Question 1: A community health nurse is conducting a windshield survey in a rural
neighborhood. Which observation would MOST likely indicate a potential
environmental health hazard?
A. Well-maintained sidewalks and street lighting
B. Multiple fast-food restaurants within a two-block radius
C. A visible plume of smoke emanating from a nearby industrial facility
D. A community garden with raised planting beds
CORRECT ANSWER: C. A visible plume of smoke emanating from a nearby
industrial facility
Rationale: Environmental health hazards include air pollution from industrial sources,
which can directly impact respiratory health and increase risk for chronic diseases.
While food deserts (option B) represent a social determinant of health, the visible
smoke plume represents an immediate, identifiable environmental hazard requiring
assessment and potential intervention. Windshield surveys are designed to identify
such observable environmental risks that may affect community health outcomes.
Question 2: When applying the epidemiological triad to investigate a tuberculosis
outbreak in a homeless shelter, which component represents the "host" factor?
A. Mycobacterium tuberculosis bacillus
B. Overcrowded sleeping quarters with poor ventilation
C. Individuals with compromised immune systems due to malnutrition or HIV
D. Delayed diagnosis due to limited access to healthcare services
CORRECT ANSWER: C. Individuals with compromised immune systems due to
malnutrition or HIV
Rationale: In the epidemiological triad (agent, host, environment), the host refers to the
human or animal that harbors the disease. Factors such as immunosuppression, age,
genetic predisposition, or comorbidities influence host susceptibility. Option A
represents the agent, option B represents the environment, and option D represents a
health system factor that may influence disease transmission but is not a core triad
component.
,Question 3: A community health nurse is planning a health promotion program for
adolescents focused on preventing substance use. Which theoretical framework
would BEST support a program emphasizing peer influence and social norms?
A. Health Belief Model
B. Social Cognitive Theory
C. Transtheoretical Model of Change
D. Pender's Health Promotion Model
CORRECT ANSWER: B. Social Cognitive Theory
Rationale: Social Cognitive Theory emphasizes reciprocal determinism between
personal factors, behavior, and the environment, with particular attention to
observational learning, self-efficacy, and social norms. Peer influence is a central
construct, making it ideal for adolescent substance use prevention. The Health Belief
Model focuses on perceived susceptibility and benefits; the Transtheoretical Model
addresses stages of change; Pender's model emphasizes individual characteristics and
experiences influencing health-promoting behaviors.
Question 4: During a community assessment, a nurse identifies that 40% of
residents in a low-income neighborhood lack access to affordable fresh produce.
This finding BEST represents which social determinant of health?
A. Healthcare access and quality
B. Economic stability
C. Neighborhood and built environment
D. Social and community context
CORRECT ANSWER: C. Neighborhood and built environment
Rationale: The neighborhood and built environment domain includes access to healthy
foods, quality of housing, crime and violence, and environmental conditions. Lack of
affordable fresh produce relates directly to food access within the physical community
setting. Economic stability (option B) refers to employment, wages, and financial
resources; healthcare access (option A) involves insurance and provider availability;
social context (option D) includes discrimination, social cohesion, and civic
participation.
Question 5: A community health nurse is evaluating the effectiveness of a
hypertension screening program. Which outcome measure would BEST indicate
program impact at the population level?
A. Number of individuals who attended the screening event
B. Percentage of screened individuals with blood pressure readings in the hypertensive
range
C. Reduction in the community-wide prevalence of uncontrolled hypertension over 12
months
D. Participant satisfaction scores on post-screening surveys
,CORRECT ANSWER: C. Reduction in the community-wide prevalence of
uncontrolled hypertension over 12 months
Rationale: Population-level impact is best measured by changes in disease prevalence
or health status across the entire community over time. While attendance (A), screening
results (B), and satisfaction (D) are important process and short-term outcome
measures, only a reduction in community-wide prevalence of uncontrolled
hypertension demonstrates that the screening program contributed to meaningful,
sustained health improvement at the population level, aligning with core public health
goals.
Question 6: Which action by a community health nurse BEST demonstrates the
ethical principle of justice when allocating limited influenza vaccine supplies
during a shortage?
A. Prioritizing vaccines for healthcare workers regardless of community risk level
B. Distributing vaccines based on a first-come, first-served basis at the clinic
C. Using a standardized risk-assessment tool to prioritize high-risk populations and
essential workers
D. Reserving vaccines exclusively for individuals who can provide proof of insurance
CORRECT ANSWER: C. Using a standardized risk-assessment tool to prioritize high-
risk populations and essential workers
Rationale: Justice in public health ethics requires fair, equitable, and appropriate
distribution of benefits and burdens. Using an evidence-based, transparent risk-
assessment tool ensures that those at greatest risk for severe complications or those
critical to community functioning receive priority, promoting fairness and maximizing
public health benefit. Options A, B, and D introduce bias, inequity, or barriers that
disproportionately disadvantage vulnerable populations.
Question 7: A community health nurse is collaborating with local leaders to
address high rates of childhood asthma in an urban neighborhood. Which
intervention aligns with PRIMARY prevention?
A. Providing inhaler technique education to children diagnosed with asthma
B. Advocating for policy changes to reduce industrial emissions in the area
C. Coordinating home visits for children with frequent asthma exacerbations
D. Screening school-aged children for undiagnosed respiratory symptoms
CORRECT ANSWER: B. Advocating for policy changes to reduce industrial
emissions in the area
Rationale: Primary prevention aims to prevent disease before it occurs by reducing or
eliminating risk factors. Reducing environmental triggers like industrial emissions
addresses the root cause of asthma development in susceptible children. Options A
and C represent tertiary prevention (managing established disease), while option D
represents secondary prevention (early detection and intervention).
, Question 8: When conducting a cultural assessment with a newly arrived refugee
family, which approach by the community health nurse BEST demonstrates cultural
humility?
A. Using a standardized cultural checklist to quickly categorize the family's beliefs and
practices
B. Assuming the family prefers a same-gender provider based on country of origin data
C. Asking open-ended questions to learn about the family's health beliefs, preferences,
and goals
D. Providing written health materials translated into the family's native language without
verbal discussion
CORRECT ANSWER: C. Asking open-ended questions to learn about the family's
health beliefs, preferences, and goals
Rationale: Cultural humility is a lifelong process of self-reflection, recognizing power
imbalances, and partnering with individuals to provide respectful care. It emphasizes
learning from the patient rather than applying stereotypes or checklists. Option C
fosters collaborative dialogue and individualized care. Options A and B risk
stereotyping; option D, while helpful, is insufficient without interpersonal engagement
and assessment of health literacy and preferences.
Question 9: A community health nurse is designing a diabetes self-management
education program for older adults with limited health literacy. Which instructional
strategy is MOST appropriate?
A. Distributing detailed pamphlets with medical terminology and complex graphs
B. Using teach-back method with simple visuals and hands-on demonstration of
glucose monitoring
C. Delivering a 60-minute lecture covering pathophysiology, pharmacology, and diet
D. Providing a list of reputable websites for participants to research independently
CORRECT ANSWER: B. Using teach-back method with simple visuals and hands-on
demonstration of glucose monitoring
Rationale: The teach-back method confirms understanding by asking learners to
explain or demonstrate information in their own words, which is highly effective for
individuals with limited health literacy. Simple visuals and hands-on practice enhance
comprehension and retention. Options A, C, and D rely on advanced literacy, abstract
reasoning, or independent navigation of complex information, creating barriers to
learning and self-efficacy.
Question 10: Which statement by a community health nurse BEST reflects an
understanding of the difference between community-oriented and community-
based nursing practice?
A. "I provide direct care to individuals in their homes, focusing on their specific medical
needs."
