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 blood pressure screenings at a health fair
B. Teaching a patient how to use a nebulizer after a diagnosis
C. Leading a support group for individuals with diabetes
D. Providing immunizations to children at a local clinic
Ans: D
Explanation: Primary prevention focuses on preventing the initial occurrence of disease or injury.
Providing immunizations is a classic example because it builds immunity before exposure happens. This
level of intervention aims to reduce the incidence of disease in a population. It differs from secondary
prevention which involves early detection like screenings. Understanding these levels is essential for
effective community health nursing practice.
2. In the epidemiological triangle, which factor represents the person or animal that harbors the disease?
A. The environment
B. The agent
C. The vector
D. The host
Ans: D
Explanation: The host is the living being that is affected by the agent in the epidemiological triangle.
Factors such as age, gender, and genetics can influence a host’s susceptibility to illness. This triangle
,helps nurses understand the relationship between different elements of disease transmission. The
environment refers to external factors that facilitate the spread of the agent. Identifying the host allows
for targeted interventions to improve individual or group resistance.
3. What is the primary goal of a windshield survey in community assessment?
A. To interview local government officials about funding
B. To diagnose individual patients within their own homes
C. To provide an objective overview of the community’s environment
D. To review the medical records of all community residents
Ans: C
Explanation: A windshield survey is an informal tool used to observe the community while driving or
walking through it. It provides a visual overview of the physical environment, housing, and available
resources. This method helps the nurse identify potential health risks and community strengths quickly.
It is often the first step in a comprehensive community health assessment. This objective data collection
is vital for planning future community-based health programs.
4. A community health nurse is conducting a vision screening for kindergarteners. This is an example of
which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Quaternary prevention
Ans: B
, Explanation: Secondary prevention involves activities aimed at early detection and treatment of disease
to limit severity. Vision screenings are designed to identify issues early so that corrective measures can
be taken. This prevents the progression of vision loss or learning difficulties in children. Unlike primary
prevention, the focus here is on identifying a condition that may already exist. It is a critical component of
school nursing and public health programs.
5. Which of the following describes the ‘incidence rate’ in epidemiology?
A. The total number of existing cases in a population at a specific time
B. The proportion of the population that has recovered from an illness
C. The number of deaths resulting from a specific disease
D. The number of new cases of a disease in a population during a specific period
Ans: D
Explanation: The incidence rate specifically tracks new cases of a condition within a defined timeframe.
This metric helps nurses understand how quickly a disease is spreading in a community. In contrast,
prevalence includes both new and existing cases to show the total burden. Incidence is particularly useful
when studying acute outbreaks of infectious diseases. Accurate tracking of incidence is necessary for
evaluating the effectiveness of prevention strategies.
6. A nurse provides education on insulin administration to a client recently diagnosed with type 2 diabetes.
This is an example of:
A. Tertiary prevention
B. Secondary prevention
C. Primary prevention
D. Health promotion
