KAPLAN COMMUNITY/PUBLIC HEALTH ASSESSMENT
2026/2027 COMPLETE (100) CURRENT TESTING
QUESTIONS AND CORRECT ANSWERS WITH DETAILED
RATIONALES.
PUBLIC HEALTH
Prepare for the Kaplan Community/Public Health Assessment with a focused study
resource covering essential concepts in community and population-based nursing. It
supports review of health promotion, disease prevention, epidemiology, community
assessment, vulnerable populations, patient education, and public health
interventions. Use the material to reinforce key concepts, strengthen clinical
reasoning, and identify areas that may require additional study. This resource is best
suited for nursing students and NCLEX candidates preparing for community and
public health assessments.
MULTIPLE CHOICE.
EPIDEMIOLOGY & DISEASE SURVEILLANCE
1. A community health nurse is investigating an outbreak of foodborne
illness. Which term describes the number of new cases of a disease in a
population over a specific period?
• A) Prevalence
• B) Incidence
• C) Morbidity
• D) Mortality
Answer: B) Incidence
Rationale: Incidence refers to the number of new cases of a disease
occurring in a population during a specified period. Prevalence refers to
the total number of cases (new and existing) at a given point in time.
Morbidity refers to the state of being diseased, and mortality refers to
death.

2. A nurse is reviewing epidemiological data for a community. The total
number of existing cases of diabetes in the community divided by the
total population is known as:
• A) Incidence rate
• B) Prevalence rate
• C) Attack rate
• D) Case-fatality rate
Answer: B) Prevalence rate
Rationale: Prevalence rate measures the proportion of the population that
has a specific disease at a given point in time. It includes both new and
existing cases. Incidence rate measures new cases only. Attack rate is
used in outbreak investigations, and case-fatality rate measures deaths
among those with the disease.
3. A community health nurse is using the epidemiological triad to
understand disease transmission. Which of the following represents the
three components of the epidemiological triad?
• A) Host, agent, environment
• B) Person, place, time
• C) Susceptibility, exposure, outcome
• D) Primary, secondary, tertiary
Answer: A) Host, agent, environment
Rationale: The epidemiological triad consists of the host (the susceptible
individual), the agent (the cause of disease), and the environment
(external factors that allow transmission). Person, place, and time are
descriptive epidemiological variables. Primary, secondary, and tertiary
refer to levels of prevention.

4. A nurse is investigating a cluster of tuberculosis cases in a homeless
shelter. The nurse identifies that the shelter's ventilation system is
inadequate. This is an example of which component of the
epidemiological triad?
• A) Host
• B) Agent
• C) Environment
• D) Vector
Answer: C) Environment
Rationale: The environment includes external factors that influence
disease transmission, such as ventilation, crowding, sanitation, and
climate. Inadequate ventilation facilitates the spread of airborne diseases
like tuberculosis. The host is the susceptible individual, and the agent is
the organism causing the disease.
5. A community health nurse is calculating the infant mortality rate for a
county. Which formula should the nurse use?
• A) Number of infant deaths / Number of live births × 1,000
• B) Number of infant deaths / Total population × 1,000
• C) Number of infant deaths / Number of women of childbearing age ×
1,000
• D) Number of infant deaths / Number of births × 100,000
Answer: A) Number of infant deaths / Number of live births × 1,000
Rationale: Infant mortality rate is calculated as the number of deaths of
infants under 1 year of age per 1,000 live births in a given year. This is a key
indicator of community health and reflects the quality of prenatal,
obstetric, and pediatric care.

6. A nurse is reviewing the leading causes of death in the United States.
Which of the following is the leading cause of death overall?
• A) Cancer
• B) Heart disease
• C) Stroke
• D) Accidents
Answer: B) Heart disease
Rationale: Heart disease has been the leading cause of death in the
United States for decades, followed by cancer. Stroke and accidents are
also leading causes but are not the top cause overall. Community health
nurses focus on prevention of cardiovascular disease through lifestyle
modifications and screening.
7. A community health nurse is using the "web of causation" model to
understand the multiple factors contributing to a health problem. This
model is most appropriate for understanding:
• A) Infectious diseases with a single cause
• B) Chronic diseases with multiple contributing factors
• C) Acute injuries with a clear cause
• D) Genetic disorders
Answer: B) Chronic diseases with multiple contributing factors
Rationale: The web of causation model recognizes that many health
problems, particularly chronic diseases, have multiple interacting causes
including biological, behavioral, social, and environmental factors. This
model is more appropriate for understanding complex health issues than
the traditional epidemiological triad.
