NR442/NR 442 Exam 2 V3 | Community
Health Nursing Q&A with Rationale |
Chamberlain University
1. A community health nurse is using the epidemiological triad to analyze a recent outbreak
of influenza. Which of the following factors should the nurse identify as the ‘host’?
A. The influenza virus
B. Cold weather temperatures
C. An elderly resident with a weakened immune system
D. A crowded daycare center
Correct Answer: C
Expert Explanation: The host is the living being that the agent or environment influences.
In the epidemiological triad, the elderly resident represents the susceptible host who may
contract the disease. This model helps nurses understand the complex relationships
between the agent, the host, and the environment to develop effective interventions.
2. Which of the following actions is an example of primary prevention for a nurse working in a
community health clinic?
A. Providing physical therapy for a client recovering from a stroke
B. Screening a client for hypertension during a health fair
C. Teaching a client with diabetes how to monitor blood glucose
,D. Administering a flu vaccine to an adolescent
Correct Answer: D
Expert Explanation: Primary prevention focuses on preventing the initial occurrence of a
disease or injury. Administering a vaccine is a classic primary prevention strategy because
it builds immunity before exposure. This level of intervention is crucial for maintaining the
health of the community and reducing the overall burden of disease.
3. A nurse is triaging victims of a chemical plant explosion. A victim is conscious but has a
respiratory rate of 28, a radial pulse of 110, and follows simple commands. Which color tag
should the nurse assign?
A. Red (Immediate)
B. Green (Minor)
C. Yellow (Delayed)
D. Black (Expectant)
Correct Answer: C
Expert Explanation: Yellow tags are assigned to victims whose injuries are significant but
not yet life-threatening. Since the victim’s respiratory rate is under 30 and they can follow
commands, they do not meet the criteria for a red tag. This classification allows healthcare
providers to prioritize the most critical patients during a mass casualty incident.
,4. A nurse is investigating a potential lead hazard in a home built in 1965. Which of the
following instructions should the nurse provide to the parents of a toddler living there?
A. ‘Use hot tap water for mixing infant formula.’
B. ‘Wet-mop floors and windowsills regularly to reduce dust.’
C. ‘Vacuum daily using a standard vacuum cleaner to pick up paint chips.’
D. ‘Sand down any peeling paint to smooth the surface.’
Correct Answer: B
Expert Explanation: Wet-mopping helps minimize the spread of lead-contaminated dust,
which is a common source of exposure for children. Using hot tap water is discouraged as it
may contain higher levels of lead leached from pipes. Dry sanding or standard vacuuming
can actually aerosolize lead particles, increasing the risk of inhalation.
5. A community health nurse is planning a program for migrant farmworkers. Which of the
following barriers to healthcare should the nurse prioritize addressing?
A. Lack of interest in preventive health services
B. Universal health insurance coverage for all workers
C. Adequate transportation options in rural areas
D. Frequent movement and lack of a permanent address
Correct Answer: D
, Expert Explanation: Migrant farmworkers often face significant barriers due to their
mobile lifestyle and lack of residency status. These factors make it difficult to establish a
medical home or receive consistent follow-up care for chronic conditions. The nurse must
develop flexible programs that account for the transitory nature of this population’s work.
6. Which assessment finding should a nurse recognize as a potential sign of elder neglect?
A. A well-groomed appearance during a surprise visit
B. Pressure ulcers that have not been treated
C. Consistent attendance at all medical appointments
D. A client who is knowledgeable about their medications
Correct Answer: B
Expert Explanation: Untreated pressure ulcers or poor hygiene are significant indicators
of physical neglect in the elderly. Neglect occurs when a caregiver fails to provide
necessary care, such as food, clothing, or medical treatment. Nurses are mandated
reporters and must document such findings and notify the appropriate protective services.
7. A nurse is reviewing the ‘IPREPARE’ mnemonic for environmental health assessments.
What does the first ‘P’ in this mnemonic stand for?
A. Present work
B. Physical environment
C. Personal health history
