NR-442/NR442 Exam 4 V3 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is planning a presentation on disaster management. Which of
the following activities should the nurse include as an example of disaster mitigation?
A. Implementing a program to reinforce local infrastructure against earthquakes.
B. Developing a plan for the evacuation of residents in a flood zone.
C. Organizing a community-wide disaster drill for emergency personnel.
D. Providing immediate medical care to survivors in the impact zone.
Correct Answer: A
Explanation: Disaster mitigation involves taking proactive steps to prevent or reduce the
risk and impact of a disaster before it occurs. Reinforcing infrastructure is a physical
measure taken to lessen future damage. This differs from preparedness, which focuses on
planning and training for the event itself.
2. Using the START triage system during a mass casualty incident, which color tag should the
nurse assign to a client who is unconscious but begins breathing at 15/min after the airway is
opened?
A. Red
B. Yellow
,C. Green
D. Black
Correct Answer: A
Explanation: In the START triage system, a red tag indicates an immediate priority for life-
threatening injuries. If a patient is not breathing initially but starts breathing after airway
maneuvers, they are classified as Red. This indicates that the client requires immediate
intervention to survive but has a viable status.
3. A nurse is using the I-PREPARE mnemonic to assess a client’s environmental exposure.
What does the ‘R’ in the mnemonic stand for?
A. Residence
B. Radiological exposure
C. Referrals and Resources
D. Risk assessment
Correct Answer: C
Explanation: The ‘R’ in the I-PREPARE mnemonic represents Referrals and Resources,
which is a critical step in providing follow-up care for environmental concerns. This step
ensures that the client is connected with specialists or agencies that can mitigate
environmental hazards. Nurses use this framework to systematically collect environmental
health history from individuals.
, 4. A nurse is working in a rural community where many residents are migrant farmworkers.
Which of the following is the primary barrier to healthcare access for this population?
A. Frequent movement and lack of a permanent address.
B. A lack of interest in preventative healthcare measures.
C. Strict adherence to traditional folk medicine practices.
D. Preference for using emergency departments for primary care.
Correct Answer: A
Explanation: Migrant farmworkers often face significant barriers to healthcare due to
their mobile lifestyle, which prevents continuity of care. Frequent relocation makes it
difficult to establish long-term relationships with healthcare providers or follow up on
chronic conditions. Additionally, language barriers and lack of transportation often
exacerbate these access issues.
5. An occupational health nurse is conducting a secondary prevention activity at a
manufacturing plant. Which action should the nurse take?
A. Providing education on proper lifting techniques to prevent back injuries.
B. Coordinating physical therapy for an employee recovering from a stroke.
C. Screening employees for high blood pressure during a health fair.
D. Developing an emergency evacuation plan for the facility.
Correct Answer: C
