and Population Health | Actual Q&A with Rationale
(NRS425 Exam 3) | Grand Canyon University
1. A community health nurse is reviewing the phases of a disaster. Which activity is the
primary focus of the mitigation phase?
A. Conducting search and rescue operations immediately after a disaster.
B. Providing long-term mental health counseling for survivors.
C. Developing a personal family emergency communication plan.
D. Strengthening the community’s infrastructure to prevent or reduce the impact of
potential hazards.
Correct Answer: D
Explanation: Mitigation involves taking proactive measures to prevent or reduce the
impact of a disaster before it occurs. This phase focuses on long-term risk reduction
through infrastructure improvements and policy changes. It differs from preparedness,
which focuses on readiness for an imminent or potential event.
2. Which of the following populations are considered vulnerable to health disparities and
should be prioritized by the population health nurse? (Select All That Apply)
A. Individuals experiencing homelessness.
B. Migrant farm workers.
,C. Incarcerated individuals.
D. Pregnant adolescents.
E. LGBTQ+ youth.
F. Full-time employed individuals with employer-sponsored insurance.
Correct Answer: ABCDE
Explanation: Vulnerable populations are groups that are at higher risk for poor health
outcomes due to social, economic, or environmental barriers. This includes the homeless,
migrants, the incarcerated, and marginalized youth who face significant obstacles to
accessing care. In contrast, those with stable employment and insurance typically have
lower levels of vulnerability to these specific health disparities.
3. When assessing a patient for environmental health risks, the nurse utilizes the I-PREPARE
mnemonic. What does the ‘P’ in I-PREPARE represent?
A. Personal safety.
B. Present work.
C. Psychological status.
D. Poverty level.
Correct Answer: B
Explanation: The I-PREPARE mnemonic is a tool used by nurses to facilitate data
collection regarding environmental exposures. The ‘P’ stands for ‘Present Work,’ which
,includes questions about current workplace exposures to toxins or hazards. This helps the
nurse identify if the patient’s symptoms are related to their occupational environment.
4. A nurse is participating in a disaster response drill and is assigned to the triage area. A
victim arrives with a large open abdominal wound, rapid but weak pulse, and respirations
over 30 per minute. Which color tag should the nurse assign?
A. Red (Immediate)
B. Yellow (Delayed)
C. Green (Minor)
D. Black (Expectant)
Correct Answer: A
Explanation: The Red tag is assigned to individuals who require immediate life-saving
intervention. Signs of respiratory distress (RR > 30) and circulatory instability (weak
pulse) indicate that the patient is in the ‘Immediate’ category. Failing to provide rapid
treatment to this patient would likely result in death.
5. The nurse is implementing a tertiary prevention strategy for a group of patients with Type
2 Diabetes. Which of the following is an example of this level of prevention?
A. Providing a cooking class on low-glycemic meals for newly diagnosed patients.
B. Screening all adults over age 45 for elevated blood glucose levels.
C. Leading a community-wide campaign to increase physical activity in schools.
, D. Administering insulin at a health fair to demonstrate how the drug works.
Correct Answer: A
Explanation: Tertiary prevention focuses on managing disease and preventing
complications in individuals who already have a diagnosis. A cooking class for diagnosed
diabetics helps them manage their condition and avoid long-term sequelae like neuropathy
or retinopathy. Screening is secondary prevention, while community campaigns are
primary prevention.
6. Which global health organization is primarily responsible for monitoring international
disease outbreaks and providing leadership on global health matters?
A. World Health Organization (WHO)
B. Centers for Disease Control and Prevention (CDC)
C. United Nations International Children’s Emergency Fund (UNICEF)
D. United States Agency for International Development (USAID)
Correct Answer: A
Explanation: The World Health Organization (WHO) is the leading international authority
on global public health within the United Nations system. It coordinates international
responses to health emergencies and sets standards for disease control. While the CDC
assists globally, its primary mandate is within the United States.
