NUR 426 Exam 2: Community Health Nursing Theory &
Application V1 - Arizona College Updated and Latest
Questions and Correct Answers with Rationale
1. Which activity is an example of primary prevention in community health nursing?
A. Performing scoliosis screenings at a middle school
B. Providing physical therapy for a stroke survivor
C. Monitoring blood glucose levels for a diabetic patient
D. Administering the influenza vaccine at a local clinic
Ans: D
Explanation: Primary prevention aims to prevent disease or injury before it ever occurs by avoiding
exposure to hazards. Administering vaccines is a quintessential primary prevention strategy as it builds
immunity to prevent illness. Scoliosis screening is secondary prevention, while rehabilitation and glucose
monitoring are tertiary prevention. Nurses prioritize these interventions to reduce the overall incidence
of disease within a population. Understanding these levels of prevention is critical for effective resource
allocation in community health.
2. A nurse is conducting a secondary prevention activity. Which of the following best describes this action?
A. Teaching a class on healthy cooking for heart health
B. Screening patients for hypertension at a health fair
C. Leading a support group for individuals with cancer
D. Providing wound care for a patient with a pressure ulcer
Ans: B
,Explanation: Secondary prevention focuses on early detection and prompt treatment of diseases in their
earliest stages. Screening for hypertension allows for early intervention before the condition leads to
severe complications. Teaching healthy cooking is primary prevention, whereas support groups and
wound care are tertiary. This level of prevention helps in reducing the prevalence of severe disease
manifestations. It is a vital component of public health nursing that targets individuals who may be at
risk.
3. What is the goal of tertiary prevention?
A. To prevent the initial onset of a disease
B. To reduce the impact of an ongoing illness or injury
C. To screen for asymptomatic diseases
D. To eliminate all risk factors in the environment
Ans: B
Explanation: Tertiary prevention focuses on managing long-term health problems to prevent further
deterioration and improve quality of life. By providing rehabilitation or chronic disease management,
nurses help patients reach their maximum potential level of functioning. Primary prevention seeks to
stop the disease before it starts, and secondary focuses on early diagnosis. These interventions are often
complex and require multidisciplinary coordination over an extended period. This stage is crucial for
reducing disability and preventing premature death in chronic conditions.
4. In the epidemiological triangle, which of the following represents the ‘agent’?
A. The bacteria that causes tuberculosis
B. A child who has not been vaccinated
C. A crowded living environment
, D. The climate of a specific geographical area
Ans: A
Explanation: The agent is the physical, chemical, or biological factor that must be present for a disease to
occur. In this scenario, the tuberculosis bacteria is the biological agent responsible for the illness. The
child represents the host, while the crowded environment and climate represent the environmental
factors. Community nurses use this triangle to understand how different factors interact to spread
disease. Balancing these three components is key to controlling outbreaks and improving community
health outcomes.
5. Which term describes the number of new cases of a disease in a population over a specific period?
A. Prevalence rate
B. Incidence rate
C. Mortality rate
D. Morbidity rate
Ans: B
Explanation: Incidence rate refers specifically to the occurrence of new cases within a defined
population during a set timeframe. It provides information about the risk of contracting a disease within
that community. Prevalence, on the other hand, includes both new and existing cases at a single point in
time. Mortality measures deaths, while morbidity measures the overall burden of illness. Monitoring
incidence helps public health officials track the effectiveness of primary prevention programs.
6. A nurse is calculating the prevalence of obesity in a community. What should the nurse include in the
calculation?
A. Only the new cases diagnosed this month
