NR-442/NR442 Final Exam V1 | Community Health
Nursing Q&A with Rationale | Chamberlain
University
1. A community health nurse is conducting a screening for scoliosis at a local middle school.
Which level of prevention is the nurse performing?
A. Primary prevention
B. Tertiary prevention
C. Secondary prevention
D. Quaternary prevention
Correct Answer: C
Explanation: Secondary prevention focuses on early detection and screening to identify
health conditions in their early stages. Scoliosis screening in schools is a classic example of
identifying a potential problem before it progresses. By detecting it early, interventions can
be implemented to prevent further complications or disability.
2. Which of the following components represents the ‘Agent’ in the epidemiological triangle
when discussing Influenza?
A. The Influenza virus
B. A crowded shopping mall
C. The human respiratory system
,D. The patient’s age and immune status
Correct Answer: A
Explanation: The epidemiological triangle consists of the agent, the host, and the
environment. The agent is the animate or inanimate factor that must be present for a
disease or condition to develop, which in this case is the virus itself. The host refers to the
human, and the environment includes external factors like crowds.
3. A nurse is working with a vulnerable population in a rural community. Which barrier to
healthcare is most commonly associated with rural settings?
A. Excessive number of specialized clinics
B. Overabundance of primary care providers
C. High availability of public transit
D. Lack of transportation and long distances to facilities
Correct Answer: D
Explanation: Rural communities often face significant geographic isolation and a shortage
of healthcare professionals. Lack of reliable transportation prevents residents from
accessing distant clinics for both routine and emergency care. This barrier frequently leads
to delayed diagnosis and poorer health outcomes compared to urban populations.
4. A community nurse is investigating an outbreak of foodborne illness. Which step should
the nurse take first?
A. Administer antibiotics to all exposed individuals
, B. Close all local restaurants immediately
C. Identify the common source of the exposure
D. Create a brochure about handwashing
Correct Answer: C
Explanation: The first step in outbreak investigation is to establish the existence of an
outbreak and identify the source. Determining the common exposure allows the nurse to
implement targeted control measures and prevent further cases. Education and treatment
follow once the specific threat and population at risk are identified.
5. A nurse is performing a windshield survey. What is the primary purpose of this assessment
tool?
A. To gain a subjective overview of the community’s environment and resources
B. To conduct in-depth interviews with city officials
C. To perform physical exams on homeless individuals
D. To review hospital discharge data for the previous year
Correct Answer: A
Explanation: A windshield survey is an observational method used to gather data about a
community while driving through it. It provides a ‘snapshot’ of the physical environment,
housing quality, and available services. This preliminary assessment helps the nurse
identify areas that require more intensive investigation or resource allocation.
