NUR 510 Exam 1 | Q&A | 2026/2027 | Public Health Nursing Theory
and Role | ASU | Graded A+
1. A community health nurse is applying the core functions of public health.
Which activity best represents the function of assessment?
A) Developing a policy to reduce tobacco use in public spaces
B) Ensuring that a local health department has adequate staffing
C) Conducting a community health needs assessment
D) Implementing a vaccination program at a community clinic
Correct Answer: Conducting a community health needs assessment
Rationale: The core functions of public health are assessment, policy
development, and assurance. Assessment involves systematically collecting
data on the population, monitoring health status, and diagnosing community
health problems. Policy development involves creating policies, and
assurance involves ensuring services are available.
2. A graduate nursing student is differentiating between community-oriented
nursing and community-based nursing. Which statement accurately
describes community-oriented nursing?
A) Focuses on illness care for individuals and families
B) Has the community or population as the primary client
C) Is provided in acute care settings such as hospitals
D) Emphasizes treatment of existing health problems
Correct Answer: Has the community or population as the primary client
Rationale: Community-oriented nursing has the community or population as
the primary client and focuses on health promotion and disease prevention.
,Community-based nursing is provided in community settings and focuses on
illness care for individuals and families.
3. A public health nurse is using the epidemiological triangle to analyze the
spread of a disease. Which component of the triad represents the external
factors that allow the disease to be transmitted?
A) Agent
B) Host
C) Environment
D) Vector
Correct Answer: Environment
Rationale: The epidemiological triad consists of agent, host, and
environment. The environment includes external factors such as climate,
sanitation, and social conditions that influence disease transmission. The
agent is the cause of the disease, and the host is the susceptible individual.
4. A nurse is calculating the incidence rate of a disease in a community.
Which formula should the nurse use?
A) Number of new cases / Population at risk × 1,000
B) Number of existing cases / Total population × 1,000
C) Number of deaths from disease / Number of cases × 100
D) Number of cases / Population exposed × 100
Correct Answer: Number of new cases / Population at risk × 1,000
Rationale: Incidence rate measures the number of new cases of a disease in
a population at risk over a specific time period. Prevalence measures existing
,cases, case fatality measures deaths among cases, and attack rate measures
the proportion of exposed people who become ill.
5. A community health nurse is conducting a windshield survey. Which type
of data is the nurse primarily collecting?
A) Secondary data from vital statistics
B) Primary data through direct observation
C) Data from key informant interviews
D) Data from focus groups
Correct Answer: Primary data through direct observation
Rationale: A windshield survey involves direct observation of a community by
driving or walking through it. The nurse collects primary data about housing,
transportation, businesses, and other visible community characteristics. Key
informant interviews and focus groups are other methods of primary data
collection.
6. A nurse is using the PRECEDE-PROCEED model to plan a community health
program. Which phase of the model involves identifying the health problem
and its causes through epidemiological data?
A) Phase 1: Social assessment
B) Phase 2: Epidemiological assessment
C) Phase 3: Behavioral and environmental assessment
D) Phase 4: Educational and ecological assessment
Correct Answer: Phase 2: Epidemiological assessment
Rationale: The PRECEDE-PROCEED model has eight phases. Phase 2, the
epidemiological assessment, involves identifying the health problem and its
, causes by analyzing morbidity, mortality, and other health data. Phase 1 is
social assessment, Phase 3 is behavioral and environmental assessment, and
Phase 4 is educational and ecological assessment.
7. A public health nurse is advocating for policy change to improve
community health. Which action is most consistent with the policy
development core function of public health?
A) Conducting a community health survey
B) Analyzing mortality data to identify trends
C) Testifying before a legislative committee about the need for smoke-free
policies
D) Ensuring that immunizations are available at a community clinic
Correct Answer: Testifying before a legislative committee about the need for
smoke-free policies
Rationale: Policy development involves creating and advocating for policies
that protect and promote health. Testifying before a legislative committee is
an example of policy advocacy. Conducting surveys and analyzing data are
assessment functions, and ensuring availability of services is assurance.
8. An epidemiologist is investigating an outbreak of foodborne illness at a
community picnic. Which measure is most useful for determining the speed
at which the disease is spreading?
A) Prevalence rate
B) Attack rate
C) Incidence rate
D) Case fatality rate
Correct Answer: Attack rate
