6. Global Health and Social Determinants of Health
1. A public health nurse is analyzing a sudden increase in gastrointestinal illness within a rural
community. Data indicates all affected individuals attended a common local festival. Which
epidemiological study design is most appropriate to rapidly identify the specific vehicle of
transmission?
A. Randomized controlled trial
B. Retrospective case-control study
C. Prospective cohort study
D. Cross-sectional descriptive study
CORRECT ANSWER : B
, Rationale: A retrospective case-control study is the most efficient design for investigating
outbreaks, allowing the nurse to compare exposure history between those who fell ill and a
control group. Randomized trials are unethical for investigating outbreaks, prospective cohorts
are too time-consuming, and cross-sectional studies provide only a snapshot without establishing
temporal causality.
2. A community nurse is tasked with developing a disaster response plan for a municipality with a
high percentage of non-English speaking residents. Which strategy is most essential for effective
communication during an acute evacuation?
A. Utilizing standard English-only signage
B. Relying on digital social media alerts
C. Establishing multilingual community liaison networks
D. Distributing comprehensive written manuals post-disaster
CORRECT ANSWER : C
Rationale: Establishing multilingual liaison networks ensures immediate, trusted communication
tailored to the community's linguistic needs, which is vital during an acute crisis. English-only
signage and post-disaster manuals fail to address the immediate emergency communication
barrier, and digital alerts may not be accessible or trusted by all demographics.
3. A nurse is evaluating the health outcomes of a community-based intervention aimed at reducing
pediatric asthma exacerbations. Which indicator best reflects the success of the intervention at
the tertiary prevention level?
A. Number of new asthma diagnoses in the school system
B. Reduction in emergency department visits for asthma
C. Implementation of indoor air quality workshops
D. Screening rates for allergic triggers in the classroom
CORRECT ANSWER : B
Rationale: Tertiary prevention focuses on managing existing conditions to prevent complications
or worsening health status, making a reduction in acute care utilization a primary outcome. New
diagnoses (primary) and workshops/screenings (secondary) do not accurately reflect the
effectiveness of managing established disease.
,4. A nurse is conducting a community assessment using the "Windshield Survey" method. Which
observation provides the most relevant data regarding the social determinants of health in an
urban neighborhood?
A. The number of historical monuments present
B. The accessibility and quality of grocery stores
C. The frequency of public transit schedule updates
D. The aesthetic architectural design of residential buildings
CORRECT ANSWER : B
Rationale: Access to affordable, nutritious food (food deserts) is a critical social determinant of
health that directly impacts community morbidity. While monuments and architecture contribute
to neighborhood character, they have negligible impact on the immediate health outcomes
compared to nutritional access.
5. When applying the Health Belief Model to a community smoking cessation program, which
action most directly addresses the concept of "Perceived Barriers"?
A. Discussing the long-term mortality risks of tobacco use
B. Providing testimonials from former long-term smokers
C. Offering free nicotine replacement therapy and transportation to clinics
D. Displaying posters showing the physiological effects of lung damage
CORRECT ANSWER : C
Rationale: Perceived barriers are the tangible and psychological costs that prevent individuals
from taking action; reducing these costs through free resources and access is a direct
intervention. Mortality risks and physiological imagery address susceptibility and severity, while
testimonials target self-efficacy.
6. A public health nurse is investigating a cluster of lead poisoning cases in a low-income housing
complex. Which intervention represents the highest level of hierarchy of controls for
environmental health?
A. Providing blood lead level testing for all children
B. Educating parents on cleaning dust to reduce ingestion
C. Removing and replacing lead-based paint and piping
, D. Installing air filtration systems in all residential units
CORRECT ANSWER : C
Rationale: Elimination and substitution (removing the lead) are the most effective levels of the
hierarchy of controls. Testing, education, and filtration are administrative or engineering
controls that are less effective than the total removal of the hazard.
7. A nurse is planning a community health program based on the Transtheoretical Model. A cohort
of participants is currently identifying barriers to change but has not yet set a specific start date
for the intervention. Which stage are they in?
A. Precontemplation
B. Contemplation
C. Preparation
D. Action
CORRECT ANSWER : B
Rationale: The contemplation stage is characterized by the acknowledgment of a problem and
the consideration of change, often accompanied by weighing the pros and cons.
Precontemplation involves no intent to change, preparation involves specific planning for action,
and action is the actual implementation of change.
8. Which demographic factor is most strongly associated with health disparities in rural populations
when compared to urban populations?
A. Higher prevalence of genetic disorders
B. Limited access to specialized healthcare services
C. Lower rates of chronic disease burden
D. Greater reliance on preventive dental care
CORRECT ANSWER : B
Rationale: Geographic isolation and the scarcity of healthcare infrastructure (specialists,
hospitals) are the primary drivers of health disparities in rural areas. Genetic disorders are not
disproportionately higher, and rural populations typically face higher chronic disease burdens
with less access to preventive services.
