NR-442/NR442 Exam 4 V1 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A nurse is working with a local community to improve disaster resilience. Which action by
the nurse represents the mitigation phase of disaster management?
A. Organizing a triage training session for first responders
B. Advocating for the reinforcement of local dams and levees
C. Performing rapid health assessments in a shelter
D. Conducting crisis counseling for disaster survivors
Correct Answer: B
Explanation: Mitigation involves activities that reduce the impact or prevent the
occurrence of a disaster. Advocating for structural reinforcements like levees is a proactive
measure to minimize flood damage. This phase occurs long before a disaster happens to
ensure community safety.
2. During a mass casualty incident, the nurse assesses a victim who is conscious, has a broken
arm, and is able to walk to the designated triage area. Which color tag should the nurse
assign?
A. Red
B. Yellow
,C. Green
D. Black
Correct Answer: C
Explanation: Green tags are assigned to the ‘walking wounded’ who have minor injuries
and can move themselves to safety. This victim has a non-life-threatening injury and is
ambulatory, fitting the criteria for the lowest priority. Proper tagging ensures that
resources are directed first to those with the most critical needs.
3. A community health nurse is assessing a migrant farmworker who presents with muscle
weakness, abdominal cramps, and excessive salivation. Which condition should the nurse
suspect?
A. Tuberculosis
B. Heat exhaustion
C. Lead poisoning
D. Pesticide exposure
Correct Answer: D
Explanation: Migrant farmworkers are at high risk for pesticide exposure, which manifests
with neurological and gastrointestinal symptoms. Symptoms such as muscle weakness and
salivation are classic signs of organophosphate toxicity. The nurse must conduct a thorough
occupational history to confirm the exposure and provide appropriate treatment.
, 4. The nurse is conducting an environmental health assessment using the ‘I PREPARE’
mnemonic. What does the ‘P’ in the mnemonic stand for?
A. Public policy
B. Population density
C. Previous work
D. Personal protective equipment
Correct Answer: C
Explanation: The ‘I PREPARE’ mnemonic is used to systematically assess environmental
exposure history. The ‘P’ stands for ‘Present work,’ while the second ‘P’ stands for ‘Past
work’ or ‘Previous work.’ Assessing a client’s work history helps identify potential long-
term exposures to toxins or hazards.
5. Which of the following populations is considered most vulnerable to the effects of
environmental pollutants due to physiological factors?
A. Adolescents
B. Pregnant women
C. Young children
D. Middle-aged adults
Correct Answer: C
