SECTION 1: FOUNDATIONS OF COMMUNITY AND PUBLIC HEALTH NURSING
🟢 Question 1
A community health nurse is implementing a population-focused practice. Which of the following
actions best demonstrates this approach?
A. Providing direct wound care to a client in a home health setting
B. Conducting a health education session for a group of pregnant teenagers
C. Analyzing data to identify trends in obesity rates among school-aged children in the district
D. Administering immunizations to individual clients at a health fair
🔴🔴 Correct Answer: C
Rationale: Population-focused practice emphasizes assessing and intervening at the community or
population level rather than focusing on individuals. Analyzing data to identify trends in obesity rates
among school-aged children represents a population-focused approach because it examines health
patterns across a group and informs community-level interventions. Option A represents individual-
focused care. Option B, while delivered to a group, targets a specific subset without the broader
epidemiological analysis characteristic of population health. Option D is an individual-level intervention.
🟢 Question 2
A public health nurse is applying the core functions of public health as defined by the Institute of
Medicine (IOM). Which activity represents the core function of policy development?
A. Collecting data on the incidence of tuberculosis in the community
B. Ensuring that all community members have access to clean drinking water
C. Advocating for legislation to require smoke-free environments in public places
D. Evaluating the effectiveness of a diabetes management program
🔴🔴 Correct Answer: C
Rationale: The three core functions of public health are assessment, policy development, and assurance.
Policy development involves advocating for and developing policies that support the health of the
population. Advocating for smoke-free legislation is a clear example of policy development. Option A
represents assessment (data collection). Option B is an assurance function. Option D is evaluation, which
falls under assurance.
🟢 Question 3
A community health nurse is utilizing the epidemiological triad to investigate an outbreak of
salmonellosis. Which component of the triad would be the primary focus of interventions aimed at
pasteurizing milk and properly cooking eggs?
A. Host
,B. Agent
C. Environment
D. Vector
🔴🔴 Correct Answer: B
Rationale: The epidemiological triangle consists of agent, host, and environment. The agent is the
causative factor. For salmonellosis, the Salmonella bacterium is the agent. Pasteurization and proper
cooking are interventions that target the agent itself by eliminating or reducing its presence in food
sources. The host would be the person, and the environment would be the conditions allowing
transmission.
🟢 Question 4
A public health nurse is explaining the concept of "population health" to new staff. Which statement
accurately describes population health?
A. Treating individual patients with chronic diseases
B. Focusing on the health outcomes of a group of individuals, including distribution of outcomes
C. Providing acute care services to communities
D. Managing hospital admissions and discharges
🔴🔴 Correct Answer: B
Rationale: Population health focuses on the health outcomes of a group, including the distribution of
those outcomes within the group. It goes beyond individual care to consider the broader determinants
of health that affect entire populations. Options A, C, and D describe individual-level clinical care or
administrative tasks, not population health.
🟢 Question 5
A nurse is working with a case manager for a client who participates in a health maintenance
organization (HMO). The nurse should identify that an HMO provides which of the following payment
structures?
A. The client pays the insurer a percentage of the total cost for each service
B. The provider is paid a fixed sum for the client on a monthly or yearly basis
C. The client participates in a fee-for-service health care insurance program
D. The provider bills the client directly a predetermined percentage for services
🔴🔴 Correct Answer: B
Rationale: HMOs use a capitated payment model where providers receive a fixed monthly or yearly
payment per enrolled client, regardless of services rendered. This structure incentivizes preventive care
and cost-effective management. Option A describes a coinsurance model. Option C describes fee-for-
service. Option D describes a direct billing arrangement.
🟢 Question 6
A parish nurse is planning activities for a faith-based community. Which of the following activities should
the nurse include?
A. Provide case management services
B. Offer primary care to uninsured members
C. Teach stress management strategies
D. Change negative pressure wound therapy dressings
, 🔴🔴 Correct Answer: C
Rationale: Parish nurses focus on health promotion and wellness within faith communities. Teaching
stress management aligns with the holistic, health-promotion focus of parish nursing. Case
management, primary care provision, and wound care are outside the typical scope or setting of this
role.
🟢 Question 7
A community health nurse is working with a migrant population. The nurse should recognize which of
the following interventions is necessary to provide care to this population?
A. Requiring clients to show proof of citizenship before receiving care
B. Providing services at locations and times that are accessible to the population
C. Limiting services to emergency care only
D. Focusing on individual treatment rather than population-level interventions
🔴🔴 Correct Answer: B
Rationale: Migrant populations often face barriers to healthcare access, including mobility, language,
and fear of deportation. Providing services at accessible locations and times (e.g., evenings, weekends,
community centers) is essential to reach this population. Requiring proof of citizenship is a barrier.
Limiting services to emergency care is unethical and ineffective. Focusing only on individual treatment
misses the population-level needs.
🟢 Question 8
A nurse is conducting a community health assessment. What is the primary purpose of this assessment?
A. To identify individual health problems for targeted interventions
B. To gather data on the health status, needs, and resources of a community
C. To evaluate the performance of individual healthcare providers
D. To determine the budget for hospital services
🔴🔴 Correct Answer: B
Rationale: The primary purpose of a community health assessment is to gather comprehensive data on
the health status, needs, and resources of a defined community. This information is used to identify
priority health issues and plan population-focused interventions. It is not focused on individual problems
or provider performance.
🟢 Question 9
A community-oriented nurse is planning care. What is the primary goal of community-oriented nursing?
A. Providing direct illness care to individuals and families
B. Health promotion and disease prevention for populations
C. Managing acute care in hospital settings
D. Focusing on reimbursement for services
🔴🔴 Correct Answer: B
Rationale: Community-oriented nursing emphasizes health promotion, disease prevention, and
population health. Its goal is to improve the health of the community as a whole. Community-based
nursing, in contrast, provides direct illness care to individuals and families in community settings.
Hospital-based care is not the focus of community-oriented nursing.
