and Population Health | Actual Q&A with Rationale
(NRS425 Exam 4) | Grand Canyon University
1. A community health nurse is conducting a triage at the scene of a multi-vehicle accident. A
victim is unconscious, has a respiratory rate of 32 breaths per minute, and has a capillary refill
of 4 seconds. Using the Simple Triage and Rapid Treatment (START) system, which color tag
should the nurse assign?
A. Green (Minor)
B. Yellow (Delayed)
C. Black (Deceased)
D. Red (Immediate)
Correct Answer: D
Explanation: The red tag is assigned to individuals who require immediate life-saving
intervention. According to the START triage system, respiratory rates over 30 or delayed
capillary refill (over 2 seconds) indicate a critical status. Because this patient meets both
criteria, they are prioritized for immediate transport to a trauma center.
2. Which intervention represents a secondary level of prevention for a community
experiencing an outbreak of influenza?
A. Providing influenza vaccinations at a local community center.
B. Educating the public about the importance of hand hygiene.
,C. Administering antiviral medications to patients already hospitalized with pneumonia.
D. Performing rapid influenza diagnostic tests on symptomatic individuals.
Correct Answer: D
Explanation: Secondary prevention focuses on early detection and screening to limit the
impact of a disease. Testing individuals for the presence of the virus allows for early
identification and isolation to prevent further spread. Primary prevention would involve
the vaccine or education, while tertiary prevention involves treating complications like
pneumonia.
3. A nurse is working with a rural population. What are the primary barriers to healthcare
access that the nurse should anticipate in this community? (Select All That Apply)
A. Lack of public transportation systems.
B. Shortage of healthcare providers and specialists.
C. Inadequate health insurance coverage.
D. Cultural preference for traditional medicine over modern care.
E. Long travel distances to the nearest medical facility.
F. Higher costs of living compared to urban areas.
Correct Answer: A,B,C,E
Explanation: Rural health is often compromised by geographical isolation, which makes
physical access to clinics difficult without public transport. The shortage of healthcare
,professionals in these regions leads to longer wait times and decreased preventative
screenings. Additionally, rural populations often face higher rates of being uninsured or
underinsured, further complicating their ability to seek care.
4. In the epidemiological triangle, a nurse identifies that a contaminated water supply is
leading to a localized outbreak of cholera. The water supply represents which component of
the triangle?
A. Agent
B. Environment
C. Host
D. Vector
Correct Answer: B
Explanation: The environment consists of all external factors that allow the agent to reach
the host. In this scenario, the water acts as the medium or setting in which the cholera
bacteria (the agent) thrives and is transmitted. Understanding these relationships helps the
nurse implement effective environmental controls to break the chain of infection.
5. The United Nations Sustainable Development Goals (SDGs) include a target to end the
epidemics of AIDS, tuberculosis, and malaria by which year?
A. 2025
B. 2030
C. 2035
, D. 2040
Correct Answer: B
Explanation: The Sustainable Development Goals are a collection of 17 global goals
designed to be a blueprint to achieve a better and more sustainable future for all. Goal 3
specifically targets health and well-being, aiming to end major epidemics by the year 2030.
Nurses play a critical role in global health initiatives to meet these ambitious public health
targets.
6. When assessing a migrant worker community, the nurse recognizes that which of the
following is the most significant occupational health risk for this group?
A. Sedentary lifestyle diseases
B. Exposure to pesticides
C. Lack of childhood immunizations
D. High-stress corporate environments
Correct Answer: B
Explanation: Migrant workers are frequently employed in agriculture where they are
exposed to hazardous chemicals and pesticides. This exposure can lead to acute toxicity or
chronic health problems such as respiratory issues and certain cancers. Public health
interventions must focus on protective gear, education, and chemical safety standards in
these settings.
