SECTION ONE: QUESTIONS 1 – 100
,1. A community health nurse is using the epidemiological triangle to understand an outbreak of a novel
respiratory virus. Which component of the triangle would include the virus's ability to survive on surfaces and its
mode of transmission?
A. Host
B. Agent
C. Environment
D. Vector
🟢 B. Agent
🔴 Explanation: The agent is the external factor that causes disease, including its characteristics like infectivity,
pathogenicity, and survival outside the host. The environment encompasses external factors like climate and
sanitation, while the host refers to the person or organism affected.
2. A public health department is implementing a policy to reduce sodium intake in the community. This is an
example of which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention
D. Primordial prevention
🟢 A. Primary prevention
🔴 Explanation: Primary prevention aims to prevent disease before it occurs by altering risk factors or exposures.
Reducing sodium intake in the general population is a primary prevention strategy to prevent hypertension.
Secondary prevention involves early detection, and tertiary prevention focuses on managing existing disease.
,3. During a community health assessment, which data source provides the most direct information about the
health status and behaviors of a specific local population?
A. National Vital Statistics Reports
B. Behavioral Risk Factor Surveillance System (BRFSS) data
C. Hospital discharge records
D. U.S. Census Bureau data
🟢 B. Behavioral Risk Factor Surveillance System (BRFSS) data
🔴 Explanation: The BRFSS is a state-based system of health surveys that collects information on health risk
behaviors, chronic health conditions, and use of preventive services from a representative sample of the population.
While other sources provide valuable data, BRFSS offers direct, self-reported behavioral and health status data at the
state and local level.
4. A community organizer is facilitating a coalition to address childhood obesity. Which of the following is the
FIRST step in the community organizing process?
A. Identifying key leaders and stakeholders
B. Defining the community's health problem
C. Recognizing the issue and mobilizing the community
D. Developing an action plan
🟢 C. Recognizing the issue and mobilizing the community
🔴 Explanation: The initial phase of community organizing involves recognizing the issue and generating enough
interest and concern to mobilize the community for action. This precedes identifying leaders, defining the problem
more formally, and developing a plan.
, 5. According to the Health Belief Model, a person's decision to get a flu vaccine is MOST influenced by their
perception of:
A. Their social network's opinion
B. The cost of the vaccine
C. Their susceptibility to the flu and the severity of the illness
D. The convenience of the vaccination clinic location
🟢 C. Their susceptibility to the flu and the severity of the illness
🔴 Explanation: The Health Belief Model posits that perceived susceptibility and perceived severity are key drivers of
health behavior. An individual must believe they are at risk and that the illness is serious to be motivated to take
action, such as getting vaccinated.
6. A city is experiencing a high rate of lead poisoning in children. This is MOST directly a failure of which public
health core function?
A. Assurance
B. Policy Development
C. Assessment
D. Prevention
🟢 A. Assurance
🔴 Explanation: Assurance is the public health core function that involves ensuring that essential health services are
available and accessible to everyone. A high rate of lead poisoning indicates a failure to adequately enforce lead-
safe housing regulations, provide education, and ensure access to screening services, all of which fall under
assurance.
