NUR 426 Exam 3: Community Health Nursing Theory &
Application V2 - Arizona College Updated and Latest
Questions and Correct Answers with Rationale
1. A community health nurse is organizing a health fair focused on preventing the spread of communicable
diseases. Providing immunizations to school-aged children is an example of which level of prevention?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Quaternary prevention
Ans: B
Explanation: Primary prevention focus on health promotion and the prevention of the initial occurrence
of disease or injury. Immunization programs are a classic example of this level because they provide
specific protection against potential pathogens. Secondary prevention involves early detection and
screening, which is not what an immunization does. Tertiary prevention aims to reduce the limitations of
disability from existing disease. This specific action reflects the nurse’s role in proactive community
protection and health maintenance.
2. When assessing a community, the nurse performs a windshield survey. Which of the following data
points is most appropriate for this type of assessment?
A. The prevalence of diabetes among residents
B. The results of the latest census regarding income
C. Individual medical histories of local business owners
D. The condition of housing and presence of green spaces
,Ans: D
Explanation: A windshield survey is an informal tool used to observe a community’s characteristics
while driving or walking through it. The nurse looks for objective physical signs such as housing
conditions, public transportation, and community gathering places. Demographic data like diabetes
prevalence or census results are typically gathered through secondary data sources rather than direct
observation. Individual medical histories are private and not observable during a community-wide
survey. This method provides a quick overview of the environmental factors affecting the health of the
population.
3. An occupational health nurse is conducting hearing screenings for employees at a local factory. This
activity is categorized as which level of prevention?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Environmental prevention
Ans: A
Explanation: Secondary prevention emphasizes early detection and diagnosis of health problems to limit
future disability. Hearing screenings allow the nurse to identify early signs of hearing loss among
workers exposed to high noise levels. This differs from primary prevention, which would involve
providing earplugs to prevent damage in the first place. Tertiary prevention would involve rehabilitation
for a worker who has already suffered significant hearing loss. Regular screenings are essential for
maintaining a safe and healthy workforce in industrial settings.
4. In epidemiology, the ‘Epidemiological Triangle’ consists of which three components?
A. Nurse, Patient, Environment
, B. Pathogen, Treatment, Outcome
C. Agent, Host, Environment
D. Incidence, Prevalence, Risk
Ans: C
Explanation: The epidemiological triangle is a traditional model that explains the development of
infectious diseases. The agent is the factor that causes the disease, while the host is the living being
affected by the agent. The environment includes the physical, social, and economic factors that influence
the interaction between the host and agent. Changes in any of these three components can lead to an
increase or decrease in disease frequency. Understanding this relationship helps community nurses
develop targeted interventions for disease control.
5. A nurse is reviewing the prevalence rate of hypertension in a specific county. How is the prevalence rate
defined?
A. The number of new cases of a disease during a specific time period
B. The ratio of deaths to the total number of cases of a disease
C. The number of deaths resulting from a specific disease
D. The total number of existing cases in the population at a specific point in time
Ans: D
Explanation: Prevalence rates reflect the total number of people in a population who have a specific
disease at a given time. This includes both newly diagnosed cases and existing cases that have not yet
resolved or resulted in death. In contrast, incidence rates only measure the number of new cases that
develop over a specified period. Prevalence is useful for understanding the overall burden of chronic
