Sample AOBPM Preventive Medicine Practice Questions

Try these sample questions to test your AOBPM Preventive Medicine exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which study design provides the strongest evidence for causation when investigating a new drug's efficacy?
A.Case report
B.Cross-sectional study
C.Randomized controlled trial (RCT)
D.Ecological study
Explanation: RCTs provide the highest internal validity for assessing efficacy by randomization minimizing confounding. The hierarchy of evidence: systematic review of RCTs > individual RCT > cohort > case-control > cross-sectional > case series > expert opinion.
2A USPSTF Grade A recommendation means:
A.There is at least moderate certainty that the net benefit is small
B.The USPSTF recommends the service; there is high certainty that the net benefit is substantial
C.The USPSTF recommends against the service
D.Current evidence is insufficient to assess benefits and harms
Explanation: USPSTF Grade A = recommend the service with high certainty of substantial net benefit. Grade B = recommend, moderate certainty of moderate-substantial benefit. Grade C = selective recommendation (small net benefit). Grade D = recommend against. Grade I = insufficient evidence.
3Which respirator type is required for OSHA-mandated protection against airborne tuberculosis exposure?
A.Surgical mask
B.N95 filtering facepiece respirator (or higher protection level), fit-tested
C.Cloth mask
D.Half-face respirator with chemical cartridge
Explanation: OSHA requires fit-tested N95 (or higher protection — PAPR, full-face N100) for healthcare workers exposed to TB. Annual fit-testing, medical evaluation, and training are mandated. Surgical masks do not provide respiratory protection.
4An adult with persistent lead exposure has a blood lead level of 30 mcg/dL. According to current CDC/OSHA guidance, the most appropriate action is:
A.No action needed
B.Counsel on exposure reduction, evaluate source, consider chelation only if symptomatic or BLL >=80 mcg/dL; OSHA medical removal at BLL >=60 mcg/dL (or two consecutive >=50)
C.Immediate hospitalization
D.Permanent disability
Explanation: Adult lead: counsel and identify source; chelation reserved for symptomatic or BLL >=80 mcg/dL (or earlier if encephalopathy). OSHA medical removal triggers at BLL >=60 mcg/dL or two consecutive >=50; return at <40 mcg/dL. Pediatric reference is much lower (CDC 3.5 mcg/dL action level 2021).
5Which intervention is recommended by USPSTF (Grade B) for the prevention of cardiovascular disease in adults aged 40-75 with at least one risk factor?
A.Vitamin D supplementation
B.Use of statins for primary prevention if 10-year ASCVD risk >=10% (Grade B); selective offering at 7.5-10% (Grade C)
C.Daily aspirin for all adults
D.No prevention recommended
Explanation: USPSTF 2022: statin primary prevention in adults 40-75 with >=1 CVD risk factor and >=10% 10-year ASCVD risk is Grade B. 7.5-9.9% risk = Grade C (selective). >=76 years = insufficient. 2022 USPSTF removed routine aspirin primary prevention >=60.
6Which is the typical 'time of useful consciousness' at an altitude of 25,000 feet?
A.1 minute
B.3-5 minutes
C.30 seconds
D.15 minutes
Explanation: TUC values: 18,000 ft 20-30 min; 22,000 ft 10 min; 25,000 ft 3-5 min; 28,000 ft 2.5-3 min; 30,000 ft 1-2 min; 35,000 ft 30-60 sec; 40,000 ft 15-20 sec; 43,000 ft 9-12 sec; 50,000 ft 6-9 sec.
7Which is the appropriate decompression sickness treatment per US Navy diving tables?
A.100% oxygen on the surface only
B.100% oxygen and hyperbaric oxygen therapy (recompression chamber treatment) per US Navy Treatment Table 5 or 6 (most commonly TT6 for serious DCS)
C.Rapid ascent to altitude
D.Aspirin
Explanation: DCS treatment: 100% O2 at the surface immediately while transporting to hyperbaric chamber. Recompression per US Navy Treatment Table 5 (mild type I, ~135 min) or Table 6 (Type II/serious, ~4.75 hr). Goal: shrink nitrogen bubbles, redissolve, prevent permanent injury.
8An epidemiology study finds odds ratio of 3.0 (95% CI 1.5-6.0) for smoking and a rare lung disease. Which is the correct interpretation?
A.Smokers have 3x the odds of the disease, statistically significant (CI excludes 1.0)
B.Smokers have 3x the risk
C.Non-smokers have 3x the odds
D.No association exists
Explanation: OR = 3.0 means smokers have 3x the odds of disease. CI 1.5-6.0 excludes 1.0 (the null), so statistically significant. For rare diseases (~prevalence <10%), OR approximates RR.
9Which is the calculation for sensitivity in a 2x2 diagnostic test table?
A.TP / (TP + FN)
B.TN / (TN + FP)
C.TP / (TP + FP)
D.TN / (TN + FN)
Explanation: Sensitivity = TP / (TP + FN) — proportion of diseased individuals correctly identified as positive. Specificity = TN / (TN + FP). PPV = TP / (TP + FP). NPV = TN / (TN + FN).
10The Bradford Hill criteria for causation include all of the following EXCEPT:
A.Strength of association
B.Biological plausibility
C.Statistical significance alone
D.Temporality
Explanation: Bradford Hill criteria: strength, consistency, specificity, temporality, biological gradient (dose-response), plausibility, coherence, experiment, analogy. Statistical significance is necessary but not sufficient — Hill explicitly cautioned against relying on p-values alone.

AOBPM Preventive Medicine Study Tips from Top Performers

1Master USPSTF Grade A and B recommendations cold — they appear repeatedly. Cancer screening: cervical (21-65, Pap q3y 21-29, cotest q5y 30-65), breast (40-74 biennial 2024 update), colorectal (45-75: FIT annual, sDNA 1-3y, colonoscopy 10y, sigmoidoscopy 5y + FIT, CT colonography 5y), lung (50-80 with 20 pack-year history, quit <15y), AAA (one-time men 65-75 ever-smoker). CVD prevention: statin 40-75 with >=1 risk factor + >=10% ASCVD risk (Grade B); BP screening adults; tobacco cessation counseling all (Grade A).
2Internalize occupational toxicology thresholds: OSHA PEL for lead (50 mcg/m^3 air; medical removal at BLL >=60), silica respirable PEL 50 mcg/m^3, asbestos PEL 0.1 f/cc, benzene 1 ppm, formaldehyde 0.75 ppm. Adult BLL action: >5 mcg/dL chelate consideration; pediatric: CDC reference 3.5 mcg/dL (2021). Mercury (elemental vapor neuro; methylmercury fish/Minamata), arsenic (skin/lung/bladder cancer), cadmium (renal/lung). Audiometric standard threshold shift = 10 dB average shift in 2/3/4 kHz from baseline.
3Drill epidemiology calculations: incidence = new cases/population at risk/time; prevalence = total cases / population. Cohort produces RR = exposed risk / unexposed risk. Case-control produces OR = (a*d)/(b*c). Attributable risk AR = R_exposed - R_unexposed; AR% = (AR/R_exposed)*100. Number needed to treat = 1/ARR. Sensitivity rules out (SnNout), specificity rules in (SpPin). LR+ >10 strong rule-in; LR- <0.1 strong rule-out. PPV depends on prevalence; in low-prevalence settings even high-specificity tests have low PPV.
4For aerospace medicine know the hypoxia ladder: indifferent stage <10,000 ft, compensatory 10,000-15,000 ft, disturbance 15,000-20,000 ft (visual, cognitive, motor impairment), critical >20,000 ft. Time of useful consciousness at 25,000 ft is ~3-5 minutes, at 35,000 ft ~30-60 seconds, at 40,000 ft ~15-20 seconds. Decompression sickness Type I (joint bends, skin), Type II (neurologic, chokes, staggers) treated with 100% O2 and hyperbaric recompression (Table 5/6). FAA medical: Class I (ATP) 12 months age <40 / 6 months >=40, Class II (commercial) 12 months, Class III (private) 60 months <40 / 24 months >=40.
5Master ACIP immunization adult highlights for 2026: annual flu all ages; Td or Tdap every 10 years; HPV through age 26 (shared decision 27-45); zoster (Shingrix 2-dose >=50, or immunocompromised >=19); pneumococcal (PCV15+PPSV23 OR PCV20 single, recommended age >=65 or risk-based 19-64); RSV >=75 universal and 60-74 shared decision; COVID-19 per annual ACIP guidance. Catch-up MMR/varicella as needed. For QI methodology: PDSA cycles (Plan-Do-Study-Act), Lean (eliminate waste — TIMWOOD), Six Sigma DMAIC (Define-Measure-Analyze-Improve-Control), fishbone/Ishikawa, run vs control charts, root cause analysis (5 Whys).

Frequently Asked Questions

Who is eligible for the AOBPM Preventive Medicine exam?

Candidates must be DOs from a COCA-accredited osteopathic college who have completed an internship/transitional year plus at least one year (typically two for Public Health/Community Medicine) of an AOA-approved or ACGME-accredited preventive medicine residency in their chosen track (aerospace, occupational/environmental, or public health/community). A Master of Public Health (MPH) or equivalent covering biostatistics and epidemiology is required. An unrestricted US medical license is also required.

How is the AOBPM exam structured?

Each track combines a 4-hour written exam (100 multiple-choice questions over 2 hours plus 3 essay questions over 2 hours) and a ~45-minute oral examination covering administration, environment, and clinical content at 33% each. All components are scored on a 200-800 scale with a passing score of 500. AOBPM is transitioning the Component 3 OCC written exam to Longitudinal Assessment with continuous quarterly questions for aerospace, occupational/environmental, public health/community medicine, and CAQ occupational medicine.

What is the fee for the AOBPM exam?

The Public Health/Community Medicine track lists ~$800 for the written examination and ~$800 for the oral examination. The CAQ in Occupational Medicine has its own fee. Confirm current per-track fees on the AOBPM exam page. Annual OCC dues apply after certification. Late registration and rescheduling fees may apply.

Which tracks does the AOBPM certify?

AOBPM offers primary certification in three tracks: Aerospace Medicine, Occupational/Environmental Medicine, and Public Health/Community Medicine. A Certificate of Added Qualifications (CAQ) in Occupational Medicine is also offered every October. Candidates select a single primary track based on their residency training and MPH coursework. Cross-track certification requires additional residency training.

How long should I study for the AOBPM boards?

Most preventive medicine residents report 300-500 dedicated hours over 4-8 months. A common split: ~25% epidemiology/biostatistics, ~25% occupational and environmental health, ~15% USPSTF clinical preventive care, ~10% public health systems/policy, ~10% the candidate's primary track (aerospace, occupational, or public health), ~10% research methods/QI, and ~5% OMM in prevention and ethics. USPSTF Grade A/B and ACIP immunization schedules are very high-yield.

What scaled score do I need to pass the AOBPM exam?

Each component (written and oral) is scored on a 200-800 scaled metric with a passing score of 500 or higher required on each. Candidates may retake failed components up to three times within a six-year window per AOBPM policy. Content-area sub-scores are reported for diagnostic feedback but do not affect pass/fail status.

What is the Longitudinal Assessment replacing the AOBPM written?

For Osteopathic Continuous Certification (OCC) Component 3, AOBPM now offers Longitudinal Assessment (LA) in lieu of the traditional written recertification exam. LA delivers quarterly question batches that diplomates complete continuously over the certification cycle, similar to ABMS-board LKA pathways. LA applies to aerospace, occupational/environmental, public health/community medicine, and CAQ occupational medicine. Initial certification still uses the traditional written + oral exam structure.

Is the AOBPM exam offered remotely?

AOBPM has offered the Public Health/Community Medicine written exam remotely (Spring 2026), reflecting a broader move toward remote-proctored testing. Other components and tracks may still require in-person administration. Check the AOBPM all-exams page for the current delivery method, dates, and proctoring requirements for your specific track and component.
