NSG 440 Final Exam V1 | NSG 440 Population
Health | Actual Q&A with Rationale (NSG440 Final
Exam) | Grand Canyon University
1. A community health nurse is reviewing the Social Determinants of Health (SDOH). Which
factors should the nurse identify as part of this framework? (Select all that apply)
A. Economic Stability
B. Education Access and Quality
C. Healthcare Access and Quality
D. Neighborhood and Built Environment
E. Social and Community Context
F. Individual Genetic Predispositions
Correct Answer: A, B, C, D, E
Explanation: The Social Determinants of Health framework focuses on the conditions in
which people are born, grow, live, work, and age. According to Healthy People 2030, the
five key domains are economic stability, education, healthcare access, neighborhood
environment, and social context. Genetic predispositions are typically excluded from SDOH
as they are biological rather than social or environmental factors.
2. Which intervention should the nurse classify as primary prevention?
A. Providing physical therapy to a stroke survivor
,B. Screening middle school students for scoliosis
C. Administering an influenza vaccine at a local clinic
D. Conducting a support group for patients with diabetes
Correct Answer: C
Explanation: Primary prevention aims to prevent the onset of disease or injury before it
ever occurs. Immunizations are a classic example of primary prevention because they
protect individuals from developing specific infections. In contrast, screenings are
secondary prevention, and rehabilitation or support groups for existing conditions are
tertiary prevention.
3. A nurse is calculating the prevalence of a disease. Which data point is most essential for
this calculation?
A. The number of new cases diagnosed in the last month
B. The rate at which the disease is spreading among teenagers
C. The total number of deaths caused by the disease
D. The number of existing cases in the population at a specific time
Correct Answer: D
Explanation: Prevalence refers to the total number of cases, both new and existing, within
a population at a specific point in time. This differs from incidence, which only counts new
, cases within a specific timeframe. Understanding prevalence helps public health officials
determine the overall burden of a disease on a community’s resources.
4. During a windshield survey, which observation would provide the best evidence of a
community’s socioeconomic status? (Select all that apply)
A. The presence of well-maintained parks and green spaces
B. The types of grocery stores and food availability
C. The condition of housing and public infrastructure
D. The location of public transportation stops
E. The number of churches in the residential area
Correct Answer: A, B, C, D
Explanation: A windshield survey is an informal tool used by nurses to observe
community dynamics while driving or walking through an area. Observations regarding
housing quality, food access (food deserts vs. markets), and public infrastructure directly
reflect the economic health of the neighborhood. While religious institutions are important
for social context, they are not primary indicators of socioeconomic status compared to the
other variables.
5. A community is in the ‘mitigation’ phase of disaster management. Which action is the
nurse likely performing?
A. Triaging victims at the site of a chemical spill
B. Organizing a community-wide disaster drill
