NR-442/NR442 Final Exam V2 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A nurse is planning a primary prevention strategy for a local community. Which of the
following actions should the nurse include?
A. Conducting blood pressure screenings at a senior center.
B. Leading a support group for individuals recovering from substance abuse.
C. Teaching a client with diabetes how to manage their insulin.
D. Providing influenza immunizations at a community health fair.
Correct Answer: D
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease
or injury. Providing immunizations is a classic example of primary prevention as it builds
immunity before exposure. Screenings represent secondary prevention, while disease
management and support groups are considered tertiary prevention.
2. When applying the epidemiological triangle to a case of influenza, which of the following
would the nurse identify as the ‘host’?
A. An elderly resident of a long-term care facility.
B. A cold and damp climate.
C. The influenza virus.
,D. Contaminated surfaces in a public space.
Correct Answer: A
Explanation: In the epidemiological triangle, the host is the living being that the agent or
the environment influences. The virus represents the agent, and the climate or
contaminated surfaces represent the environment. Identifying the host helps the nurse
understand susceptibility factors like age or immunocompromised status.
3. A community health nurse is conducting a windshield survey. Which of the following data
points is most appropriate for this type of assessment?
A. The average income level obtained from census data.
B. The prevalence of asthma among local school children.
C. Individual medical records from the local clinic.
D. The condition of housing and presence of open green spaces.
Correct Answer: D
Explanation: A windshield survey involves an observational assessment of a community
while driving or walking through it. The nurse looks for physical signs of health or risk,
such as housing conditions, availability of parks, and environmental hazards. Census data
and medical records require secondary data analysis, not direct observation during a
windshield survey.
, 4. A nurse is triaging victims at the scene of a mass casualty incident. Which color tag should
the nurse assign to a client with a simple fracture who is able to walk?
A. Red
B. Green
C. Yellow
D. Black
Correct Answer: B
Explanation: The green tag is assigned to the ‘walking wounded’ who have minor injuries
and can wait for treatment. Red tags are for immediate life-threatening injuries, and yellow
is for urgent but not immediate needs. Using the START triage system allows nurses to
prioritize care efficiently during a disaster.
5. Which level of prevention is a nurse practicing when they perform a scoliosis screening for
middle school students?
A. Primary Prevention
B. Tertiary Prevention
C. Secondary Prevention
D. Quaternary Prevention
Correct Answer: C
