QUESTION 1: Which level of prevention focuses on early detection and screening of
disease before symptoms appear?
A. Primary prevention B. Tertiary prevention C. Secondary prevention D. Quaternary prevention
E. Primordial prevention
CORRECT ANSWER: C. Secondary prevention RATIONALE: Secondary
prevention targets early detection through screening and diagnosis before the individual is
symptomatic, aiming to halt or slow disease progression. Examples include mammograms, Pap
smears, and blood pressure screenings.
QUESTION 2: A community health nurse is conducting a windshield survey. Which
action BEST describes this assessment method?
A. Reviewing vital statistics at the health department B. Conducting door-to-door interviews
with residents C. Observing the community while driving through it D. Analyzing census data
from government records E. Distributing written surveys to community members
CORRECT ANSWER: C. Observing the community while driving through it
RATIONALE: A windshield survey involves systematically observing the community from
a vehicle to gather data about the environment, housing, businesses, people, and resources. It is a
quick, informal community assessment tool.
QUESTION 3: The nurse is educating a community about herd immunity. Which
statement BEST explains this concept?
A. Immunity is achieved when everyone in the community is vaccinated B. Animals in the
community are vaccinated to prevent zoonotic disease C. A sufficient proportion of the
population is immune, reducing disease spread to unimmunized individuals D. Natural immunity
is always superior to vaccine-acquired immunity E. Immunity is only possible after surviving the
actual disease
CORRECT ANSWER: C. A sufficient proportion of the population is immune,
reducing disease spread to unimmunized individuals RATIONALE: Herd immunity
(community immunity) occurs when enough people are immune to an infectious disease,
,indirectly protecting those who are not immune. It does not require 100% vaccination, but a
critical threshold must be reached.
QUESTION 4: Which epidemiological measure describes the number of NEW cases of a
disease in a population during a specific time period?
A. Prevalence B. Mortality rate C. Incidence D. Morbidity rate E. Attack rate
CORRECT ANSWER: C. Incidence RATIONALE: Incidence refers to the
number of new cases of a disease occurring in a defined population over a specific time period.
Prevalence, by contrast, counts all existing cases (both old and new) at a point in time.
QUESTION 5: A public health nurse is planning a health fair for a low-income urban
community. Which approach reflects cultural competence?
A. Providing all materials in English only B. Inviting community leaders to participate in
planning C. Scheduling the event during typical work hours on a weekday D. Offering only
Western medical practices E. Assuming all community members share the same health beliefs
CORRECT ANSWER: B. Inviting community leaders to participate in planning

leaders in planning to ensure services are respectful, relevant, and accessible. Including
community voices improves participation and outcomes.
QUESTION 6: Which of the following is an example of primary prevention?
A. Rehabilitation after a stroke B. Colonoscopy screening for colon cancer C. Insulin therapy for
diabetes management D. Childhood immunization against measles E. Physical therapy after hip
replacement
CORRECT ANSWER: D. Childhood immunization against measles
RATIONALE: Primary prevention prevents disease before it occurs. Immunizations are a
classic example because they prevent the individual from contracting the disease altogether.
QUESTION 7: The nurse calculates a crude death rate for a community. Which data is
needed for this calculation?
,A. Number of deaths from a specific cause divided by total population B. Total number of deaths
divided by the total mid-year population, multiplied by 1,000 C. Number of infant deaths divided
by number of live births D. Number of deaths from chronic disease divided by total deaths E.
Total deaths divided by number of hospital admissions
CORRECT ANSWER: B. Total number of deaths divided by the total mid-year
population, multiplied by 1,000 RATIONALE: The crude death rate is calculated by
dividing the total number of deaths by the total mid-year population, then multiplying by 1,000.
It provides a general measure of mortality in a population without regard to specific causes.
QUESTION 8: A nurse is working with a family using the Family Systems Theory. Which
statement reflects this approach?
A. Each family member's health is assessed independently B. The family is viewed as a unit
where change in one member affects all others C. Family health is determined solely by genetic
factors D. Only the primary breadwinner's health influences family functioning E. Family
members are assessed in isolation from their social context
CORRECT ANSWER: B. The family is viewed as a unit where change in one
member affects all others RATIONALE: Family Systems Theory views the family as
an interconnected system. A change or illness in one member creates ripple effects throughout
the entire family unit, affecting roles, communication, and functioning.
QUESTION 9: Which disease reporting classification requires immediate reporting to
public health authorities?
A. Influenza B. Tuberculosis C. Cholera D. Hepatitis B E. Lyme disease
CORRECT ANSWER: C. Cholera RATIONALE: Cholera is a notifiable
disease that requires immediate (within 24 hours) reporting to public health authorities due to its
epidemic potential and public health significance. It is classified as an immediately notifiable
condition by the CDC.
QUESTION 10: What is the PRIMARY goal of Healthy People 2030?
A. To eliminate all communicable diseases in the United States B. To improve the health and
well-being of all Americans by addressing social determinants of health C. To reduce healthcare
, costs for the federal government D. To mandate universal vaccination for all age groups E. To
increase the number of hospitals in rural communities
CORRECT ANSWER: B. To improve the health and well-being of all Americans by
addressing social determinants of health RATIONALE: Healthy People 2030 focuses
on improving health outcomes and promoting health equity by addressing social determinants of
health, such as education, income, housing, and access to healthcare. It provides science-based
national objectives.
QUESTION 11: Which term describes the proportion of individuals in a population who
HAVE a disease at a specific point in time?
A. Incidence rate B. Attack rate C. Prevalence D. Relative risk E. Attributable risk
CORRECT ANSWER: C. Prevalence RATIONALE: Prevalence is the
proportion of people in a population who have a specific condition at a given point in time (point
prevalence) or over a period of time (period prevalence). It includes both new and existing cases.
QUESTION 12: A nurse is assessing the social determinants of health in a community.
Which factor would be included?
A. The individual's genetic predisposition to disease B. Access to safe housing and employment
opportunities C. The availability of antibiotics in local pharmacies D. Blood pressure readings of
community members E. Cholesterol levels in adults over age 50
CORRECT ANSWER: B. Access to safe housing and employment opportunities
RATIONALE: Social determinants of health (SDOH) are non-medical factors that influence
health outcomes, including housing, employment, education, income, social support, and
neighborhood conditions. These factors significantly shape community health.
QUESTION 13: The epidemiological triad model consists of which three components?
A. Host, vector, environment B. Agent, host, environment C. Person, place, time D.
Susceptibility, exposure, outcome E. Pathogen, carrier, reservoir
CORRECT ANSWER: B. Agent, host, environment RATIONALE: The
epidemiological triad (or triangle) consists of the agent (the causative factor), the host (the
