ATI RN Community Health Practice Exam | 1
,Section 1: Brief Introduction
This practice exam reviews community health nursing principles, epidemiology, prevention,
population health, environmental and occupational health, disaster management, communicable
disease control, care coordination, cultural safety, and public health ethics. Several questions use
NGN-style case scenarios that require prioritization, clinical judgment, and application of
population-focused nursing concepts.
Section 2: The Complete Practice Exam
Instructions: Select the best answer. Answers and detailed rationales are shown after each question
for study use. Follow local law, public health guidance, and agency policy in actual practice.
1. A public health nurse is assigned to a rural county with high rates of preventable hospitalization.
Which initial action best reflects the community-as-client framework?
A. begin by collecting population-level data and engaging stakeholders about community-
as-client assessment
B. start individual treatment plans before assessing population needs
C. use hospital discharge data alone to define the problem
D. implement a program selected by the nurse without community input
Answer: A. begin by collecting population-level data and engaging stakeholders about
community-as-client assessment Rationale: The community-as-client framework treats the
population, not only individual residents, as the unit of care. The nurse should combine quantitative and
qualitative assessment with community participation before selecting interventions.
2. Which epidemiologic measure is represented by new cases of measles among 10,000 residents
during one month?
A. prevalence
B. incidence
C. attack rate
D. case-fatality rate
Answer: B. incidence Rationale: Incidence measures new cases over time, whereas prevalence
measures all existing cases at a point or during a period. Attack rate is a proportion of an exposed
group that becomes ill during an outbreak; mortality and case-fatality describe deaths.
3. Which level of prevention is best represented by immunization of infants?
A. secondary prevention
B. tertiary prevention
C. primary prevention
D. health promotion
Answer: C. primary prevention Rationale: Primary prevention prevents disease, secondary
prevention detects disease early, and tertiary prevention limits disability or complications. The
intervention should be classified by its timing and purpose rather than by the setting alone.

, 4. A nurse encounters a positive tuberculosis screening result in a shelter resident. Which action has
the highest priority?
A. wait for confirmatory testing before using any precautions
B. tell the client to return to normal activities if afebrile
C. provide only routine health-promotion brochures
D. place the client in appropriate airborne precautions and arrange diagnostic evaluation
Answer: D. place the client in appropriate airborne precautions and arrange diagnostic
evaluation Rationale: Immediate infection-control actions reduce transmission while diagnostic
confirmation is pending. Reporting and isolation requirements vary by jurisdiction, but suspected high-
consequence or reportable conditions should be escalated promptly.
5. A community health nurse identifies a low-income client cannot afford a prescribed inhaler.
Which intervention best demonstrates advocacy and care coordination?
A. connect the client with medication assistance and an affordable prescriber/pharmacy
option
B. document the barrier without taking further action
C. tell the client to solve the barrier alone
D. refer the client only to a general website
Answer: A. connect the client with medication assistance and an affordable
prescriber/pharmacy option Rationale: Advocacy addresses structural and access barriers that affect
health outcomes. A coordinated plan should connect the client to a specific resource, verify feasibility,
and follow up on whether the barrier was resolved.
6. During a community assessment of a city block with vacant lots, standing water, and illegal
dumping, which method is most appropriate?
A. rely solely on national averages
B. conduct a windshield survey and map environmental risks with residents
C. collect only data that support the nurse’s initial hypothesis
D. avoid community members to preserve objectivity
Answer: B. conduct a windshield survey and map environmental risks with residents Rationale:
A valid community assessment triangulates existing data, direct observation, and community
perspectives. Partnership improves relevance and helps identify assets, risks, and culturally appropriate
priorities.
7. At a community picnic, 240 of 30 attendees develop vomiting within 24 hours. What is the attack
rate?
A. 80%
B. 12%
C. 800%
D. -114%
Answer: C. 800% Rationale: Attack rate is calculated as new cases among the exposed population
divided by the total exposed population, multiplied by 100. It helps investigators describe the extent of
illness in a defined outbreak group.
