1. A community health nurse is organizing a blood pressure screening at a local senior center. Which level of
prevention does this activity represent?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Quaternary prevention
Ans: A
Explanation: Secondary prevention involves early detection and screening of diseases to limit disability.
By checking blood pressures, the nurse identifies individuals at risk or in early stages of hypertension.
Primary prevention focuses on health promotion before disease occurs. Tertiary prevention aims to
rehabilitate those with existing disease. Screening programs are quintessential examples of secondary
intervention strategies in community settings.
2. In the epidemiological triangle, a nurse identifies contaminated water as the factor leading to a cholera
outbreak. Which component of the triangle does the water represent?
A. Agent
B. Host
C. Environment
D. Vector
Ans: C
,Explanation: The environment includes physical factors like water quality that influence the spread of
disease. In this scenario, the water serves as the medium through which the agent reaches the host. The
agent itself would be the Vibrio cholerae bacteria. The host is the human population affected by the
contaminated source. Understanding these interactions is vital for implementing effective community-
wide health interventions.
3. Following a major flood, a nurse works with city planners to restore the local clinic’s services. Which
phase of disaster management is being implemented?
A. Mitigation
B. Recovery
C. Response
D. Preparedness
Ans: B
Explanation: The recovery phase focuses on returning the community to a new state of normalcy.
Rebuilding infrastructure and restoring essential services like health clinics are primary goals during this
time. Mitigation involves long-term planning to reduce the impact of future disasters. Response occurs
immediately during the impact of the event itself. This stage requires extensive collaboration between
health officials and local government agencies.

of prevention?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
, D. Health maintenance

Explanation: Primary prevention aims to prevent the onset of disease through specific protections like
vaccines. By immunizing students, the nurse builds community immunity and prevents future outbreaks.

effective way to manage public health risks in school settings. Other examples include nutrition
counseling and health education programs.

performing?
A. Clinician
B. Case Manager

D. Health Educator
Ans: B

to have deep knowledge of community-based support systems. Effective case management reduces
fragmentation of care for vulnerable populations.
