NR-442/NR442 Exam 3 V3 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is identifying activities that belong to the mitigation phase of
the disaster management cycle. Which of the following is an example of mitigation?
A. Conducting a community disaster drill to test emergency response systems.
B. Strengthening building codes to withstand high winds in hurricane-prone areas.
C. Coordinating search and rescue efforts immediately after a tornado.
D. Providing long-term counseling to survivors of a mass casualty event.
Correct Answer: B
Explanation: Mitigation refers to activities that prevent a disaster or reduce the damaging
effects of an unavoidable disaster. Strengthening building codes is a proactive measure
taken before an event to minimize structural damage. This phase focuses on long-term
strategies to protect lives and property from future disasters.
2. A school nurse is educating parents about primary prevention of communicable diseases.
Which action should the nurse emphasize as the most effective primary prevention strategy?
A. Performing routine vision and hearing screenings for all students.
B. Monitoring the clinic for students presenting with symptoms of influenza.
C. Providing DOT (Directly Observed Therapy) for students with active TB.
,D. Administering scheduled immunizations according to the CDC guidelines.
Correct Answer: D
Explanation: Primary prevention aims to prevent the onset of disease through health
promotion and specific protection. Immunizations are the gold standard for preventing the
spread of communicable diseases in the school setting. By ensuring high vaccination rates,
the nurse helps maintain herd immunity and protects vulnerable students.
3. When performing a community assessment, the nurse uses the ‘windshield survey’
method. Which observation is most relevant to the ‘environmental health’ component of the
assessment?
A. The presence of public transportation routes and frequency of bus stops.
B. The number of faith-based organizations and community centers available.
C. The prevalence of grocery stores and access to fresh produce.
D. Evidence of heavy industry near residential areas and poor air quality.
Correct Answer: D
Explanation: Environmental health assessment focuses on physical factors in the
environment that can impact human health. Noticing industrial plants near homes allows
the nurse to identify potential exposure to toxins and pollutants. This observation is critical
for determining risk factors related to respiratory and chronic diseases in that specific
population.
, 4. A nurse is working with a migrant farmworker who presents with muscle weakness,
abdominal cramping, and pinpoint pupils. What should the nurse prioritize in the
assessment?
A. History of alcohol consumption and liver function tests.
B. Access to clean drinking water and sanitary facilities.
C. Inadequate nutritional intake and signs of dehydration.
D. Exposure to organophosphate pesticides during field work.
Correct Answer: D
Explanation: The symptoms described, including miosis and muscle weakness, are classic
signs of acute pesticide poisoning. Migrant farmworkers are at high risk for chemical
exposure due to the nature of their work and lack of protective equipment. Immediate
assessment and intervention for toxic exposure are necessary to prevent neurological
damage or death.
5. In the ‘I PREPARE’ mnemonic for environmental health assessments, what does the first ‘P’
represent?
A. Past medical history of the individual and their family.
B. Personal protective equipment used during home renovations.
C. Potential hazards located in the local community park.
D. Present work including exposure to chemicals or loud noises.
