NUR 426 Exam 4: Community Health Nursing Theory &
Application V3 - Arizona College Updated and Latest
Questions and Correct Answers with Rationale
1. A community health nurse is conducting a windshield survey of a local neighborhood. Which of the
following observations would most likely indicate a social determinant of health issue regarding nutrition?
A. A large park with well-maintained walking trails.
B. A high density of fast-food restaurants and a lack of grocery stores.
C. The presence of several community-based medical clinics.
D. Diverse ethnic grocery stores offering specialty produce.
Ans: B
Explanation: Social determinants of health include the physical environment and access to resources like
nutritious food. A neighborhood with excessive fast-food options and no fresh produce retailers is often
termed a food desert. This environment significantly increases the risk for chronic conditions such as
obesity and diabetes. The nurse must identify these structural barriers to health during a windshield
survey to plan effective interventions. Addressing these issues requires a multi-sectoral approach to
improve community-wide nutritional access.
2. In the epidemiological triangle, which of the following is considered an environmental factor?
A. The level of humidity and temperature in a specific region.
B. The genetic susceptibility of the human population.
C. A bacterial pathogen such as Mycobacterium tuberculosis.
D. The immune status of children receiving vaccinations.
Ans: A
,Explanation: The epidemiological triangle consists of the agent, the host, and the environment.
Environmental factors are external conditions that affect the agent and the opportunity for exposure.
Temperature and humidity are physical environmental factors that can influence the survival of
pathogens. Unlike the agent, which is the cause, or the host, which is the victim, the environment bridges
the interaction between them. Nurses use this model to identify where to break the chain of disease
transmission.
3. A nurse is planning a secondary prevention activity for a community with high rates of hypertension.
Which action should the nurse take?
A. Lobbying for a tax on sugar-sweetened beverages in the city.
B. Providing nutrition education on low-sodium diets to healthy adults.
C. Assisting stroke survivors with physical therapy exercises.
D. Organizing a blood pressure screening event at a local mall.
Ans: D
Explanation: Secondary prevention focuses on early detection and intervention to limit the severity of a
condition. Screening for high blood pressure is a classic example of identifying asymptomatic individuals
in the early stages of disease. Primary prevention involves education or policy changes to prevent the
disease from occurring at all. Tertiary prevention aims to rehabilitate individuals who already have
complications from the disease. The nurse’s role in secondary prevention is vital for reducing long-term
morbidity in the community.
4. During a disaster response, the nurse uses the START triage system. Which patient should be tagged with
a RED tag?
A. An adult who is walking around looking for family members.
B. A patient with a respiratory rate of 32/min and a weak pulse.
, C. A victim with no respirations after an airway is opened.
D. A victim with a broken leg who is able to follow simple commands.
Ans: B
Explanation: The red tag indicates an immediate priority for victims with life-threatening but treatable
injuries. A respiratory rate over 30 per minute is a primary indicator for a red tag in the START system.
Green tags are for the ‘walking wounded,’ while black tags are for the deceased or expectant. Yellow tags
are for those whose treatment can be delayed without immediate threat to life. Nurses must perform
rapid assessments to ensure the most efficient use of limited resources during a mass casualty.
5. A nurse is applying the ‘I PREPARE’ mnemonic for an environmental health assessment. What does the
first ‘P’ represent?
A. Population demographics
B. Psychological health
C. Potential pollutants
D. Present work
Ans: D
Explanation: The ‘I PREPARE’ mnemonic is a tool used by nurses to systematically evaluate
environmental exposures. The first ‘P’ stands for ‘Present work,’ which investigates current occupational
hazards. This assessment helps determine if a patient’s symptoms are linked to chemicals or stressors at
their job. Other components include past work, residence, and environmental concerns. Using this
framework ensures that critical environmental data is not overlooked during the clinical history.
