ATI RN COMMUNITY HEALTH RETAKE EXAM
2026 NGN-STYLE COMPLETE (110) CURRENT
TESTING QUESTIONS AND CORRECT
ANSWERS WITH DETAILED RATIONALES.
COMMUNITY HEALTH
Prepare for the ATI RN Community Health Retake Exam | NGN-Style with
practice questions covering Community health nursing roles, population
health, community assessment, epidemiology, health promotion, disease
prevention, disaster preparedness, environmental health, and evidence-
based nursing interventions. Designed to improve clinical judgment skills
and boost confidence in addressing the health needs of individuals,
families, and communities. Suitable for RN nursing students preparing for
ATI Community Health assessments and NGN-based nursing exams.
MULTIPLE CHOICE.
1. A community health nurse is using the epidemiological triangle to
investigate an outbreak of hepatitis A. Which component represents
the “host”?
A. Contaminated food
B. A susceptible person
C. Warm, humid environment
D. Poor sanitation
Correct answer: B. A susceptible person
Rationale: The epidemiological triangle consists of agent, host,
and environment. The host is the human or animal that can get
, Page 2 of 60
the disease. Contaminated food is the agent; warm, humid
environment and poor sanitation are environmental factors.
2. A nurse is planning a secondary prevention activity for
cardiovascular disease. Which intervention should the nurse
include?
A. Teaching healthy eating habits to schoolchildren
B. Screening adults for high blood pressure at a community health
fair
C. Providing cardiac rehabilitation after a myocardial infarction
D. Administering antihypertensive medications to a client with
stroke
Correct answer: B. Screening adults for high blood pressure at a
community health fair
Rationale: Secondary prevention focuses on early detection and
treatment of disease. Screening for hypertension identifies
disease before symptoms appear. Primary prevention prevents
disease (A). Tertiary prevention reduces disability after disease
(C, D).
3. A community health nurse is conducting a windshield survey.
Which finding indicates a need for further assessment of potential
environmental health risks?
A. Several new playgrounds in a residential area
B. A chemical plant located adjacent to a low-income housing
complex
, Page 3 of 60
C. A public library with wheelchair accessibility
D. A weekly farmers’ market in the town square
Correct answer: B. A chemical plant located adjacent to a
low-income housing complex
Rationale: Proximity of industrial facilities to residential areas
raises concerns about air and water pollution, increased asthma
rates, and environmental justice issues. The nurse should
assess potential exposure risks.
4. A nurse is triaging victims after a tornado using a disaster triage
tag system. Which victim should receive the highest priority
(immediate care)?
A. A victim with a minor laceration who is able to walk
B. A victim with severe head trauma and agonal breathing
C. A victim with a fractured femur, strong radial pulse, and alert
mental status
D. A victim with partial-thickness burns covering 15% of total body
surface area who is able to follow commands
Correct answer: D. A victim with partial-thickness burns
covering 15% of total body surface area who is able to follow
commands
Rationale: In disaster triage, immediate (red tag) victims have
life-threatening injuries but high chance of survival with
treatment. Option D (burns 15%, able to follow commands) is
urgent but not expectant. Option A is minor (green tag). Option B
is expectant/black tag (agonal breathing, severe head trauma
, Page 4 of 60
unlikely to survive). Option C is delayed (yellow tag) – stable but
needs care within hours.
5. A community health nurse is providing education about lead
poisoning prevention. Which statement by a parent indicates
understanding?
A. “I will use hot tap water to prepare infant formula.”
B. “I will wash my child’s hands frequently and use a wet mop to
clean floors.”
C. “I will sand peeling paint in my older home before repainting.”
D. “I will give my child an iron-rich diet only after lead levels are
elevated.”
Correct answer: B. “I will wash my child’s hands frequently and
use a wet mop to clean floors.”
Rationale: Hand washing and wet cleaning reduce lead dust
exposure. Hot tap water leaches more lead from pipes; cold
water should be used. Sanding old paint creates lead dust.
Iron-rich diet helps prevent absorption but should be given
before, not after, elevation.
6. A nurse is conducting a home visit for a client with heart failure.
Which action demonstrates the nurse’s role in case management?
A. Coordinating a referral to a home health aide for bathing
assistance
B. Teaching the client about low-sodium diet options
C. Assessing the client’s lung sounds and peripheral edema
D. Documenting the client’s blood pressure in the medical record
