NUR 510 Exam 2 | Q&A | 2026/2027 | Public Health Nursing Theory
and Role | ASU |
1. A community health nurse is applying an upstream approach to address
health disparities. Which intervention best exemplifies this approach?
A) Providing free meals to food-insecure families
B) Conducting a health fair at a local church
C) Advocating for policies that increase the minimum wage
D) Referring a client to a food bank
Correct Answer: Advocating for policies that increase the minimum wage
Rationale: Upstream approaches address the root causes of health problems,
such as poverty and social inequality. Policy advocacy, like increasing the
minimum wage, targets these root causes. Downstream approaches
(providing meals, referrals) address immediate needs without tackling the
underlying structural issues.
2. A public health nurse is assessing a community's vulnerability to a
disaster. Which factor most significantly contributes to a population's
vulnerability?
A) Access to advanced medical technology
B) The presence of a local hospital
C) Poverty and social isolation
D) A high percentage of homeowners
Correct Answer: Poverty and social isolation
Rationale: Vulnerability is determined by a population's ability to anticipate,
cope with, and recover from disasters. Poverty and social isolation severely
limit access to resources, information, and support, making populations more
,vulnerable. Access to technology and hospitals are resources that reduce
vulnerability.
3. A community health nurse is planning a program for a vulnerable
population. Which group is most accurately described as a vulnerable
population?
A) Individuals living in a wealthy suburban community
B) A group of healthy young adults
C) Individuals with chronic mental illness who are homeless
D) A group of middle-aged professionals with health insurance
Correct Answer: Individuals with chronic mental illness who are homeless
Rationale: Vulnerable populations are those with increased risk for poor
health outcomes due to socioeconomic, environmental, or personal factors.
Homeless individuals with chronic mental illness face multiple intersecting
risk factors. Wealthy, healthy, and insured populations have greater
resources and are less vulnerable.
4. A nurse is using the socio-ecological model to address a community health
issue. At which level of the model would the nurse address the influence of
community organizations and institutions?
A) Intrapersonal level
B) Interpersonal level
C) Organizational level
D) Policy level
Correct Answer: Organizational level
,Rationale: The socio-ecological model includes multiple levels: intrapersonal
(individual), interpersonal (relationships), organizational (institutions and
organizations), community (relationships between organizations), and policy.
Community organizations and institutions, such as schools or churches, are
at the organizational level.
5. A community health nurse is using Milio's Framework for Prevention.
According to this framework, what is the primary focus for improving
population health?
A) Changing individual health behaviors through education
B) Increasing access to healthcare services for the uninsured
C) Making healthy choices the easier choices through policy and
environmental change
D) Developing new medical treatments for chronic diseases
Correct Answer: Making healthy choices the easier choices through policy
and environmental change
Rationale: Milio's Framework for Prevention posits that population health is
improved by creating environments that make healthy choices easier. This
focuses on policy and environmental changes rather than solely on individual
behavior change. Access to care and medical treatments are important but
do not address the root causes of health behaviors.
6. A public health nurse is assessing the health status of a community. Which
measure is most useful for understanding the burden of a chronic disease in
the population?
A) Incidence rate
B) Prevalence rate
C) Case fatality rate
D) Mortality rate
, Correct Answer: Prevalence rate
Rationale: Prevalence measures the total number of existing cases of a
disease in a population at a given time. It is useful for understanding the
overall burden of chronic diseases. Incidence measures new cases, case
fatality measures deaths among cases, and mortality measures deaths in the
population.
7. An epidemiologist is investigating a cluster of cancer cases in a small
town. Which type of study design is most appropriate for identifying potential
risk factors when the disease is rare?
A) Cohort study
B) Case-control study
C) Randomized controlled trial
D) Cross-sectional study
Correct Answer: Case-control study
Rationale: Case-control studies are efficient for studying rare diseases. They
start with cases (individuals with the disease) and select controls (individuals
without the disease) to compare past exposures. Cohort studies require large
samples for rare diseases, RCTs are not ethical for identifying risk factors,
and cross-sectional studies assess prevalence.
8. A community health nurse is applying the principles of cultural
competence. Which action best demonstrates cultural humility?
A) Memorizing key cultural facts about a specific ethnic group
B) Assuming all members of a culture share the same beliefs
C) Recognizing one's own biases and limitations in understanding another's
culture
