1. A public health nurse is analyzing a sudden increase in gastrointestinal illness within a specific
neighborhood. After mapping the cases, the nurse determines that all affected individuals rely on
the same community well. Which action should the nurse prioritize to prevent further
transmission?
A. Administer prophylactic antibiotics to all neighborhood residents.
B. Issue a boil-water advisory and coordinate with environmental health to test the water
supply.
C. Conduct a door-to-door survey to identify the specific pathogen.
D. Recommend that residents transition to bottled water exclusively until the next fiscal year.
Answer: B
, Rationale: Issuing a boil-water advisory is an immediate, evidence-based intervention to halt
transmission of waterborne pathogens. Prophylactic antibiotics are inappropriate without a
confirmed diagnosis and public health mandate. While surveying and recommending bottled
water are useful, they do not address the source of contamination as effectively or rapidly as
securing the water supply.
CORRECT ANSWER : B
2. When assessing a community to identify health disparities, which data source provides the most
accurate information regarding local social determinants of health?
A. Hospital admission logs for chronic disease management.
B. State-level mortality statistics for the past decade.
C. Local census data combined with community-based participatory research (CBPR)
interviews.
D. National health survey data extrapolated to the local population.
Answer: C
Rationale: Combining census data with CBPR allows the nurse to capture both quantitative
demographic trends and qualitative insights into the specific needs of the community. Hospital
logs and mortality data provide outcomes but lack context regarding social determinants.
National data lacks the granularity required to address specific local health disparities.
CORRECT ANSWER : C
3. A nurse is designing a primary prevention program for a population at risk for Type 2 diabetes.
Which strategy best aligns with the principles of primary prevention?
A. Implementing a screening program for early detection of hyperglycemia.
B. Facilitating community-based workshops on nutritional literacy and physical activity.
C. Providing subsidized medication for newly diagnosed patients.
D. Conducting foot exams for individuals already diagnosed with diabetes.
Answer: B
Rationale: Primary prevention focuses on preventing the onset of disease through health
promotion and risk reduction. Workshops on nutrition and exercise address these preventative
factors. Screening is secondary prevention, while medication and foot exams represent
tertiary/secondary management of existing conditions.
, CORRECT ANSWER : B
4. A community nurse is working with a group of migrant farmworkers who face significant
barriers to healthcare access. Which approach best demonstrates cultural competence in
community health nursing?
A. Enforcing standard clinic hours to ensure consistency in service delivery.
B. Providing information exclusively in English to encourage assimilation.
C. Integrating mobile health clinics that operate during evening and weekend hours at the
work site.
D. Requiring all patients to provide government-issued identification before receiving services.
Answer: C
Rationale: Cultural competence requires adapting services to meet the specific life
circumstances of the population, such as the work schedules and limited mobility of migrant
workers. Fixed hours and restrictive documentation requirements create structural barriers to
access. Using English exclusively ignores the linguistic needs of the community.
CORRECT ANSWER : C
5. When applying the epidemiological triangle to a surge in respiratory infections in a school, the
"environment" component includes which of the following?
A. The specific strain of the influenza virus.
B. The immune status of the student body.
C. The ventilation system and classroom density levels.
D. The age of the infected students.
Answer: C
Rationale: In the epidemiological triangle, the environment refers to external factors that
facilitate the transmission of the agent to the host, such as indoor air quality and crowding. The
virus is the agent, while the immune status and age are host factors.
CORRECT ANSWER : C
6. A public health nurse is advocating for a policy change to reduce lead exposure in older housing
units. Which action represents the highest level of community health intervention?
, A. Educating parents on how to clean dust in their homes.
B. Lobbying local government to mandate lead abatement in low-income housing.
C. Screening children for elevated blood lead levels.
D. Creating a brochure regarding the dangers of lead paint.
Answer: B
Rationale: Policy advocacy and environmental regulation are upstream interventions that
address the root cause of the problem for the entire population. Education and screening are
downstream, individual-level interventions that do not eliminate the environmental hazard.
CORRECT ANSWER : B
7. A nurse identifies a high prevalence of hypertension in a specific demographic within a
community. To address this using the "Social Ecological Model," the nurse should focus on:
A. Only the individual behaviors of those affected.
B. Interventions at the individual, interpersonal, community, and policy levels.
C. Providing free blood pressure cuffs to every resident.
D. Focusing exclusively on the genetic predisposition of the population.
Answer: B
Rationale: The Social Ecological Model emphasizes that health is influenced by multiple levels,
including the individual, relationships, community, and public policy. Focusing on only one level
is insufficient to address complex health issues like hypertension. Providing cuffs only addresses
individual monitoring.
CORRECT ANSWER : B
8. Which statement best reflects the ethical principle of distributive justice in public health nursing?
A. Allocating resources solely to those who can pay for services.
B. Ensuring that the most vulnerable populations receive the resources necessary to reach
health parity.
C. Distributing funds equally among all neighborhoods regardless of health need.
D. Prioritizing funding for hospitals over community-based preventive programs.
