Question 1: A community health nurse is employing the epidemiological triad
to understand the transmission of a novel zoonotic virus. Which component of
the triad would be the primary target for an intervention aimed at reducing the
vector population?
A. Host
B. Agent
C. Environment
D. Vector
CORRECT ANSWER: C. Environment
Rationale: The epidemiological triad consists of an agent, a host, and the environment.
The environment encompasses the external factors that allow for disease transmission,
including the physical, biological, and social conditions. A vector, such as a mosquito, is
part of the biological environment. Therefore, intervening to reduce the vector
population is an environmental intervention. The agent is the virus itself, and the host is
the infected organism.
Question 2: A nurse is using the Public Health Intervention Wheel to plan
interventions for a community with a high rate of obesity. Which activity
exemplifies the intervention of "Policy Development and Enforcement"?
A. Leading a community weight-loss support group.
B. Educating school children on healthy food choices.
C. Advocating for zoning laws that limit fast-food restaurants near schools.
D. Conducting BMI screenings at a local health fair.
CORRECT ANSWER: C. Advocating for zoning laws that limit fast-food
restaurants near schools.
Rationale: Policy Development and Enforcement involves activities that place health
issues on decision-makers' agendas, acquire a plan of resolution, and mandate action to
ensure compliance. Advocating for zoning laws is a direct action to create and enforce a
,policy that shapes the environment. Education is "Health Teaching," support groups are
"Collaboration" or "Counseling," and screenings are "Surveillance."
Question 3: A public health nurse is analyzing data to identify patterns of
disease occurrence. Which term describes the frequency of existing cases of a
disease in a population at a specific point in time?
A. Incidence
B. Prevalence
C. Mortality rate
D. Attack rate
CORRECT ANSWER: B. Prevalence
Rationale: Prevalence is a measure of disease burden, representing the total number of
existing cases (both new and old) in a defined population at a given time. Incidence
refers specifically to the number of new cases occurring over a period of time. Mortality
rate measures deaths, and attack rate is a type of incidence used in outbreak
investigations.
Question 4: A community health nurse is preparing to conduct a community
needs assessment. Which of the following is the PRIMARY purpose of this
process?
A. To secure funding for new health programs.
B. To identify the community's strengths, resources, and health challenges.
C. To comply with state and federal health regulations.
D. To evaluate the effectiveness of existing health interventions.
CORRECT ANSWER: B. To identify the community's strengths, resources, and
health challenges.
Rationale: The primary purpose of a community needs assessment is to gather
comprehensive data to identify the health status, needs, and assets of a community. This
information is used to prioritize health issues and plan appropriate interventions. While
it can support funding applications (A), its main goal is diagnosis. Evaluating
interventions (D) is a separate phase.
Question 5: A nurse is working in a migrant farmworker community and
notices a high incidence of pesticide-related illnesses. Using the
"Precautionary Principle," what action should the nurse take first?
A. Wait for conclusive scientific evidence before acting.
B. Distribute pamphlets on the safe use of pesticides.
,C. Take preventive action to reduce pesticide exposure despite scientific uncertainty.
D. Refer affected individuals to a specialist for treatment.
CORRECT ANSWER: C. Take preventive action to reduce pesticide exposure
despite scientific uncertainty.
Rationale: The Precautionary Principle states that in the face of a potential public
health threat, action should be taken to prevent harm even when full scientific certainty
is not yet established. The nurse should act to reduce exposure as a precautionary
measure to protect the community's health.
Question 6: A community health nurse is evaluating the quality of a local
health department's tuberculosis (TB) program. Which process would be the
most appropriate for the nurse to use?
A. Cost-benefit analysis
B. Quality assurance audit
C. Epidemiological investigation
D. Community focus group
CORRECT ANSWER: B. Quality assurance audit
Rationale: A quality assurance (QA) audit is a systematic process used to evaluate the
quality of services provided by a program against established standards and guidelines.
This is the most direct method for assessing program quality. A cost-benefit analysis
evaluates financial efficiency, while epidemiological investigation is for disease outbreak
or pattern analysis, and focus groups are for gathering qualitative data.
Question 7: A public health nurse is utilizing the "ecological model" to address
childhood obesity. Which intervention reflects the innermost level of this
model?
A. Changing the school lunch menu to include more fruits and vegetables.
B. Partnering with a local grocery chain to open a store in a "food desert."
C. Providing one-on-one counseling to a child about healthy food choices.
D. Advocating for a city-wide ban on trans-fats in restaurants.
CORRECT ANSWER: C. Providing one-on-one counseling to a child about
healthy food choices.
Rationale: The ecological model has multiple levels of influence: individual,
interpersonal, organizational, community, and public policy. The innermost level is the
individual (intrapersonal) level, which includes a person's knowledge, attitudes, and
behaviors. One-on-one counseling targets the child directly at this individual level.
, Question 8: During a community assessment, a nurse identifies that a high
percentage of residents are uninsured. According to the core functions of
public health, which function is the nurse fulfilling by identifying this issue?
A. Assurance
B. Policy Development
C. Assessment
D. Quality Improvement
CORRECT ANSWER: C. Assessment
Rationale: The core functions of public health are Assessment, Policy Development,
and Assurance. Assessment involves systematically collecting, analyzing, and making
available information on the health of a community, including health status, needs, and
resources. Identifying the number of uninsured residents is a component of this
assessment function.
Question 9: A nurse is teaching a client about the importance of the influenza
vaccine. The client states, "I never get the flu, so I don't need the shot." This
represents which level of the Health Belief Model?
A. Perceived susceptibility
B. Perceived severity
C. Perceived benefits
D. Cues to action
CORRECT ANSWER: A. Perceived susceptibility
Rationale: The Health Belief Model posits that an individual's likelihood of taking a
health action is based on several factors, including perceived susceptibility (belief about
the chances of getting a condition). The client's statement reflects a low perceived
susceptibility to the flu, believing they are not at risk.
Question 10: A community health nurse is implementing a primary prevention
strategy to reduce cardiovascular disease. Which activity is the nurse most
likely to perform?
A. Teaching a smoking cessation class to a group of smokers.
B. Screening adults for high blood pressure at a community fair.
C. Providing dietary counseling to a patient who had a myocardial infarction.
D. Conducting a blood pressure monitoring clinic for hypertensive patients.
CORRECT ANSWER: A. Teaching a smoking cessation class to a group of
smokers.
Rationale: Primary prevention aims to prevent disease or injury before it occurs. This is
achieved by reducing risk factors. Teaching smoking cessation is a classic primary
