NURS 340 | NURS340 Final Exam: RN Community
Health - WCU Updated and Latest Questions and
Correct Answers with Rationale
1. A community health nurse is planning a program to reduce the incidence of obesity in
school-aged children. Which level of prevention is represented by providing healthy cooking
classes to parents?
A. Quaternary prevention
B. Secondary prevention
C. Tertiary prevention
D. Primary prevention
Correct Answer: D
Rationale: Primary prevention aims to prevent the onset of disease or injury before it
occurs. Providing education on healthy cooking helps parents establish nutritious habits
for their children to avoid obesity. This intervention targets the entire population of
parents rather than focusing on those already diagnosed. It is a proactive approach to
promoting long-term health and wellness. Therefore, it fits the definition of health
promotion and risk reduction characteristic of primary care.
2. An occupational health nurse is conducting a screening for hypertension among factory
workers. This activity represents which level of prevention?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Health maintenance
Correct Answer: A
Rationale: Secondary prevention focuses on early detection and prompt treatment of
subclinical diseases. Hypertension screening identifies individuals who may have high
blood pressure but are asymptomatic. By finding these cases early, the nurse can facilitate
medical intervention to prevent complications like stroke. Screening is a hallmark activity
within the secondary level of the public health model. It transitions care from general
health promotion to specific clinical identification.
3. Which epidemiological rate measures the number of new cases of a disease occurring in a
specific population over a designated period?
A. Prevalence rate
,B. Incidence rate
C. Attack rate
D. Mortality rate
Correct Answer: B
Rationale: Incidence rate specifically tracks the development of new cases within a
susceptible population over time. This metric is essential for understanding the speed at
which an infectious disease is spreading. It differs from prevalence, which includes both
new and existing cases at a single point. Calculating incidence helps public health officials
evaluate the effectiveness of prevention programs. High incidence rates often trigger the
need for urgent community health interventions.
4. A nurse is using the ‘I PREPARE’ mnemonic to assess a client’s environmental exposure.
What does the ‘P’ in this tool stand for?
A. Personal habits
B. Present work
C. Past work
D. Primary health history
Correct Answer: B
Rationale: The ‘I PREPARE’ tool is designed to assist nurses in identifying potential
environmental health risks. The first ‘P’ specifically stands for ‘Present work’ to evaluate
current occupational hazards. This involves asking the client about exposures to chemicals,
dust, or noise in their current job. Understanding the work environment is critical because
many chronic illnesses are linked to workplace conditions. This systematic approach
ensures that the nurse does not overlook significant environmental contributors to health.
5. When performing a windshield survey, which of the following observations would provide
information about the community’s boundaries?
A. The presence of specialized clinics and hospitals
B. Natural landmarks and man-made structures like highways
C. The condition and age of the residential housing
D. Common gathering places like parks and community centers
Correct Answer: B
Rationale: Boundaries define the geographical limits of a community and influence how
residents access services. Natural landmarks like rivers or man-made features like major
highways serve as physical markers for these limits. Identifying these boundaries helps the
nurse understand the spatial layout of the target population. This information is vital for
, planning service delivery and determining service coverage areas. It is one of the initial
steps in a comprehensive community assessment.
6. A public health nurse is reviewing the epidemiological triangle to investigate a recent
outbreak. Which component represents the factor that causes the disease?
A. Host
B. Agent
C. Environment
D. Vector
Correct Answer: B
Rationale: The agent is the physical, chemical, or biological factor whose presence or
absence causes a disease. Common biological agents include bacteria, viruses, and parasites
that lead to infectious outbreaks. The host is the living being that is affected, while the
environment is the setting where they interact. Successful disease control often involves
targeting the agent to break the cycle of transmission. This model is foundational for
understanding the multi-faceted nature of public health challenges.
7. A nurse is planning tertiary prevention interventions for a client with diabetes. Which of
the following is an example of this level of care?
A. Screening for diabetic retinopathy
B. Teaching a client how to perform daily foot exams
C. Educating the community about sugar intake
D. Providing flu vaccinations at a local senior center
Correct Answer: B
Rationale: Tertiary prevention aims to minimize the impact of long-term disease and
prevent disability. Teaching foot care to a diabetic client helps prevent complications like
ulcers or amputations. This level of care focuses on rehabilitation and management after a
diagnosis has been established. It differs from primary prevention, which avoids disease,
and secondary, which detects it. Effective tertiary care improves the quality of life for
individuals living with chronic conditions.
8. In the event of a disaster, which phase of management includes activities like conducting
drills and training volunteers?
A. Mitigation
B. Response
C. Preparedness
D. Recovery
