Introduction
This comprehensive examination is designed to assess the advanced knowledge and clinical reasoning skills
essential for the Senior Bachelor of Science in Nursing (BSN) student in the specialized field of public health
nursing. The test encompasses a wide range of core competencies, including epidemiological principles, community
assessment, health promotion, and the ethical and legal frameworks that guide practice. Through a combination of
theoretical questions and application-based scenarios, this assessment emphasizes the synthesis of public health
science with nursing practice. It challenges students to apply critical thinking and evidence-based decision-making
,to real-world situations, preparing them for the complexities of improving population health and ensuring
equitable care for all communities.
SECTION ONE: QUESTIONS 1-100
1. A community health nurse is using the epidemiological triad to investigate an outbreak of salmonellosis.
Which component of the triad would be the focus of an intervention aimed at pasteurizing milk?
A. Host
B. Agent
C. Environment
D. Vector
🟢 B. Agent
🔴 RATIONALE: The epidemiological triad consists of the host (the susceptible human), the agent (the cause of
the disease), and the environment (external factors). Pasteurization directly targets and eliminates the biological
agent, Salmonella, thereby interrupting the chain of infection.
2. A public health nurse is planning a primary prevention strategy for cardiovascular disease in a rural
community. Which of the following interventions is the best example of this?
A. Implementing a community-wide campaign to promote physical activity and healthy eating.
B. Offering free blood pressure and cholesterol screenings at the local health fair.
C. Establishing a cardiac rehabilitation support group for post-heart attack patients.
D. Conducting a case management program for individuals with uncontrolled hypertension.
,🟢 A. Implementing a community-wide campaign to promote physical activity and healthy eating.
🔴 RATIONALE: Primary prevention aims to prevent a disease from occurring in the first place by promoting
health and reducing risk factors. A community-wide campaign targeting the general population to encourage
healthy lifestyles is a primary prevention strategy. Screenings (B) are secondary prevention, and rehabilitation
(C) and case management (D) are tertiary prevention.
3. A community health nurse is evaluating the effectiveness of a new tuberculosis (TB) directly observed
therapy (DOT) program. The primary indicator of success for this program is:
A. Increased number of patients who start the TB medication regimen.
B. Decreased number of patients who report side effects from the TB medication.
C. Increased proportion of patients who complete the full course of TB treatment.
D. Decreased number of patients requiring hospitalization for TB.
🟢 C. Increased proportion of patients who complete the full course of TB treatment.
🔴 RATIONALE: The primary goal of DOT is to ensure adherence to the full course of TB treatment, which is
critical for curing the disease, preventing relapse, and most importantly, preventing the development of drug-
resistant TB. While the other options are relevant, treatment completion is the most direct and critical measure
of program success.
4. A public health nurse is assessing a community's vulnerability to a natural disaster. Which factor is the
most significant determinant of a population's overall vulnerability?
A. The geographic location and topography of the community.
B. The availability of local emergency services and first responders.
C. The community's social and economic resources and infrastructure.
D. The history of previous natural disasters in the area.
, 🟢 C. The community's social and economic resources and infrastructure.
🔴 RATIONALE: Vulnerability is determined by a population's capacity to anticipate, cope with, resist, and
recover from the impact of a hazard. Socioeconomic factors like poverty, poor housing, lack of access to
healthcare, and weak infrastructure are the most significant determinants of high vulnerability. While other
factors are relevant, they are secondary to the social determinants of health.
5. A public health nurse is working with a population of migrant farmworkers. Which of the following ethical
principles is most challenged when providing care to this mobile and often marginalized group?
A. Beneficence
B. Non-maleficence
C. Justice
D. Autonomy
🟢 C. Justice
🔴 RATIONALE: Justice in public health refers to the fair and equitable distribution of resources, services, and
the burdens of disease. Migrant farmworkers often face significant barriers to accessing healthcare, including
language barriers, lack of insurance, and mobility, which creates a situation of health inequity and challenges
the principle of justice.
6. A community health nurse is using the Precede-Proceed model to plan a health program. The first step in
this model is to:
A. Identify the educational and ecological factors that influence a health issue.
B. Conduct a social assessment to identify the community's quality of life and needs.
C. Develop a program implementation plan and budget.
D. Evaluate the program's impact on health outcomes.
