, Question 1
A cohort study reports a risk ratio of 2.5 (95% CI: 1.2-5.0) for the association
between a novel occupational exposure and a chronic disease. Which statement
best interprets this result?
A. The exposure is a statistically significant risk factor, but the wide
confidence interval suggests limited precision.
B. The exposure is protective because the confidence interval includes
values below 1.0.
C. There is no association because the confidence interval is wide.
D. The risk ratio indicates a 2.5% increase in disease risk among exposed
individuals.
Correct Answer: A - The exposure is a statistically significant risk
factor, but the wide confidence interval suggests limited precision.
RATIONALE
A risk ratio of 2.5 with a 95% CI excluding 1.0 indicates a statistically
significant positive association. The wide interval (1.2-5.0) reflects
imprecision, possibly due to small sample size. Option B is incorrect
because the entire interval is above 1.0, indicating increased risk.
Option D misinterprets the ratio as a percentage increase.
Question 2
In a randomized controlled trial, intention-to-treat analysis is preferred over
per-protocol analysis primarily to:
A. Increase statistical power by including all randomized participants.
B. Preserve the benefits of randomization and avoid bias from
non-random dropout.
C. Estimate the true biological effect of treatment among compliant
participants.
D. Reduce the cost and complexity of data collection.
Correct Answer: B - Preserve the benefits of randomization and
Page 2
,avoid bias from non-random dropout.
RATIONALE
Intention-to-treat analysis maintains randomization and minimizes
bias from selective dropout or non-compliance, reflecting real-world
effectiveness. Per-protocol analysis can introduce selection bias and
overestimate efficacy. Option A is not the primary rationale; option C
describes per-protocol, and option D is unrelated.
Question 3
Which of the following best illustrates the concept of 'moral hazard' in health
insurance?
A. An individual avoids preventive care because insurance covers only
catastrophic events.
B. A patient seeks unnecessary expensive tests because they do not bear
the full cost.
C. An insurer denies coverage for a pre-existing condition to reduce costs.
D. A provider prescribes a cheaper generic drug to save the patient
money.
Correct Answer: B - A patient seeks unnecessary expensive tests
because they do not bear the full cost.
RATIONALE
Moral hazard occurs when individuals change their behavior because
they are insulated from the full cost, leading to overutilization. Option
A describes underuse due to coverage gaps, option C is about adverse
selection or underwriting, and option D reflects cost-conscious
prescribing.

, Question 4
A community health assessment finds that a neighborhood has high rates of
asthma and is located near a major highway. Which environmental health
concept best explains this association?
A. Bioaccumulation of persistent organic pollutants.
B. Environmental justice and disproportionate exposure to traffic-related
air pollution.
C. Epidemiological transition due to improved sanitation.
D. Radon gas infiltration from soil.
Correct Answer: B - Environmental justice and disproportionate
exposure to traffic-related air pollution.
RATIONALE
The scenario exemplifies environmental justice, where marginalized
communities face disproportionate environmental hazards like
traffic-related air pollution linked to asthma. Bioaccumulation
involves toxins in the food chain, epidemiological transition refers to
shifts in disease patterns, and radon is unrelated to highway proximity.
Question 5
Which of the following is a key limitation of using crude mortality rates to
compare health status across populations?
A. They do not account for differences in age distribution between
populations.
B. They are not standardized for cause of death.
C. They cannot be calculated for small populations.
D. They require individual-level data that is often unavailable.
Correct Answer: A - They do not account for differences in age
distribution between populations.
