NR-442/NR442 Exam 3 V2 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is conducting triage at the scene of a chemical spill. Which tag
should be assigned to a patient who is unconscious and has a respiratory rate of 8 breaths per
minute?
A. Green tag
B. Yellow tag
C. Red tag
D. Black tag
Correct Answer: C
Explanation: A Red tag is assigned to individuals who have life-threatening injuries but
high probability of survival if treated immediately. In this scenario, the client’s unconscious
state and low respiratory rate indicate a critical compromise in airway and breathing.
Under the START triage system, these patients are the highest priority for medical
attention and transport.
2. Which of the following interventions represents a secondary prevention strategy in the
event of a natural disaster?
A. Screening survivors for post-traumatic stress disorder (PTSD)
B. Developing a community-wide evacuation plan
,C. Providing long-term counseling for disaster-related grief
D. Educating families on how to assemble a disaster kit
Correct Answer: A
Explanation: Secondary prevention focuses on early detection and screening to identify
health problems at an early stage. Screening for PTSD allows the nurse to identify
individuals who are suffering from the psychological impact of the disaster before the
condition worsens. In contrast, educational planning is primary prevention, and long-term
counseling is tertiary prevention.
3. A nurse is teaching a community group about the ‘IPREPARE’ mnemonic for environmental
health assessments. What does the ‘E’ in ‘IPREPARE’ represent?
A. Education
B. Emergency response
C. Environmental exposure
D. Epidemiological data
Correct Answer: C
Explanation: The ‘E’ in the IPREPARE mnemonic stands for Environmental exposure,
which prompts the nurse to ask about potential toxins in the air, water, or soil. This tool is
essential for systematically assessing a client’s risk of exposure to hazardous materials in
their daily life. Nurses use this assessment to link health symptoms to environmental
factors such as lead, radon, or pesticides.
, 4. During a disaster response, which organization is primarily responsible for providing shelter
and meeting the basic needs of victims?
A. Centers for Disease Control and Prevention (CDC)
B. American Red Cross
C. Federal Emergency Management Agency (FEMA)
D. World Health Organization (WHO)
Correct Answer: B
Explanation: The American Red Cross is a non-governmental organization that is officially
chartered by Congress to provide disaster relief. They specialize in mass care, including
setting up shelters and providing food to individuals displaced by disasters. While FEMA
coordinates the overall federal response, the Red Cross is the primary entity for direct
social service delivery at the local level.
5. A community health nurse is evaluating the incidence of a new respiratory illness in a
town. Which definition best describes incidence?
A. The total number of existing cases in the population at a specific time
B. The proportion of the population that died from the disease
C. The number of new cases of a disease occurring in a population during a specified period
D. The geographic distribution of the illness within the town
Correct Answer: C
