Introduction
This document presents 100 original items aligned with the RN Community Health course blueprint for
the 2026/2027 final actual exam. The content is organized into four balanced domains: Epidemiology,
Demographics, and Health Promotion; Communicable Diseases and Environmental Health; Vulnerable
Populations and Community Assessment; and Disaster Management, Case Management, and Public
Health Policy. Every item is paired with a rationale grounded in official RN Community Health course
objectives, foundational public health nursing resources such as Stanhope and Lancaster, and current
evidence-based community health standards from the CDC and WHO. This set is designed to reinforce
the RN Community Health course objectives for final actual exam readiness and clinical proficiency in
population-focused care, community assessment, health protection, case management, and public health
policy. A full answer key, a domain score tracker, and supporting citations follow the items.
Actual Questions
Domain: Epidemiology, Demographics, and Health Promotion
1. A county health department identifies 120 recently diagnosed cases of type 2 diabetes
among 20,000 residents during a one-year period. Which epidemiological measure does
this figure represent?
A. Prevalence proportion
B. Incidence rate
C. Attack rate
D. Case fatality rate
Correct Answer: B
Rationale: Incidence measures the occurrence of recently diagnosed cases in a population at risk
during a specified period, distinguishing it from prevalence, which counts all existing cases at one
point in time.
2. A community survey finds that 340 of 4,000 adults currently have hypertension. This
finding represents which measure?
A. Cumulative incidence
B. Incidence density
C. Point prevalence
D. Attack rate
Correct Answer: C
Rationale: Prevalence reflects all existing cases at a single point in time, whereas incidence reflects
recently diagnosed cases over an interval.
3. Forty-eight of 60 attendees of a catered banquet develop gastroenteritis within two days.
The proportion of 48 to 60 describes which measure?
RN Community Health Final Actual Exam 2026/2027 | Verified Questions
, A. Attack rate
B. Prevalence rate
C. Crude mortality rate
D. Relative risk
Correct Answer: A
Rationale: The attack rate is an incidence proportion specific to a defined group over a short
outbreak period.
4. The number of deaths in a community during a year divided by the mid-year population,
expressed per 1,000 residents, defines which rate?
A. Case fatality rate
B. Age-specific fertility rate
C. Proportional mortality ratio
D. Crude death rate
Correct Answer: D
Rationale: The crude death rate relates total deaths to the total population without adjustment for
age or other characteristics.
5. During an outbreak, 12 of 150 confirmed infected individuals die. This ratio represents
which measure?
A. Case fatality rate
B. Attack rate
C. Crude death rate
D. Point prevalence
Correct Answer: A
Rationale: Case fatality is the proportion of diagnosed cases that die, reflecting the lethality of the
condition.
6. In a cohort investigation, smokers develop lung cancer at 90 per 100,000 and
nonsmokers at 15 per 100,000. The ratio of 90 to 15, which equals 6, represents which
measure?
A. Odds ratio
B. Relative risk
C. Attributable risk
D. Population attributable fraction
Correct Answer: B
Rationale: Relative risk compares the incidence of disease among the exposed with the incidence
among the unexposed in a cohort design.
7. In a case-control investigation, the odds of exposure among cases are divided by the odds
of exposure among controls. This calculation yields which measure?
A. Relative risk
B. Attack rate
C. Incidence rate
D. Odds ratio
Correct Answer: D
Rationale: The odds ratio estimates the exposure-disease association when incidence cannot be
measured directly, as in case-control designs.
8. Exposed workers experience a disease rate of 40 per 1,000 and unexposed workers 10
per 1,000. The difference of 30 per 1,000 represents which measure?
RN Community Health Final Actual Exam 2026/2027 | Verified Questions
, A. Relative risk
B. Odds ratio
C. Attributable risk
D. Case fatality rate
Correct Answer: C
Rationale: Attributable risk is the absolute difference in risk between exposed and unexposed
groups, quantifying excess cases attributable to exposure.
9. A screening tool correctly identifies 180 of 200 people who actually have a disease. This
describes the tool's:
A. Specificity
B. Positive predictive value
C. Interrater reliability
D. Sensitivity
Correct Answer: D
Rationale: Sensitivity is the proportion of people with the disease who are correctly identified as
positive.
10. A screening tool correctly classifies 950 of 1,000 people who do not have a disease as
negative. This describes the tool's:
A. Sensitivity
B. Specificity
C. Negative predictive value
D. Face validity
Correct Answer: B
Rationale: Specificity is the proportion of people without the disease who are correctly identified as
negative.
11. The likelihood that a person with a positive screening result actually has the condition
varies with disease prevalence and is termed:
A. Sensitivity
B. Specificity
C. Positive predictive value
D. Internal consistency
Correct Answer: C
Rationale: Positive predictive value is influenced by prevalence; as prevalence falls, the predictive
value of a positive result declines.
12. A disease that is consistently present at a baseline level within a geographic area is
classified as:
A. Epidemic
B. Endemic
C. Pandemic
D. Sporadic
Correct Answer: B
Rationale: Endemic refers to the usual, ongoing presence of a disease in a population; epidemic
refers to cases in excess of what is expected.
13. Many residents of one apartment building become ill within 24 hours after a single
contaminated water supply event. This pattern indicates which type of outbreak?
A. Propagated outbreak
