Question 1: A community health nurse is conducting a windshield survey of a
metropolitan area. Which of the following data collected during this survey is
considered primary data?
A. The age and condition of housing in the neighborhood
B. The number of public transportation stops observed
C. The presence of community gathering spaces like parks and churches
D. Direct interviews with residents about their perceived health needs
CORRECT ANSWER: D. Direct interviews with residents about their perceived
health needs
Rationale: Primary data is information collected directly from the source—in this case,
the community members themselves—through interviews, focus groups, or surveys.
Options A, B, and C are examples of secondary data, which are observable
environmental factors collected during the windshield survey but are not directly
gathered from individuals.
Question 2: A nurse is using the epidemiological triad to investigate an outbreak of
salmonella in a local community. Which component of the triad would include the
bacteria Salmonella enterica?
A. Host
B. Agent
C. Environment
D. Vector
CORRECT ANSWER: B. Agent
Rationale: The epidemiological triad consists of the agent, host, and environment. The
agent is the causative factor, such as a bacterium, virus, parasite, or chemical.
Salmonella enterica is the biological agent responsible for the illness. The host is the
human or animal that contracts the disease, and the environment includes external
factors that allow transmission.
Question 3: A community health nurse is planning a secondary prevention strategy
for diabetes in a rural clinic. Which of the following interventions best exemplifies
this level of prevention?
A. Educating school children about healthy eating habits
B. Conducting annual hemoglobin A1c screenings for at-risk adults
,C. Providing insulin therapy management education for newly diagnosed patients
D. Establishing a community garden to improve access to fresh vegetables
CORRECT ANSWER: B. Conducting annual hemoglobin A1c screenings for at-risk
adults
Rationale: Secondary prevention focuses on early detection and prompt treatment of
disease to halt progression. Screening for diabetes through HbA1c tests detects the
disease in its early stages. Option A is primary prevention, and options C and D are
tertiary and primary prevention respectively.
Question 4: Which of the following best describes the primary focus of community
health nursing as defined by the American Public Health Association (APHA)?
A. Providing direct bedside care to acutely ill patients in hospital settings
B. Promoting and preserving the health of populations by integrating community
involvement
C. Administering immunizations exclusively to pediatric populations
D. Conducting research on genetic markers for chronic diseases
CORRECT ANSWER: B. Promoting and preserving the health of populations by
integrating community involvement
Rationale: The APHA defines community health nursing as a synthesis of nursing
practice and public health practice, aimed at promoting and preserving the health of
populations. It emphasizes community involvement and is not limited to hospital care,
pediatric immunizations, or genetic research.
Question 5: A nurse is assessing a community's disaster preparedness. According
to the disaster management cycle, which phase includes activities such as
conducting evacuation drills and stockpiling emergency supplies?
A. Mitigation
B. Preparedness
C. Response
D. Recovery
CORRECT ANSWER: B. Preparedness
Rationale: The disaster management cycle includes mitigation, preparedness,
response, and recovery. The preparedness phase involves planning, training,
conducting drills, and stockpiling supplies to ensure readiness for a potential disaster.
Mitigation reduces risks, response occurs during the event, and recovery follows the
disaster.
,Question 6: A community health nurse is using the PRECEDE-PROCEED model to
develop a health promotion program. During which phase does the nurse assess
the quality of life and social indicators of the target population?
A. Phase 1 - Social Assessment
B. Phase 2 - Epidemiological Assessment
C. Phase 3 - Behavioral Assessment
D. Phase 4 - Educational Assessment
CORRECT ANSWER: A. Phase 1 - Social Assessment
Rationale: The PRECEDE-PROCEED model begins with Phase 1, the social assessment,
which evaluates the community's quality of life, social indicators, and perceived needs.
This phase identifies the broad goals of the population. The epidemiological, behavioral,
and educational assessments follow in subsequent phases.
Question 7: A nurse is evaluating the effectiveness of a needle exchange program in
reducing HIV transmission. Which type of evaluation focuses on the immediate
effects of the program on participants' knowledge and behaviors?
A. Impact evaluation
B. Outcome evaluation
C. Process evaluation
D. Formative evaluation
CORRECT ANSWER: A. Impact evaluation
Rationale: Impact evaluation measures the immediate, short-term effects of a
program, such as changes in knowledge, attitudes, or behaviors. Outcome evaluation
measures long-term health effects, such as disease incidence. Process evaluation
assesses program implementation, and formative evaluation is conducted during
program development.
Question 8: A community health nurse is providing care to a migrant farmworker
family. Which social determinant of health is most likely to have the greatest
impact on this population's health status?
A. Genetic predisposition to chronic illness
B. Access to affordable and culturally competent healthcare
C. Availability of advanced surgical interventions
D. Individual lifestyle choices regarding exercise
CORRECT ANSWER: B. Access to affordable and culturally competent healthcare
Rationale: Migrant farmworkers often face significant barriers to healthcare access due
to language, mobility, cost, and fear of immigration status. Access to care is a key social
, determinant of health. Genetics, surgical availability, and individual choices are less
dominant or modifiable compared to access barriers in this population.
Question 9: A nurse is triaging patients at a mass casualty incident. Which patient
should receive the highest priority for care based on the START triage system?
A. A patient who is ambulatory with minor lacerations
B. A patient with a respiratory rate of 8 breaths per minute
C. A patient with a palpable radial pulse and who follows commands
D. A patient with a respiratory rate of 30 breaths per minute who is confused
CORRECT ANSWER: D. A patient with a respiratory rate of 30 breaths per minute
who is confused
Rationale: In the START triage system, patients with a respiratory rate >30/min, absent
radial pulse, or altered mental status are categorized as immediate (red tag) and require
priority care. Option D meets two immediate criteria: tachypnea and confusion. Option
B is respiratory failure (black tag), and option C is stable (green).
Question 10: A community health nurse is developing a program to address obesity
in school-aged children. Which theoretical framework emphasizes the interaction
between personal factors, environmental influences, and behavior?
A. Health Belief Model
B. Social Cognitive Theory
C. Transtheoretical Model
D. Theory of Planned Behavior
CORRECT ANSWER: B. Social Cognitive Theory
Rationale: Social Cognitive Theory, developed by Bandura, posits that behavior is
influenced by the dynamic interaction of personal factors (cognition, self-efficacy),
environmental factors (social and physical), and behavior itself. The Health Belief Model
focuses on perceived threats and barriers; the Transtheoretical Model emphasizes
stages of change; and the Theory of Planned Behavior centers on intentions.
Question 11: A nurse is investigating an outbreak of lead poisoning in a low-income
housing project. Which level of prevention is the nurse practicing when she tests
all children under age 6 for elevated blood lead levels?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
