Section 1: Epidemiology and Disease Prevention (Q1-Q15)
Q1: A public health nurse is analyzing data from a community outbreak of hepatitis A. The nurse identifies 45 new cases
among a population of 10,000 during the month of March. Which epidemiological measure is the nurse calculating?
A. Prevalence
B. Incidence [CORRECT]
C. Mortality rate
D. Attack rate
Correct Answer: B
Rationale: The nurse is calculating incidence, which measures the number of new cases of a disease in a population during a specific time
period. Prevalence measures all existing cases (new and pre-existing) at a given point in time, not just new ones. Mortality rate measures
deaths, and while attack rate is related to incidence in outbreaks, the scenario describes standard incidence calculation. ATI 2026/2027
guidelines emphasize distinguishing incidence from prevalence as a core epidemiologic competency for community health nurses.
Q2: A community health nurse is planning a program to reduce the incidence of type 2 diabetes in an at-risk population.
Which intervention represents primary prevention?
A. Conducting blood glucose screening at community health fairs
B. Providing education on nutrition and physical activity to prevent onset [CORRECT]
C. Establishing a support group for individuals diagnosed with diabetes
D. Initiating a disease management program for diabetic complications
Correct Answer: B
Rationale: Primary prevention aims to prevent disease before it occurs, and education on nutrition and physical activity directly targets
modifiable risk factors before disease onset. Blood glucose screening represents secondary prevention (early detection). Support groups and
disease management programs represent tertiary prevention (management of existing disease). ATI 2026/2027 guidelines classify health
education about lifestyle modifications as a cornerstone of primary prevention in community health practice.
Q3: A nurse is reviewing a report indicating that malaria is consistently present in a particular geographic region at a low,
expected level. How should the nurse classify this disease pattern?
A. Endemic [CORRECT]
B. Epidemic
C. Pandemic
D. Sporadic
Correct Answer: A
Rationale: An endemic disease is one that is constantly present in a population at a baseline, expected level within a specific geographic area.
Malaria in endemic regions maintains a steady low-level transmission pattern. An epidemic involves a sudden increase above the expected
level. A pandemic refers to worldwide spread. Sporadic refers to diseases occurring infrequently and irregularly. ATI 2026/2027 content
emphasizes that endemic recognition is fundamental for community health assessment and resource allocation.

,Q4: Which component of the epidemiologic triad (Agent-Host-Environment Model) is the nurse targeting by providing
influenza immunizations to residents of a long-term care facility?
A. Agent
B. Host [CORRECT]
C. Environment
D. Vector
Correct Answer: B
Rationale: The epidemiologic triad consists of agent, host, and environment. Immunizations increase host resistance by stimulating the
immune system, thereby strengthening host defenses against the infectious agent. The agent is the influenza virus itself, and the environment
includes physical and social conditions that influence exposure. There is no vector in the triad for influenza. ATI 2026/2027 guidelines
highlight the Agent-Host-Environment model as foundational for understanding disease causation and planning preventive interventions.
Q5: A public health nurse is reviewing mortality and morbidity data for a community. Which statement correctly
differentiates these two measures?
A. Morbidity refers to the incidence of death, while mortality refers to the incidence of disease
B. Morbidity refers to the incidence of disease, while mortality refers to the incidence of death [CORRECT]
C. Both terms refer to the same health indicator measured at different time points
D. Morbidity measures new cases only, while mortality measures all existing cases
Correct Answer: B
Rationale: Morbidity measures the frequency or incidence of disease in a population, serving as a key health indicator for community
assessment. Mortality measures the frequency or incidence of death in a population. These are distinct epidemiological measures used
together to assess community health status. The other options contain incorrect definitions. ATI 2026/2027 standards require nurses to
accurately differentiate morbidity and mortality when interpreting community health data for program planning.
Q6: A community health nurse coordinates a mammography screening program for women aged 40 and older in a rural
community. Which level of prevention does this program represent?
A. Primary prevention
B. Secondary prevention [CORRECT]
C. Tertiary prevention
D. Quaternary prevention
Correct Answer: B
Rationale: Mammography screening represents secondary prevention, which focuses on early detection and prompt treatment of disease.
The goal is to identify breast cancer at an early stage when treatment is most effective. Primary prevention would aim to prevent breast
cancer from developing (e.g., risk factor modification). Tertiary prevention focuses on rehabilitation and managing established disease to
prevent complications. Quaternary prevention is not a standard level in the public health framework. ATI 2026/2027 guidelines emphasize
that screening programs (Pap smears, mammography, colonoscopy) are classic examples of secondary prevention.
Q7: During a community health assessment, the nurse notes that a disease has rapidly spread to a large number of people in a
short time within a single city. Which term best describes this occurrence?
A. Endemic
B. Pandemic
C. Epidemic [CORRECT]
D. Outbreak
ATI RN Community Health CMS Exam 2026/2027 | Page 2
,Correct Answer: C
Rationale: An epidemic is defined as the rapid spread of disease to a large number of people in a short time within a specific geographic
area or population. While an outbreak is similar, epidemic is the broader and more appropriate term for widespread community-level
transmission. An endemic disease is constantly present at baseline levels. A pandemic refers to global spread across multiple countries or
continents. ATI 2026/2027 content stresses the importance of nurses recognizing epidemic patterns to initiate timely public health responses.
Q8: A public health nurse is implementing a rehabilitation program for stroke survivors that includes physical therapy,
occupational therapy, and support groups. Which level of prevention is being implemented?
A. Primary prevention
B. Secondary prevention
C. Tertiary prevention [CORRECT]
D. Primordial prevention
Correct Answer: C
Rationale: Tertiary prevention focuses on rehabilitation and management of chronic disease or conditions to minimize disability, improve
quality of life, and prevent further complications. Stroke rehabilitation programs with physical and occupational therapy are classic tertiary
prevention interventions. Primary prevention would aim to prevent strokes from occurring. Secondary prevention involves early detection
(e.g., screening for hypertension). Primordial prevention addresses underlying social and environmental conditions. ATI 2026/2027
guidelines highlight rehabilitation services as essential components of tertiary prevention in community health.
Q9: A nurse is calculating the prevalence of hypertension in a community of 50,000 people. If 5,000 individuals currently
have hypertension (including 500 newly diagnosed this year), what is the prevalence?
A. 500/50,000
B. 5,000/50,000 [CORRECT]
C. 4,500/49,500
D. 500/49,500
Correct Answer: B
Rationale: Prevalence measures the total number of existing cases (both new and pre-existing) in a population at a given time. In this
scenario, 5,000 individuals currently have hypertension out of a total population of 50,000. The 500 newly diagnosed cases are already
included in the 5,000 total. Incidence would be 500/49,500 (new cases divided by the population at risk). ATI 2026/2027 competency
standards require community health nurses to calculate and interpret prevalence rates for community health assessment and resource
planning.
Q10: The World Health Organization (WHO) declares COVID-19 a global health emergency with cases reported on every
continent. Which epidemiological term applies to this situation?
A. Endemic
B. Epidemic
C. Pandemic [CORRECT]
D. Hyperendemic
Correct Answer: C
Rationale: A pandemic refers to the worldwide spread of a new disease affecting large numbers of people across multiple countries or
continents. When a disease reaches global proportions, it is classified as a pandemic rather than an epidemic (which is localized) or endemic
(which is constantly present at baseline). Hyperendemic refers to persistent, high levels of disease in a specific area. ATI 2026/2027
guidelines emphasize pandemic preparedness as a critical competency for community health nurses, including understanding the
epidemiological definitions that trigger different levels of public health response.

, Q11: Which intervention by a community health nurse best exemplifies the use of the epidemiologic triad to prevent disease
transmission?
A. Prescribing antibiotics for a patient with strep throat
B. Implementing a water purification system to eliminate a pathogen from the water supply [CORRECT]
C. Conducting a blood pressure screening at a senior center
D. Referring a patient with chronic obstructive pulmonary disease to pulmonary rehabilitation
Correct Answer: B
Rationale: Implementing a water purification system targets the environment component of the epidemiologic triad by removing or
neutralizing the infectious agent in the environmental reservoir. The epidemiologic triad (Agent-Host-Environment Model) provides a
framework for understanding disease causation and identifying intervention points. Water purification addresses the environment
component by preventing exposure to the agent. Prescribing antibiotics targets the agent after disease has occurred. Blood pressure screening
is secondary prevention, and pulmonary rehabilitation is tertiary prevention. ATI 2026/2027 content emphasizes applying the triad model to
design comprehensive prevention strategies.
Q12: A nurse is providing tuberculosis (TB) screening using the Mantoux tuberculin skin test at a homeless shelter. Which
level of prevention does this represent?
A. Primary prevention
B. Secondary prevention [CORRECT]
C. Tertiary prevention
D. Health promotion
Correct Answer: B
Rationale: TB screening with the Mantoux tuberculin skin test represents secondary prevention, which focuses on early detection of disease
in asymptomatic individuals. Identifying TB infection early allows for prompt treatment, reducing transmission and improving outcomes.
Primary prevention for TB would include Bacille Calmette-Guerin (BCG) vaccination or infection control measures. Tertiary prevention
would involve directly observed therapy (DOT) and rehabilitation. ATI 2026/2027 guidelines list TB testing as a core secondary prevention
strategy for high-risk populations such as homeless individuals.
Q13: A community health nurse is educating parents about the childhood immunization schedule recommended by the
Centers for Disease Control and Prevention (CDC). Which statement by a parent indicates an understanding of primary
prevention?
A. "I will bring my child in for annual well-check visits to monitor growth and development."
B. "I will make sure my child receives all recommended vaccines to prevent infectious diseases." [CORRECT]
C. "I will have my child tested for lead exposure at their next check-up."
D. "I will enroll my child in a weight management program to prevent obesity complications."
Correct Answer: B
Rationale: Immunizations are a primary prevention measure because they prevent disease before it occurs by stimulating the immune system
to produce antibodies against specific pathogens. The CDC immunization schedule provides evidence-based guidance for vaccine
administration across the lifespan. Annual well-checks involve monitoring (secondary/tertiary elements). Lead testing is secondary
prevention (screening). Weight management programs for diagnosed conditions are tertiary prevention. ATI 2026/2027 guidelines
emphasize immunizations as a fundamental primary prevention strategy in community health nursing practice.
Q14: A public health nurse is analyzing a community health needs assessment and finds that the incidence rate of a disease is
increasing while the prevalence rate remains stable. Which interpretation is most accurate?
A. The disease is being cured more quickly, balancing new cases [CORRECT]
B. The population at risk is decreasing
