Introduction
This comprehensive assessment evaluates the knowledge and
clinical judgment required for population health nursing practice. It
covers epidemiologic principles, community assessment, health
promotion, social determinants, cultural competence, program
planning, policy, and environmental health. Questions are multiple-
choice and scenario-based, emphasizing real-world application,
data interpretation, and decision-making. The examination is
designed to reflect practicum expectations and to strengthen
readiness for safe, evidence-informed population health practice.
SECTION ONE: QUESTIONS 1-100
1. A community health nurse is calculating the incidence rate of a
new disease. Which formula is correct?
,A. 🟢 (Number of new cases / Population at risk) × 1,000
B. (Number of existing cases / Total population) × 1,000
C. (Number of deaths / Total population) × 1,000
D. (Number of new cases / Total population) × 100,000
🔴 RATIONALE: Incidence rate measures the occurrence of new
cases in a population at risk during a specified period. It is
calculated as the number of new cases divided by the population
at risk, multiplied by a constant.
2. A nurse is conducting a community assessment. Which data
source provides subjective information about the community?
A. Census data
B. 🟢 Key informant interviews
C. Vital statistics
D. Morbidity reports
🔴 RATIONALE: Key informant interviews provide subjective,
qualitative data about community perceptions, needs, and
strengths. Census and vital statistics are objective secondary data.
3. Which level of prevention is exemplified by a community-wide
immunization campaign?
A. Primary prevention
B. 🟢 Primary prevention
C. Secondary prevention
D. Tertiary prevention
🔴 RATIONALE: Primary prevention aims to prevent disease
before it occurs. Immunization campaigns are a classic example of
primary prevention.
4. A nurse is evaluating the effectiveness of a screening program.
Which measure is most appropriate?
,A. Incidence rate
B. 🟢 Sensitivity and specificity
C. Prevalence rate
D. Mortality rate
🔴 RATIONALE: Sensitivity and specificity measure the ability of a
screening test to correctly identify those with and without the
disease, respectively. They are key measures for evaluating
screening programs.
5. Which social determinant of health has the greatest impact on
population health outcomes?
A. Access to healthcare
B. 🟢 Socioeconomic status
C. Genetic predisposition
D. Individual health behaviors
🔴 RATIONALE: Socioeconomic status, including income,
education, and occupation, is the strongest predictor of health
outcomes and is a fundamental social determinant of health.
6. A nurse is planning a health promotion program. Which model
is most appropriate for planning, implementing, and evaluating
health promotion programs?
A. Health Belief Model
B. 🟢 PRECEDE-PROCEED Model
C. Transtheoretical Model
D. Social Cognitive Theory
🔴 RATIONALE: The PRECEDE-PROCEED model is a
comprehensive planning framework that guides assessment,
implementation, and evaluation of health promotion programs.
, 7. A community has a high rate of obesity. Which intervention is
an example of secondary prevention?
A. Health education on nutrition
B. 🟢 Screening for diabetes and hypertension
C. Bariatric surgery
D. Community gardens
🔴 RATIONALE: Secondary prevention focuses on early detection
and treatment of disease. Screening for obesity-related conditions
such as diabetes and hypertension is secondary prevention.
8. Which term describes the ability of a test to correctly identify
people who do not have a disease?
A. Sensitivity
B. 🟢 Specificity
C. Positive predictive value
D. Negative predictive value
🔴 RATIONALE: Specificity is the proportion of people without the
disease who test negative. It measures the test's ability to
correctly rule out disease.
9. A nurse is investigating an outbreak of foodborne illness. Which
step is first in the outbreak investigation?
A. 🟢 Establish the existence of an outbreak
B. Implement control measures
C. Perform a case-control study
D. Write a report
🔴 RATIONALE: The first step in an outbreak investigation is to
establish that an outbreak exists by comparing the observed
number of cases to the expected number.
