NRS 425 Exam 4 V2 | NRS 425 Health Promotion
and Population Health | Actual Q&A with Rationale
(NRS425 Exam 4) | Grand Canyon University
1. Which factors are identified as Social Determinants of Health (SDOH) according to Healthy
People 2030? Select all that apply.
A. Economic Stability
B. Education Access and Quality
C. Genetic Predisposition
D. Health Care Access and Quality
E. Neighborhood and Built Environment
F. Social and Community Context
Correct Answer: A, B, D, E, F
Explanation: Social determinants of health are the conditions in the environments where
people are born, live, learn, work, play, worship, and age that affect a wide range of health,
functioning, and quality-of-life outcomes. Genetic predisposition is considered a biological
factor rather than a social determinant. Addressing these five domains is essential for
reducing health disparities and promoting health equity across populations.
,2. A community health nurse is conducting a screening for hypertension at a local senior
center. Which level of prevention does this activity represent?
A. Primary Prevention
B. Secondary Prevention
C. Tertiary Prevention
D. Quaternary Prevention
Correct Answer: B
Explanation: Secondary prevention focuses on early detection and intervention to limit
the severity of a disease. Screening programs, such as blood pressure checks or
mammograms, are classic examples of secondary prevention. The goal is to identify
individuals in the early stages of a condition so that treatment can begin promptly to
prevent complications.
3. When assessing a community, the nurse utilizes the ‘I-PREPARE’ mnemonic to identify
environmental health risks. What does the ‘E’ in I-PREPARE stand for?
A. Educate
B. Emergency preparedness
C. Environmental concerns
D. Environmental justice
Correct Answer: A
,Explanation: The ‘I-PREPARE’ mnemonic stands for Investigate, Present work, Residence,
Environmental concerns, Past work, Activities, Resources and referrals, and Educate. The
‘Educate’ component focuses on providing the patient with information to prevent future
exposures and improve their health outcomes. It is a critical final step in the environmental
health assessment process to empower the client.
4. A nurse is working with a population of migrant farmworkers. Which of the following are
common health risks or barriers to care for this group? Select all that apply.
A. Pesticide exposure
B. Lack of transportation
C. Consistent access to health insurance
D. Inadequate housing
E. Language barriers
F. Food insecurity
Correct Answer: A, B, D, E, F
Explanation: Migrant farmworkers face unique occupational hazards such as exposure to
toxic chemicals and pesticides. They often experience social barriers including language
differences and a lack of reliable transportation to health clinics. These systemic issues
contribute to poor health outcomes and require culturally sensitive nursing interventions
to address properly.
, 5. In epidemiology, the ‘Epidemiological Triangle’ consists of which three components?
A. Person, Place, and Time
B. Host, Agent, and Environment
C. Incidence, Prevalence, and Mortality
D. Primary, Secondary, and Tertiary
Correct Answer: B
Explanation: The Epidemiological Triangle is a model used to explain the development of
infectious diseases. It involves the interaction of a susceptible host, an external agent, and
an environment that facilitates the transmission. Understanding how these three factors
interact allows public health officials to develop targeted strategies for disease control.
6. Which of the following describes the ‘Incidence’ rate in a population?
A. The number of existing cases of a disease at a specific time.
B. The number of new cases of a disease in a population over a specific period.
C. The total number of deaths caused by a specific disease.
D. The proportion of the population that is immune to a disease.
Correct Answer: B
Explanation: Incidence refers specifically to the rate of new cases occurring within a
defined period. This differs from prevalence, which accounts for all existing cases (new and
