ACTUAL EXAM | PRACTICE QUESTIONS AND
ANSWERS | EXAM REVIEW | 100% CORRECT
ANSWERS | VERIFIED SOLUTIONS
This comprehensive practice examination is designed as the ultimate capstone
review for nursing candidates completing advanced study in community, public,
and population health nursing. Spanning 100 meticulously crafted items, it
integrates all major content domains: epidemiological principles and biostatistics,
community assessment frameworks, program planning and evaluation, health
policy and law, environmental and occupational health, cultural competence,
disaster preparedness, and ethical-legal reasoning. Questions are structured at the
high critical-thinking level expected of board certification and graduate-level
examinations, requiring synthesis, analysis, and application to complex, real-world
scenarios. The correct answers are accompanied by detailed rationales, explaining
why each option is optimal and why alternatives fail. This document is an ideal
tool for final examination preparation, self-assessment, and remediation. By
systematically working through these items, candidates will refine their ability to
think like a public health nurse, lead interprofessional teams, advocate for health
equity, and make evidence-based decisions that protect and improve population
health outcomes across diverse settings.

1. A public health nurse is analyzing mortality data using years of potential life
lost (YPLL). A death at age 25 contributes how many YPLL if the standard life
expectancy is 75 years?
A) 25
B) 50
C) 75
D) 100
Correct Answer: B
YPLL = standard age – age at death = 75 – 25 = 50. This measure weights
premature mortality heavily, highlighting conditions that kill younger populations.
2. In a case-control study of ovarian cancer, 60 of 100 cases reported talc use,
while 30 of 100 controls reported talc use. What is the odds ratio?
A) 2.0
B) 3.5
C) 4.0
D) 1.5
Correct Answer: B
Odds ratio = (a/c) / (b/d) = (60/40) / (30/70) = 1..4286 = 3.5. It indicates that
cases had 3.5 times the odds of talc exposure compared to controls.
3. A screening test has sensitivity 99% and specificity 95%. If the prevalence of
the disease is 0.5%, what is the approximate positive predictive value
(PPV)?
A) 99%
B) 50%
, C) 9%
D) 95%
Correct Answer: C
With very low prevalence, PPV drops sharply. Using Bayes: PPV = (0.99 × 0.005) /
[0.99 × 0.005 + 0.05 × 0.995] = 0.00495 / (0.00495 + 0.04975) ≈ 0.00495/0.0547 ≈
9%. Option A and D are test characteristics; B is mid-range not correct.
4. Which epidemiological measure is best suited for describing the burden of
chronic disease in a population at a single point in time?
A) Incidence density
B) Cumulative incidence
C) Point prevalence
D) Attack rate
Correct Answer: C
Point prevalence captures the proportion of the population with the disease at a
specific moment, reflecting burden. Incidence measures new cases over time.
5. A nurse uses the Community-as-Partner model. The community’s “core”
includes all of the following EXCEPT:
A) Demographics
B) Values and beliefs
C) History
D) Fire department response time
Correct Answer: D
The core comprises the community’s demographics, history, values, and beliefs.
Fire response time is part of the safety subsystem, one of the eight subsystems
surrounding the core.
6. A nurse is analyzing an epidemic curve showing intermittent peaks spaced
approximately one incubation period apart. This pattern indicates:
A) Point-source outbreak
B) Continuous common-source outbreak
, C) Propagated outbreak
D) Seasonal endemic curve
Correct Answer: C
Propagated outbreaks spread person-to-person, with successive waves separated
by the incubation period. Point-source shows a single peak; continuous common-
source may show a plateau.
7. The nurse calculates a relative risk of 0.75 (95% CI 0.60–0.93) for a dietary
intervention and hypertension. This finding means:
A) The intervention has no effect
B) The intervention reduces risk by 25%, and the result is statistically
significant
C) The intervention increases risk by 75%
D) The result is not significant because the CI crosses 1.0
Correct Answer: B
RR <1 indicates protective effect; 0.75 = 25% risk reduction. The CI does not include
1, so it is significant. Option D misinterprets the CI.
8. A community health nurse is assessing the built environment for walkability.
Which feature is associated with increased physical activity?
A) High-density, single-use zoning separating residential and commercial
areas
B) Cul-de-sac street designs with limited connectivity
C) Mixed land use with high street connectivity and sidewalks
D) Wide, high-speed arterial roads without crosswalks
Correct Answer: C
Mixed use and connected streets facilitate walking and biking. Single-use zoning
and cul-de-sacs increase car dependency.
9. During a community meeting to prioritize health issues, the nurse facilitates
a multivoting process after brainstorming. This approach is most consistent
with which public health competency?
A) Financial management
