environment
C. Source, transmission, susceptibility
D. Infectivity, pathogenicity, severity
🟢 B. Agent, host, environment
🔴 RATIONALE: The epidemiological triad consists of the agent, host, and environment, which interact
to cause disease.
,6. When a disease occurs frequently or is constantly present in a population, the disease is
considered:
A. Pandemic
B. Endemic
C. Epidemic
D. Chronic
🟢 B. Endemic
🔴 RATIONALE: Endemic refers to the constant presence and/or usual prevalence of a disease or
infectious agent in a population within a geographic area.
7. The disease that occurs in greater than normal expectation is known as:
A. Epidemic
B. Endemic
C. Pandemic
D. Epizootic
🟢 A. Epidemic
🔴 RATIONALE: An epidemic refers to an increase, often sudden, in the number of cases of a disease
above what is normally expected in that population in that area.
8. An exotic disease is a disease that:
A. Affects only wild animals
B. Is introduced into a new area previously free from it
C. Has no known treatment
D. Spreads rapidly within a population
🟢 B. Is introduced into a new area previously free from it
🔴 RATIONALE: An exotic disease is one that is introduced into a new geographic area where it was
previously absent.
9. The measure of association used in a cohort study is:
A. Odds ratio
B. Prevalence ratio
C. Relative risk
D. Correlation coefficient
🟢 C. Relative risk
🔴 RATIONALE: Cohort studies calculate relative risk (risk ratio), which compares the incidence of
disease in exposed versus unexposed groups.
10. A study finds that the sensitivity of a diagnostic test is 95% and specificity is 90%. This means:
, A. 95% of diseased animals test positive; 90% of non-diseased test negative
B. 95% of non-diseased test negative; 90% of diseased test positive
C. 95% of positive tests are true positives; 90% of negative tests are true negatives
D. 95% of animals have the disease; 90% do not
🟢 A. 95% of diseased animals test positive; 90% of non-diseased test negative
🔴 RATIONALE: Sensitivity is the proportion of truly diseased animals that test positive. Specificity is
the proportion of truly non-diseased animals that test negative.
11. The positive predictive value of a diagnostic test depends on:
A. Sensitivity only
B. Specificity only
C. Prevalence of disease in the population
D. Sample size only
🟢 C. Prevalence of disease in the population
🔴 RATIONALE: Positive predictive value is influenced by disease prevalence: as prevalence increases,
PPV increases; as prevalence decreases, PPV decreases.
12. Which study design is most appropriate for studying rare diseases?
A. Cohort study
B. Cross-sectional study
C. Case-control study
D. Randomized controlled trial
🟢 C. Case-control study
🔴 RATIONALE: Case-control studies are efficient for rare diseases because they begin with cases and
select controls, requiring fewer subjects than cohort studies.
13. A randomized controlled trial is the gold standard for establishing:
A. Prevalence
B. Causality
C. Incidence
D. Correlation
🟢 B. Causality
🔴 RATIONALE: Randomization minimizes confounding and allows causal inference, making RCTs the
gold standard for establishing cause-effect relationships.
14. Which measure describes the proportion of a population that has a disease at a specific point in
time?
