Judgment, NGN & NCLEX-Style Practice Questions with Detailed
Rationales
Question 1: A community health nurse is preparing to implement a
new health promotion program in an underserved neighborhood.
Which action should the nurse take first according to the nursing
process?
A. Administer immunizations to high-risk populations
B. Conduct a comprehensive community needs assessment
C. Distribute health education pamphlets door-to-door
D. Evaluate the program's effectiveness at six months
CORRECT ANSWER: B. Conduct a comprehensive community
needs assessment
Rationale: The nursing process always begins with assessment. A
community needs assessment identifies the specific health problems,
available resources, and barriers unique to the population before any
interventions are planned. Implementing programs before assessment risks
misallocating resources and failing to address actual community priorities.
Question 2: A community health nurse is analyzing the spread of
an infectious disease using the epidemiological triangle. Which
component represents the susceptible human or population?
A. Agent
B. Environment
C. Host
D. Vector
CORRECT ANSWER: C. Host
Rationale: The epidemiological triangle consists of agent, host, and
environment. The host is the organism (human or animal) that harbors the
,disease. Host factors include age, sex, genetics, immune status, and
behavioral characteristics that influence susceptibility to the agent.
Question 3: A public health nurse is addressing social determinants
of health in a low-income community. Which factor should the
nurse identify as having the greatest impact on health outcomes?
A. Individual dietary choices
B. Access to affordable healthcare services
C. Personal hygiene practices
D. Frequency of exercise routines
CORRECT ANSWER: B. Access to affordable healthcare services
Rationale: Social determinants of health are conditions in the environments
where people are born, live, learn, work, and play. Access to healthcare is a
critical social determinant that directly influences health outcomes by
determining whether individuals can receive preventive services, manage
chronic conditions, and seek timely treatment.
Question 4: A community health nurse is conducting a home visit
for an elderly client who lives alone. Which observation should
prompt the nurse to recommend a home safety evaluation?
A. The client has a pet cat
B. The client uses a cane for ambulation
C. The client has loose area rugs in the hallway
D. The client reads the newspaper daily
CORRECT ANSWER: C. The client has loose area rugs in the
hallway
Rationale: Loose area rugs are a significant fall hazard, particularly for
elderly clients who may have decreased balance, vision, or mobility. Falls
are a leading cause of injury-related morbidity and mortality in older adults,
making environmental modification a priority intervention.
Question 5: A nurse is developing a disaster preparedness plan for
a community at risk for flooding. Which information is most
essential to include in the plan?
A. Locations of public swimming pools
B. Inventory of community recreational facilities
,C. Identification of vulnerable populations and evacuation routes
D. Schedule of routine health screening clinics
CORRECT ANSWER: C. Identification of vulnerable populations and
evacuation routes
Rationale: Effective disaster planning requires identifying populations at
greatest risk (elderly, disabled, non-English speaking, those without
transportation) and establishing clear evacuation routes. This information
ensures that resources are directed to those who need them most during an
emergency.
Question 6: A nurse is educating a community group about primary
prevention. Which activity is the best example of primary
prevention?
A. Providing hepatitis A vaccination to restaurant workers
B. Screening for hypertension at a health fair
C. Administering antibiotics to a client with an infection
D. Referring a stroke client to physical therapy
CORRECT ANSWER: A. Providing hepatitis A vaccination to
restaurant workers
Rationale: Primary prevention aims to prevent disease or injury before it
occurs. Immunization is a classic example of primary prevention. Screening
(secondary prevention) detects disease early, while treatment and
rehabilitation (tertiary prevention) address existing conditions.
Question 7: A community health nurse is working with a
population of migrant farmworkers who lack health insurance.
Which action best addresses the root cause of their healthcare
access barriers?
A. Providing free blood pressure screenings weekly
B. Distributing educational materials about diabetes
C. Collaborating with providers to establish a mobile clinic
D. Recommending the workers find employment in urban areas
CORRECT ANSWER: C. Collaborating with providers to establish a
mobile clinic
Rationale: A mobile clinic directly addresses the structural barrier of
healthcare access for migrant workers who face geographic isolation, lack
, of transportation, and absence of insurance. While screenings and
education are valuable, they do not solve the underlying problem of no
available source of care.
Question 8: A nurse is teaching a group about health disparities.
Which population is at greatest risk for experiencing barriers to
healthcare access?
A. Urban professionals with employer-sponsored insurance
B. Rural residents with limited transportation options
C. Suburban families with annual preventive checkups
D. College students with campus health services
CORRECT ANSWER: B. Rural residents with limited transportation
options
Rationale: Rural populations often face significant barriers including
geographic isolation, fewer healthcare providers, lack of public
transportation, and higher rates of uninsurance. These factors combine to
create substantial disparities in healthcare access and health outcomes
compared to urban and suburban populations.
Question 9: A community health nurse is planning a health fair for
adolescents. Which health topic should be prioritized based on
leading causes of adolescent morbidity and mortality?
A. Colorectal cancer screening
B. Blood pressure management
C. Safety belt use and injury prevention
D. Fall prevention strategies
CORRECT ANSWER: C. Safety belt use and injury prevention
Rationale: Unintentional injuries, particularly motor vehicle crashes, are the
leading cause of death among adolescents. Safety belt use and injury
prevention education directly address this leading cause of morbidity and
mortality in this age group. Colorectal cancer screening and fall prevention
are priorities for older adults.
Question 10: A nurse is investigating a foodborne illness outbreak
at a community event. Which action is most critical for controlling
the outbreak?
