and Population Health | Actual Q&A with Rationale
(NRS425 Exam 3) | Grand Canyon University
1. A community health nurse is planning a disaster simulation for a local municipality. Which
of the following actions should be categorized under the Mitigation phase of the disaster
management cycle? (Select all that apply.)
A. Implementing land-use zoning to restrict building in floodplains
B. Strengthening public infrastructure such as bridges and power grids
C. Conducting tabletop exercises for emergency responders
D. Developing a community-wide notification system
E. Retrofitting older buildings to withstand seismic activity
F. Establishing a temporary shelter in a local gymnasium
Correct Answer: A, B, E
Explanation: Mitigation involves taking permanent or long-term measures to reduce the
impact of a disaster before it occurs. Zoning and structural reinforcements are classic
examples of mitigation because they physically prevent or lessen the damage caused by
natural hazards. Conversely, tabletop exercises and notification systems are part of the
Preparedness phase, and shelters are part of the Response phase.
,2. The nurse is assessing a community’s burden of disease using the Disability-Adjusted Life
Year (DALY) metric. Which components are required to calculate this measurement?
A. Years of potential life lost and years lived with disability
B. Prevalence of chronic disease and the average age of the population
C. Incidence rate of infectious diseases and mortality rate
D. Quality of life surveys and economic productivity loss
Correct Answer: A
Explanation: The DALY is a summary measure of population health that combines
mortality and morbidity into a single number. It is calculated by adding the Years of Life
Lost (YLL) due to premature death and the Years Lived with Disability (YLD). This metric
allows public health officials to compare the impact of different diseases across various
populations.
3. When using the ‘I PREPARE’ mnemonic to assess environmental exposure, which question
should the nurse ask to evaluate the ‘P’ representing ‘Present Work’?
A. ‘Do you have any hobbies that involve chemicals?’
B. ‘What is the age of your home?’
C. ‘Are you exposed to solvents or loud noises at your current job?’
D. ‘Where do you spend your time outside of work?’
Correct Answer: C
,Explanation: The ‘Present Work’ component of the I PREPARE mnemonic focuses on
current occupational hazards. Questions should specifically address chemicals, physical
hazards, or stressors the patient encounters during their shift. Identifying these exposures
is critical because workplace toxins can often be brought home to family members via
clothing or skin.
4. During a mass casualty incident, the nurse performs triage using the START (Simple Triage
and Rapid Treatment) model. A patient is found to be breathing at 24 breaths per minute, has
a radial pulse present, and is able to follow simple commands. 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 meets the criteria for ‘Yellow’ because they are breathing, have
perfusion, and are conscious, but they are not ‘walking wounded.’ If the patient were able
to walk to a designated area, they would be tagged Green. If they had respiratory distress
over 30 bpm or lacked a radial pulse, they would be tagged Red.
, 5. A public health nurse is addressing the Social Determinants of Health (SDOH) in a rural
community. Which factors are considered SDOH? (Select all that apply.)
A. Access to grocery stores with fresh produce
B. Genetic predisposition to type 2 diabetes
C. Quality of local housing and insulation
D. Level of education and vocational training
E. Availability of public transportation
F. Individual choices regarding tobacco use
Correct Answer: A, C, D, E
Explanation: Social Determinants of Health are the conditions in which people are born,
grow, live, work, and age. Access to healthy food, housing quality, education, and
transportation are environmental and systemic factors that impact health outcomes.
Genetic factors and personal lifestyle choices like tobacco use are considered individual
biological or behavioral factors rather than social determinants.
6. The World Health Organization (WHO) focuses on several priority areas. Which of the
following is considered a primary focus for the WHO in the context of global health
promotion?
A. Funding private healthcare systems in developed nations
B. Combating non-communicable diseases like heart disease and cancer
