2026 ATI RN Community Health
Practice Exam Practice Questions with
Answers and Detailed Rationales
Question 1
A community health nurse is planning a primary prevention
program for adolescents in a community with increasing rates
of sexually transmitted infections (STIs). Which intervention
should the nurse prioritize?
A. Providing antibiotic treatment to adolescents diagnosed
with chlamydia
B. Conducting contact tracing for adolescents with confirmed
STIs
C. Providing comprehensive sexual health education and
promoting safer-sex practices
D. Screening adolescents who report symptoms of pelvic
inflammatory disease
Rationale: Primary prevention aims to prevent disease before
it occurs. Comprehensive sexual health education and safer-
sex practices reduce STI transmission risk. Antibiotic
treatment and contact tracing are secondary or tertiary
prevention activities, while screening is secondary prevention.
Question 2
,A nurse is assessing a community's risk for an outbreak of
foodborne illness. Which finding requires the most
immediate intervention?
A. Several residents report mild nausea after eating at a
community event
B. A restaurant has received three complaints about food
quality
C. A local grocery store reports an increase in sales of
refrigerated foods
D. Multiple residents develop vomiting and diarrhoea after
eating food from the same event
Rationale: A cluster of similar gastrointestinal symptoms
among people who consumed food from the same source
suggests a possible common-source outbreak. Prompt
investigation and reporting are essential to identify the
source, prevent additional cases, and initiate appropriate
public health measures.
Question 3
A community health nurse is evaluating a tuberculosis (TB)
control program. Which activity represents secondary
prevention?
A. Administering directly observed therapy to a client with
active TB
B. Screening high-risk individuals with tuberculosis testing
C. Educating the public about respiratory hygiene
D. Improving ventilation in homeless shelters
,Rationale: Secondary prevention focuses on early detection
through screening. Directly observed therapy is part of
treatment and disease control, while education and
environmental interventions primarily prevent transmission
and represent primary prevention strategies.
Question 4
A nurse is conducting a windshield survey in an urban
community. Which observation is most important when
evaluating environmental health?
A. The number of residents attending religious services
B. The availability of recreational activities
C. The presence of abandoned buildings with accumulated
garbage and standing water
D. The number of residents using public transportation
Rationale: Abandoned buildings, garbage, and standing
water can contribute to rodent infestations, insect-borne
diseases, injury risks, and other environmental hazards. These
findings require attention during community assessment.
Question 5
A public health nurse is preparing a disaster response plan for
a community located near a major river. Which intervention
demonstrates mitigation?
A. Establishing shelters after a flood occurs
B. Providing emergency food during a flood
, C. Supporting flood-control infrastructure and enforcing
building restrictions in flood-prone areas
D. Conducting triage immediately after floodwaters recede
Rationale: Mitigation involves actions taken before a disaster
to reduce its potential impact. Flood-control measures and
restrictions on construction in high-risk areas decrease future
disaster-related harm.
Question 6
A nurse is caring for a client with suspected measles in a
community clinic. Which action is the priority?
A. Place the client in a room with other clients who have
respiratory symptoms
B. Obtain a routine annual vaccination history
C. Provide antibiotics immediately
D. Implement appropriate airborne precautions and notify
public health authorities
Rationale: Measles is highly contagious and transmitted
through airborne particles. Immediate isolation and public
health notification are critical to prevent further transmission
and initiate contact investigation.
Question 7
A community health nurse is teaching residents about
reducing cardiovascular disease risk. Which recommendation
represents primary prevention?
