1. A community health nurse is conducting a windshield survey. Which of the following
observations would be most indicative of the community’s socioeconomic status?
A. The location and condition of public parks
B. The types of vehicles parked in residential driveways
C. The presence of lead paint on older housing structures
D. The proximity of the nearest tertiary care hospital
Answer: B
Rationale: The types and conditions of vehicles can provide immediate visual evidence of
the residents’ purchasing power and economic stability. A windshield survey is an
observational method used to assess the environment and layout of a community. This data
helps nurses identify potential health disparities related to income and social class.
2. Which level of prevention is a nurse implementing when teaching a client with type 2
diabetes about foot care and blood sugar monitoring?
A. Primary prevention
B. Secondary prevention
C. Quaternary prevention
,D. Tertiary prevention
Answer: D
Rationale: Tertiary prevention focuses on managing disease post-diagnosis to slow or stop
its progression. Teaching foot care to a diabetic patient aims to prevent complications like
ulcers or amputations. This level of care is essential for improving the quality of life for
individuals with chronic conditions.
3. In the epidemiological triad, which component represents the factor that causes the
disease?
A. The host
B. The environment
C. The vector
D. The agent
Answer: D
Rationale: The agent is the physical, chemical, or biological factor whose presence or
absence causes the disease. In the case of an infection, the agent is typically a bacterium or
virus. Understanding the agent is critical for developing targeted treatments and vaccines
in community health.
4. A nurse is preparing a disaster preparedness seminar. Which of the following is an example
of a mitigation activity?
A. Providing psychological first aid after an earthquake
, B. Conducting a triage drill for local firefighters
C. Building a levee to prevent future flooding
D. Assisting residents to return to their homes post-disaster
Answer: C
Rationale: Mitigation involves taking long-term measures to reduce or eliminate the
impact of future disasters. Building a levee proactively addresses the risk of flooding before
an event occurs. This stage is distinct from preparedness, which focuses on readiness, and
response, which occurs during the event.
5. When assessing a vulnerable population, which factor is the single most important
predictor of poor health outcomes?
A. Poverty
B. Low educational level
C. Lack of health insurance
D. Genetic predisposition
Answer: A
Rationale: Poverty is widely recognized as the primary social determinant of health that
leads to poor outcomes. It limits access to nutritious food, safe housing, and timely medical
care. Public health nurses prioritize addressing economic barriers to improve overall
community wellness.
