1. A nurse is planning a community-wide educational program on the importance of annual
influenza vaccinations. Which level of prevention is the nurse addressing?
A. Secondary Prevention
B. Primary Prevention
C. Tertiary Prevention
D. Quaternary Prevention
Correct Answer: B
Explanation: Primary prevention focuses on health promotion and the prevention of the
onset of disease. Immunizations are a classic example of primary prevention as they aim to
prevent the occurrence of illness in the first place. The nurse is targeting the entire
community to maintain health and prevent flu outbreaks.
2. Which of the following are considered Social Determinants of Health (SDOH) that impact
community health outcomes? (Select all that apply)
A. Economic Stability
B. Education Access and Quality
C. Neighborhood and Built Environment
,D. Genetic Predisposition
E. Social and Community Context
F. Health Care Access and Quality
Correct Answer: A, B, C, E, F
Explanation: Social Determinants of Health are the conditions in the environments where
people are born, live, learn, work, play, worship, and age. Genetic predisposition is a
biological factor, not a social determinant. Addressing these five domains is critical for
achieving health equity in population health management.
3. The epidemiological triangle consists of which three components?
A. Agent, Host, and Environment
B. Doctor, Patient, and Hospital
C. Risk, Resilience, and Outcome
D. Bacteria, Virus, and Parasite
Correct Answer: A
Explanation: The epidemiological triangle is a model used to explain the etiology of
infectious diseases. It involves the interaction of an agent, a host, and the environment.
Understanding these relationships allows community health nurses to identify points of
intervention to break the chain of transmission.
, 4. Which action by the community health nurse represents secondary prevention?
A. Teaching a patient with diabetes about foot care
B. Performing blood pressure screenings at a local health fair
C. Administering a hepatitis B vaccine to a newborn
D. Providing rehabilitation services to a patient after a stroke
Correct Answer: B
Explanation: Secondary prevention involves early detection and intervention to limit the
severity of a disease. Screenings, such as blood pressure checks or mammograms, are
hallmark examples of secondary prevention. This level of care aims to identify
asymptomatic individuals who have risk factors or early stages of a condition.
5. A nurse is working with a patient who has chronic obstructive pulmonary disease (COPD) to
improve their quality of life and prevent further complications. This is an example of:
A. Primary Prevention
B. Tertiary Prevention
C. Secondary Prevention
D. Primordial Prevention
Correct Answer: B
