Walden University 2025/2026
1. Which statement best defines population health?
A. The health status of a single individual within a clinical setting
B. The health outcomes of a group of individuals, including the distribution of such outcomes within the group
C. The management of hospital resources to improve patient throughput
D. A study focusing exclusively on genetic factors affecting a specific family
Correct Answer: B
Rationale: Population health focuses on the health outcomes of a defined group and examines how those
outcomes are distributed within the population. This aggregate, group-level perspective distinguishes
population health from individual-focused clinical care .
2. A public health nurse is organizing a blood pressure screening event at a community center. This is an
example of which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Correct Answer: B
,Rationale: Secondary prevention focuses on early detection and screening to identify diseases in their earliest
stages when treatment is most effective. Blood pressure screening is a classic example of secondary prevention
.
3. Which factor is considered a social determinant of health (SDOH)?
A. Genetic predisposition to Type 2 diabetes
B. Access to safe housing and local food markets
C. The presence of a BRCA1 gene mutation
D. An individual's personal choice to exercise daily
Correct Answer: B
Rationale: Social determinants of health are the conditions in the environments where people are born, live,
learn, work, and age. Access to safe housing and nutritious food are key SDOH that influence health outcomes .
4. In epidemiology, the "Triad" consists of which three components?
A. Doctor, Patient, Hospital
B. Incidence, Prevalence, Mortality
C. Assessment, Policy, Assurance
D. Agent, Host, Environment
Correct Answer: D
, Rationale: The epidemiological triad is a model used to explain the causation of infectious diseases, involving
the agent (pathogen), the host (susceptible individual), and the environment (conditions that facilitate

5. Which of the following is an example of "Upstream Thinking" in nursing?
A. Providing dialysis for a patient with end-stage renal disease
B. Treating an acute asthma attack in the emergency room
C. Advocating for laws that limit industrial pollution in a neighborhood
D. Teaching a post-stroke patient how to use a walker
Correct Answer: C
Rationale: Upstream thinking focuses on modifying the social, political, and environmental factors that lead to
poor health rather than just treating symptoms. Advocating for pollution limits addresses the root causes of
health problems .
6. What does the term "Prevalence" represent in a population?
A. The number of new cases of a disease occurring in a specific period
B. The probability that a healthy person will develop a disease
C. The number of deaths resulting from a specific disease
D. The total number of existing cases of a disease at a specific point in time
