2. Epidemiological Principles and Disease Surveillance
3. Environmental Health and Occupational Safety
4. Health Promotion, Risk Reduction, and Disease Prevention

6. Global Health and Emergency Preparedness
7. Nursing Policy, Advocacy, and Social Determinants of Health
1. A public health nurse is conducting a community assessment in a neighborhood with high rates
of asthma in children. Upon analyzing the data, the nurse identifies that the neighborhood is
adjacent to a major industrial highway and has high levels of particulate matter. Which of the
following interventions represents a secondary prevention strategy for this population?
A. Advocating for local policy changes to restrict heavy truck traffic during school hours.
B. Implementing a school-based screening program to identify children with early
respiratory symptoms.
C. Providing educational workshops on the use of air purifiers and avoiding outdoor exercise
during high-pollution days.
D. Providing comprehensive management and rehabilitation services for children diagnosed with
chronic obstructive airway disease.
CORRECT ANSWER : B
, Rationale: Secondary prevention focuses on early detection and prompt intervention to limit the
impact of a disease. Screening children for respiratory symptoms allows for early identification
and treatment, preventing progression. A is a primary prevention (policy/regulatory), C is
primary prevention (health education), and D is tertiary prevention
(rehabilitation/management).
2. A community health nurse is using the MAPP (Mobilizing for Action through Planning and
Partnerships) model to address local health inequities. The nurse is currently facilitating a
meeting to identify community strengths and the forces of change. Which core function of public
health is the nurse primarily executing?
A. Assurance
B. Assessment
C. Policy Development
D. Primary Prevention
CORRECT ANSWER : B
Rationale: The Assessment core function involves the systematic collection, analysis, and
monitoring of health problems and community needs. MAPP’s process of identifying strengths
and forces of change is a fundamental part of the assessment phase. Assurance and Policy
Development occur later in the cycle, while primary prevention is a level of intervention, not a
core function.
3. An occupational health nurse is evaluating a manufacturing facility where workers are exposed
to high noise levels. The nurse recommends installing sound-dampening panels around the
machinery to reduce noise at the source. According to the hierarchy of controls, which level of
prevention is this intervention?
A. Secondary prevention
B. Personal Protective Equipment (PPE) utilization
C. Primary prevention
D. Tertiary prevention
CORRECT ANSWER : C
Rationale: Engineering controls like sound-dampening panels are considered primary
prevention because they aim to prevent the hazard (noise) from affecting the worker in the first
place, rather than just protecting the individual. PPE is a lower-level control, and
, secondary/tertiary preventions relate to screening or treating existing health issues, which is not
the goal of engineering controls.
4. A nurse working for a refugee health clinic is coordinating care for a family that has recently
arrived in the country. The nurse recognizes that the father is suffering from PTSD and the
children are showing signs of nutritional deficiencies. Which of the following best reflects
"upstream" thinking in this scenario?
A. Referring the children to a nutritionist for a customized meal plan.
B. Coordinating counseling services for the father to manage his trauma symptoms.
C. Collaborating with local housing and food security agencies to stabilize the family’s
socioeconomic environment.
D. Assessing the family for common infectious diseases like tuberculosis or hepatitis.
CORRECT ANSWER : C
Rationale: Upstream thinking focuses on the root causes of health problems, such as social
determinants of health like housing and food security, rather than just treating the resulting
symptoms. Options A, B, and D are "downstream" approaches that focus on individual-level
clinical interventions for existing problems.
5. When applying the "Web of Causation" model to investigate an outbreak of Salmonella linked to
a local community potluck, which factor represents the "agent" in the epidemiological triad?
A. The kitchen facility where the food was prepared.
B. The bacteria (Salmonella) present in the contaminated food.
C. The immunocompromised elderly guests who became ill.
D. The improper temperature regulation during food storage.
CORRECT ANSWER : B
Rationale: In the epidemiological triad, the "agent" is the biological, chemical, or physical
factor that causes the disease. Salmonella is the biological agent. The kitchen (environment) and
the guests (host) are other components, while the temperature is a contributing factor within the
environment.
6. A nurse is evaluating the effectiveness of a community smoking cessation program using the
SMART criteria. Which of the following goals is most effectively written?
, A. Decrease the number of smokers in the neighborhood by a large amount within the next few
years.
B. Reduce the local smoking prevalence rate by 15% among adults aged 18–45 by
December 31, 2027.
C. Teach community members about the dangers of tobacco and encourage them to quit.
D. Improve the overall health of the community by helping people stop smoking.
CORRECT ANSWER : B
Rationale: SMART goals must be Specific, Measurable, Assignable, Realistic, and Time-bound.
Option B includes a specific target percentage, a specific demographic, and a clear deadline.
The other options are vague and lack measurable parameters.
7. A nurse is caring for a patient from a culture that values fatalism regarding chronic illness. The
patient refuses to take daily blood pressure medication, stating that "it is God's will." Which
approach demonstrates the most effective use of cultural humility?
A. Explain that medication is a scientific necessity and non-compliance will lead to a stroke.
B. Ask the patient to describe their beliefs about health and how they think we can honor
those beliefs while managing their blood pressure.
C. Involve the patient’s religious leader to convince them that taking medicine is also God's will.
D. Document the patient’s refusal and discharge them from the clinic for non-compliance.
CORRECT ANSWER : B
Rationale: Cultural humility requires an ongoing process of self-reflection and partnership.
Asking the patient to share their perspective and working together to find a balance respects
their autonomy and cultural beliefs. Option A is condescending, C assumes the leader’s
authority, and D is punitive.
8. An epidemiological study reports a high "specificity" for a new screening tool used to detect
early-stage colorectal cancer. What does this mean for the community health program?
A. The test will accurately identify most people who have the disease.
B. The test will correctly identify most people who do not have the disease, resulting in
fewer false positives.
C. The test is highly sensitive to even the smallest changes in cellular markers.
