1. A community health nurse is conducting an immunization clinic for infants and toddlers.
Which level of prevention is being implemented?
A. Tertiary prevention
B. Secondary prevention
C. Primary prevention
D. Quaternary prevention
Correct Answer: C
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease
or injury. Immunizations are a classic example as they build immunity before exposure to
pathogens. The nurse’s role in this setting is to reduce the incidence of vaccine-preventable
diseases in the population.
2. When performing a community assessment, the nurse conducts a windshield survey.
Which of the following components should be observed? (Select all that apply)
A. Condition of housing and public spaces
B. Availability and type of public transportation
,C. Analysis of local morbidity and mortality rates
D. Presence of grocery stores and food deserts
E. Geographic boundaries of the neighborhood
F. The ethnic and racial diversity of people on the street
Correct Answer: A, B, D, E, F
Explanation: A windshield survey is an informal survey where the nurse drives or walks
through a community to make visual observations. It allows the nurse to assess the
physical environment, social systems, and demographic characteristics of the community
members. Morbidity and mortality rates are quantitative data typically found through
secondary sources like health department records, not visual observation.
3. A public health nurse is investigating a sudden outbreak of a gastrointestinal illness. Which
component of the epidemiological triangle is the nurse focusing on when identifying the
contaminated water source?
A. Environment
B. Agent
C. Host
D. Vector
Correct Answer: A
,Explanation: The environment in the epidemiological triangle includes the physical, social,
or economic factors that allow the agent and host to interact. In this scenario, the
contaminated water source represents the physical environment that facilitates the
transmission of the pathogen. Identifying environmental factors is crucial for implementing
control measures to stop the outbreak.
4. The nurse is calculating the prevalence of Type 2 Diabetes in a specific county. Which of the
following best describes prevalence?
A. The number of new cases diagnosed within a specific time frame.
B. The total number of existing cases in the population at a specific point in time.
C. The rate at which a disease spreads from person to person.
D. The number of deaths caused by the disease in one year.
Correct Answer: B
Explanation: Prevalence refers to the total number of individuals in a population who have
a specific disease at a given time. It differs from incidence, which only tracks new cases.
This metric is essential for public health planning to determine the burden of chronic
diseases on a community’s resources.
5. Which of the following are considered social determinants of health according to the
Healthy People 2030 framework? (Select all that apply)
A. Economic Stability
B. Education Access and Quality
, C. Health Care Access and Quality
D. Neighborhood and Built Environment
E. Genetic Predisposition to disease
F. Social and Community Context
Correct Answer: A, B, C, D, F
Explanation: Social determinants of health (SDOH) are the conditions in the environments
where people are born, live, learn, work, play, worship, and age. Healthy People 2030
categorizes these into five domains including economic stability and education. Genetic
predisposition is a biological factor, not a social determinant, though it interacts with social
factors to influence health outcomes.
6. A nurse is using the I-PREPARE mnemonic to assess environmental exposure. What does
the ‘E’ in the mnemonic stand for?
A. Emergency preparedness
B. Environmental justice
C. Education and ethics
D. Environmental factors
Correct Answer: D
Explanation: The I-PREPARE mnemonic is a tool used by nurses to systematically evaluate
environmental health history. The second ‘E’ stands for Environmental factors, which
