🩺 Foundations & Core Functions of Public Health
Q1: A community health nurse is analyzing data for influenza in a metropolitan
area. In 2024, there were 450 new cases of influenza in a population of 500,000.
What is the annual incidence rate per 100,000 population?
• A. 45 per 100,000
• B. 90 per 100,000
• C. 450 per 100,000
• D. 0.09 per 100,000
Correct Answer: B. 90 per 100,000
Rationale: The incidence rate is calculated as (Number of new cases / Total
population) x 100,000. (,000) x 100,000 = 90 per 100,000.
Q2: Which activities represent the core public health functions as defined by
the Institute of Medicine? (Select all that apply.)
• A. Assessment
• B. Policy Development
• C. Diagnosis of individual illness
• D. Assurance
• E. Treatment planning for hospitalized patients
Correct Answers: A, B, D
Rationale: The three core public health functions are assessment (systematic data
collection and monitoring), policy development (developing and implementing
health policies), and assurance (making sure essential health services are available).
Q3: Making sure that essential community-oriented health services are
available defines which of the core public health functions?
• A. Policy development
, • B. Assessment
• C. Assurance
• D. Scientific knowledge-based care
Correct Answer: C. Assurance
Rationale: Assurance is the core function that focuses on ensuring the availability of
essential personal health services for people who would otherwise not receive care.
🌿 Environmental Health & Epidemiology
Q4: Which of the following statements best describes the relationship between
the environment and health?
• A. Because of the large number of variables involved, the relationship
between environment and health cannot be researched.
• B. Because the environment has such long-term effects on health, research
findings are not yet available.
• C. Research shows that a healthy environment has limited impact on one's
health.
• D. Research shows that a healthy environment increases quality of life and
years of healthy living.
Correct Answer: D. Research shows that a healthy environment increases quality
of life and years of healthy living.
Rationale: A healthy environment is known to increase quality of life and years of
healthy living. Environmental factors contribute to nearly 25% of all deaths and
increase the global disease burden.
Q5: An example of a point source of air pollution is:
• A. A smoke stack
• B. The number of cars and trucks
• C. How much fossil fuel is consumed in a community
• D. Ground ozone levels
Correct Answer: A. A smoke stack
Rationale: Point sources are identifiable, single sources of pollution, such as a smoke
stack from a factory. Cars and trucks are mobile, non-point sources.
Q6: The epidemiological triangle consists of:
• A. Host, agent, environment
, • B. Person, place, time
• C. Incidence, prevalence, mortality
• D. Primary, secondary, tertiary prevention
Correct Answer: A. Host, agent, environment
Rationale: The epidemiological triangle is a traditional model for explaining the
interaction of factors that cause disease, consisting of the host, the agent, and the
environment.
🛡️ Levels of Prevention & Community Health Nursing Roles
Q7: A community health nurse is designing an intervention to reduce childhood
obesity. Which strategy represents primary prevention?
• A. Establishing school-based nutrition education and physical activity
programs for all elementary students
• B. Screening overweight children for prediabetes
• C. Providing insulin management education to children with diagnosed
diabetes
• D. Offering bariatric surgery referral for morbidly obese adolescents
Correct Answer: A. Establishing school-based nutrition education and physical
activity programs for all elementary students
Rationale: Primary prevention aims to prevent a disease or condition before it
occurs. Nutrition and physical activity programs for all students are a health
promotion strategy designed to prevent obesity.
Q8: What would be the proper term for the action of the school health nurse
arranging for all the students in the elementary school to receive H1N1
immunizations?
• A. Health education
• B. Secondary prevention
• C. Specific protection
• D. Tertiary prevention
Correct Answer: C. Specific protection
Rationale: Immunization is a form of specific protection, which is a primary
prevention strategy. It protects the host against a specific disease.
Q9: A nurse who works on the surgical unit at the local hospital was asked by
the home health unit to make a home visit to a patient who had been
, discharged the previous day and to give follow-up care. What kind of nursing
would this nurse be doing?
• A. Acute care hospital nursing
• B. Community-based nursing
• C. Community health nursing
• D. Public health nursing
Correct Answer: B. Community-based nursing
Rationale: Community-based nursing focuses on providing care for individuals and
families in the community where they live, work, and go to school. It is illness-
oriented and focuses on managing acute or chronic conditions.
Q10: A community health nurse is completing an environmental exposure
history. What data would a nurse collect when asking questions about the first
"P" in the mnemonic I PREPARE?
• A. Present work
• B. Potential exposures
• C. Personal protective equipment use
• D. Problems with health
Correct Answer: A. Present work
Rationale: In the "I PREPARE" mnemonic used for environmental exposure history,
the first "P" stands for "Present work".
💡 Additional Practice Questions
Q11: A community health nurse found a very small number of families in the
community who were desperately in need of basic preventive health services.
Which ethical approach supports expending agency resources on these few, but
needy, families?
• A. Beneficence suggests focusing on the most needy, so resources should be
expended on these families.
• B. Deontological ethics suggest that the nurse must give priority to the
intervention that would have the broadest impact.
• C. Utilitarianism (the most good for the largest number) would suggest
continuing to focus on broader community needs.
• D. Virtue ethics would suggest focusing on these families to support the
nurse's own character development.
Correct Answer: A. Beneficence
