Exam) | Grand Canyon University
1. A public health nurse is planning a primary prevention strategy to reduce the incidence of
obesity within a specific community. Which of the following interventions should the nurse
include?
A. Developing weight management support groups for adults with a BMI over 30.
B. Screening all middle school students for body mass index (BMI) abnormalities.
C. Providing nutrition education and physical activity programs in elementary schools.
D. Referral of obese children to pediatric endocrinologists for medical management.
Correct Answer: C
Explanation: Primary prevention aims to prevent the onset of disease or injury before it
occurs by reducing exposure to risk factors. Nutrition education and physical activity
programs are proactive measures that target the entire population of students regardless
of their current weight status. In contrast, screening is secondary prevention, while
support groups and referrals represent tertiary prevention strategies.
2. Which of the following factors are considered Social Determinants of Health (SDOH) that
impact population health outcomes? (Select all that apply)
A. Availability of safe housing and local food markets.
B. Access to educational, economic, and job opportunities.
,C. Individual genetic predisposition to chronic illness.
D. Exposure to environmental toxins and physical hazards.
E. Quality of education and job training.
F. Personal health behaviors such as tobacco use.
Correct Answer: A, B, D, E
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
outcomes. Options A, B, D, and E directly describe environmental and socioeconomic
conditions that shape health. While genetics and personal behaviors (C and F) influence
health, they are categorized as biological factors or lifestyle choices rather than social
determinants.
3. A community health nurse is evaluating the ‘Epidemiological Triangle’ to understand the
spread of a respiratory virus. Which element represents the living or nonliving species that
harbor and nourish the disease-causing agent?
A. Host
B. Agent
C. Environment
D. Vector
Correct Answer: A
,Explanation: In the epidemiological triangle, the host is the human or animal that can be
affected by the disease. The agent is the factor that causes the disease, and the environment
is the setting that allows the host and agent to interact. Understanding the host
characteristics, such as susceptibility and immunity, is crucial for developing targeted
public health interventions.
4. A nurse is working in a rural community where residents have limited access to healthcare
providers. Which of the following is a tertiary prevention intervention the nurse can
implement for patients with Type 2 Diabetes?
A. Organizing a health fair to check blood glucose levels in the general population.
B. Distributing flyers about the risks of high sugar intake at local grocery stores.
C. Immunizing community members against influenza to prevent secondary respiratory
infections.
D. Providing a foot-care clinic to prevent amputation in patients with established
neuropathy.
Correct Answer: D
Explanation: Tertiary prevention focuses on managing disease post-diagnosis to slow or
stop its progression and improve quality of life. Foot care for diabetic patients directly
addresses the prevention of complications like ulcers or amputations. Screening (A) is
secondary, and immunizations (D) or education (B) are primary prevention measures.
, 5. According to the Healthy People 2030 framework, what are the overarching goals for the
nation’s health? (Select all that apply)
A. Attain healthy, thriving lives and well-being free of preventable disease, disability,
injury, and premature death.
B. Eliminate health disparities, achieve health equity, and attain health literacy.
C. Create social, physical, and economic environments that promote attaining the full
potential for health and well-being for all.
D. Promote healthy development, healthy behaviors, and well-being across all life stages.
E. Establish a mandatory national health insurance system for all citizens.
Correct Answer: A, B, C, D
Explanation: Healthy People 2030 sets data-driven objectives to improve health and well-
being over the next decade. The first four options represent the core overarching goals
aimed at equity, environment, and life-stage health. Option E is not a goal of Healthy People
2030, as the framework focuses on health objectives rather than legislating specific
insurance structures.
6. A community health nurse calculates the number of new cases of COVID-19 in a county
over the last 30 days. Which epidemiological measure is being reported?
A. Prevalence rate
B. Incidence rate
C. Mortality rate
