NRS 425 Exam 4 V1 | NRS 425 Health Promotion
and Population Health | Actual Q&A with Rationale
(NRS425 Exam 4) | Grand Canyon University
1. A community health nurse is developing a disaster preparedness plan for a local
municipality. Which activities should be included in the preparedness phase? (Select all that
apply.)
A. Identifying local vulnerabilities and hazards.
B. Providing long-term mental health counseling to survivors.
C. Developing a clear communication and warning system.
D. Conducting emergency response drills and exercises.
E. Evaluating the effectiveness of the response effort.
F. Establishing mutual aid agreements between jurisdictions.
Correct Answer: A, C, D, F
Explanation: Disaster preparedness involves proactive planning and training to improve
the response capability of a community. Activities such as identifying hazards, establishing
communication systems, and conducting drills ensure that agencies can react quickly and
effectively. Long-term counseling occurs during the recovery phase, while evaluation is
part of the final stage of the disaster management cycle.
,2. During a mass casualty incident involving a structural collapse, a triage nurse assesses a
victim who is conscious, breathing at 24 breaths per minute, has a capillary refill of 2 seconds,
and follows simple commands despite having a fractured radius. Which color tag should the
nurse assign?
A. Red (Immediate)
B. Yellow (Delayed)
C. Green (Minor)
D. Black (Deceased)
Correct Answer: B
Explanation: The patient is assigned a yellow tag because they are stable but require care
that can be delayed for a short period. According to the START triage system, the patient
has adequate respiratory and circulatory status and follows commands, excluding them
from the ‘Red’ category. However, a fractured radius prevents them from being considered
among the ‘walking wounded’ or green tag category.
3. A nurse is working with a population of migrant farmworkers. Which factor is most likely to
act as a barrier to healthcare for this specific population?
A. Frequent mobility and seasonal relocation.
B. Excessive health insurance coverage options.
C. Strict adherence to Western medical practices.
D. Universal access to transportation in rural areas.
,Correct Answer: A
Explanation: Migrant farmworkers often face significant barriers due to their mobile
lifestyle, which disrupts continuity of care. Frequent relocation makes it difficult to
maintain health records or follow up on chronic conditions. Additionally, linguistic
differences and fear of legal repercussions often further isolate this population from
standard healthcare services.
4. Which action by the community health nurse represents a tertiary prevention strategy for
chronic obstructive pulmonary disease (COPD)?
A. Distributing pamphlets about the dangers of smoking at a high school.
B. Performing pulmonary function tests at a local health fair.
C. Lobbying for cleaner air legislation in the metropolitan area.
D. Facilitating a pulmonary rehabilitation support group for diagnosed patients.
Correct Answer: D
Explanation: Tertiary prevention focuses on managing an established disease to prevent
further deterioration and improve quality of life. Facilitating a rehabilitation group helps
patients with existing COPD manage their symptoms and reduce complications. Primary
prevention focuses on avoiding the disease altogether, while secondary prevention focuses
on early detection through screening.
, 5. A nurse is investigating an outbreak of foodborne illness in a community. In the
epidemiological triangle, a contaminated water supply used to wash produce represents
which component?
A. The Host
B. The Agent
C. The Vector
D. The Environment
Correct Answer: D
Explanation: The environment consists of all external factors that allow the agent and host
to interact. In this scenario, the contaminated water acts as the environmental medium that
introduces the pathogen to the food and eventually the human host. Understanding these
interactions is critical for implementing control measures to stop the spread of infection.
6. When assessing a rural community, the nurse notes high rates of chronic disease and
limited access to specialty care. Which characteristic is typically associated with rural health
populations? (Select all that apply.)
A. Higher rates of obesity and sedentary lifestyles.
B. Lower levels of educational attainment compared to urban areas.
C. Increased availability of public transportation.
D. Higher prevalence of uninsured individuals.
