1. A community health nurse is conducting a vision screening for a group of kindergarten
students. Which level of prevention is being implemented?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Quaternary prevention
Correct Answer: A
Explanation: Secondary prevention focuses on early detection and screening to limit the
impact of a disease or condition. Vision screening identifies potential issues early so that
interventions can occur before the condition worsens. This level of care differs from
primary prevention, which focuses on preventing the condition from occurring in the first
place.
2. Which core function of public health involves the systematic collection, assembly, and
analysis of data regarding the health of a population?
A. Assessment
B. Assurance
,C. Policy Development
D. Management
Correct Answer: A
Explanation: Assessment is the process of collecting and analyzing information about
health conditions and risks within a community. It serves as the foundation for identifying
needs and setting priorities for intervention. The other core functions, Policy Development
and Assurance, build upon the data gathered during the assessment phase.
3. A nurse is investigating an outbreak of foodborne illness in a local restaurant. According to
the epidemiological triangle, the contaminated food represents which component?
A. The Host
B. The Agent
C. The Environment
D. The Vector
Correct Answer: B
Explanation: The Agent is the factor that must be present for a disease to occur, such as
bacteria, viruses, or chemical contaminants in food. In the epidemiological triangle, the
Host is the person susceptible to the disease, and the Environment is the external factors
that allow the agent to reach the host. Understanding these relationships is crucial for
implementing effective control measures during an outbreak.
, 4. A nurse is teaching a community group about the benefits of physical activity to prevent
heart disease. This is an example of:
A. Health restoration
B. Secondary prevention
C. Tertiary prevention
D. Primary prevention
Correct Answer: D
Explanation: Primary prevention refers to interventions that occur before a disease
process has begun to prevent its onset. Educating individuals on lifestyle modifications like
exercise aims to reduce risk factors and promote general wellness. This differs from
secondary prevention, which involves screening, and tertiary prevention, which involves
rehabilitation.
5. A community health nurse is using the I-PREPARE mnemonic to conduct an environmental
health assessment. What does the ‘E’ in PREPARE stand for?
A. Existing conditions
B. Environmental factors
C. Endocrine disruptors
D. Employment
