70 Questions with Answers and Rationales
Question 1. A community health nurse is conducting a windshield survey of a
neighborhood. Which of the following observations would be most concerning
regarding environmental health hazards?
A. Well-maintained sidewalks with adequate lighting throughout the neighborhood
B. Several homes with peeling lead-based paint in a low-income area with young
children
C. A community garden with organized plots maintained by local residents
D. A newly constructed playground with rubberized safety surfacing
Correct
Answer B
Rationale:
Lead-based paint is a significant environmental health hazard, particularly in low-income
neighborhoods where older housing stock is common. Young children are especially
vulnerable to lead poisoning because they engage in hand-to-mouth behavior and their
developing nervous systems are highly susceptible to lead toxicity. Lead exposure can
cause irreversible cognitive deficits, behavioral disorders, and developmental delays. The
nurse should prioritize reporting this finding to the appropriate local health department
for lead abatement programs and screening of at-risk children. Well-maintained
sidewalks, community gardens, and safe playgrounds are positive community assets that
promote health and well-being.
Question 2. The nurse is planning a health promotion program for a rural
community with limited access to healthcare services. Which of the following
strategies would be most effective in reaching this population?
, A. Distributing flyers at the nearest urban hospital emergency department
B. Establishing mobile health clinics that visit the community on a regular schedule
C. Creating a social media campaign targeting young adults in the area
D. Hosting a health fair at a location 30 miles from the community center
Correct
Answer B
Rationale:
Mobile health clinics are the most effective strategy for reaching rural populations with
limited healthcare access because they bring services directly to the community,
removing transportation barriers that are often the primary obstacle to care in rural
areas. Rural residents frequently travel long distances to reach healthcare facilities, and
many do not have reliable personal transportation. Mobile clinics can provide preventive
services, chronic disease management, health education, and referrals. Flyers at urban
hospitals miss the target population entirely, social media campaigns may not reach
older or less technologically connected residents, and a health fair 30 miles away
continues to present the same access barriers the program aims to overcome.
Question 3. A public health nurse is investigating an outbreak of hepatitis A in a
community. Which of the following actions should the nurse take first?
A. Administer hepatitis A vaccine to all community members immediately
,ATI RN Community Health Fundamental Proctored Exam 2026 With NGN 70 Questions
B. Identify the source of the outbreak by conducting a detailed epidemiological
investigation
C. Isolate all individuals who have been diagnosed with hepatitis A
D. Issue a public health advisory through local media outlets
Correct
Answer B
Rationale:
The first priority in investigating any disease outbreak is to identify the source through
systematic epidemiological investigation. This involves confirming the diagnosis,
defining the case criteria, collecting data on affected individuals, and analyzing the
common exposures to identify the point source. Hepatitis A is typically transmitted
through the fecal-oral route, often via contaminated food or water. Without identifying
the source, any intervention may be misdirected and ineffective. While vaccination,
isolation of cases, and public communication are all important components of an
outbreak response, they must be guided by the epidemiological findings to be effective.
The nurse must first gather and analyze data before implementing targeted
interventions.
Question 4. When using the epidemiological triad to analyze a health problem,
which component refers to the susceptibility of a host to a disease?
A. Agent
B. Environment
C. Hostsusceptibility
D. Vector
Correct
Answer C
Rationale:
The epidemiological triad consists of three components: agent, host, and environment.
Host susceptibility refers to the characteristics of an individual or population that
increase vulnerability to a particular disease or condition. These characteristics include
genetic predisposition, immune status, age, sex, nutritional status, pre-existing
conditions, and behavioral factors. The agent is the infectious organism or
environmental factor that causes disease. The environment refers to external factors
Page 2
, ATI RN Community Health Fundamental Proctored Exam 2026 With NGN 70 Questions
that influence the agent-host interaction, such as sanitation, climate, and socioeconomic
conditions. A vector is an intermediate carrier that transmits the agent from one host to
another, such as a mosquito in malaria transmission. Understanding host susceptibility
is essential for identifying at-risk populations and targeting preventive interventions
appropriately.
Question 5. A community health nurse is working with a population that has a
high incidence of type 2 diabetes mellitus. Which of the following interventions
represents secondary prevention?
A. Providing nutrition education on low-glycemic diet to community groups
B. Organizingcommunity-wide exercise programs to reduce obesity rates
C. Conducting diabetes screening clinics at local community centers
D. Developing a support group for individuals with diabetes complications
Correct
Answer C
Rationale:
Secondary prevention focuses on early detection and prompt treatment of disease in its
asymptomatic or early symptomatic stages to halt or slow disease progression. Diabetes
screening clinics represent secondary prevention because they aim to identify individuals
with undiagnosed diabetes or prediabetes so that treatment can be initiated before
complications develop. Providing nutrition education and organizing exercise programs
are examples of primary prevention, which aims to prevent disease from occurring in the
first place by modifying risk factors. Developing a support group for individuals with
complications represents tertiary prevention, which focuses on managing established
disease and preventing further deterioration. The American Diabetes Association
recommends screening for type 2 diabetes in adults aged 35 years or older, regardless
of weight, and in younger adults who are overweight or obese with additional risk
factors.
