SECTION 1: EPIDEMIOLOGY FUNDAMENTALS & KEY TERMINOLOGY
(Questions 1–20)
1. What is the definition of epidemiology?
,A) The study of individual patient care and treatment outcomes
B) The branch of medicine that deals with the incidence, distribution, and possible
control of diseases and other factors relating to health
C) The study of healthcare financing and policy
D) The administration of healthcare systems
,,,,answer,,,,: B) The branch of medicine that deals with the incidence,
distribution, and possible control of diseases and other factors relating to
health
Rationale: Epidemiology provides the scientific foundation for understanding
disease patterns in populations and developing prevention strategies. It focuses on
populations rather than individuals and seeks to identify risk factors and causes of
disease.
2. Which of the following best describes "population health"?
A) Health outcomes of individuals receiving care in hospitals
B) Health outcomes of a group of people and the distribution of those outcomes
within the group
C) The financial management of healthcare organizations
D) The study of individual genetic predispositions to disease
,,,,answer,,,,: B) Health outcomes of a group of people and the distribution of
those outcomes within the group
Rationale: Population health focuses on improving health outcomes for entire
populations rather than individuals. It considers the distribution of health outcomes
within groups and addresses the factors that influence these outcomes.
,3. What are vital statistics?
A) Measurements of patient satisfaction in healthcare settings
B) The collection, tabulation, and interpretation of data concerning birth, marriage,
divorce, sickness, and death
C) Statistics related to hospital readmission rates
D) Data on medication errors in hospitals
,,,,answer,,,,: B) The collection, tabulation, and interpretation of data
concerning birth, marriage, divorce, sickness, and death
Rationale: Vital statistics form the backbone of population health surveillance and
health planning. They provide important outcome measures that can be analyzed
over time to detect health disparities.
4. Define morbidity.
A) The number of deaths in a population
B) The presence of illness in a population
C) The number of births in a population
D) The rate of hospitalization in a population
,,,,answer,,,,: B) The presence of illness in a population
Rationale: Morbidity measures help quantify the burden of disease and inform
resource allocation. It refers to the state of being diseased or the incidence of
disease within a population.
, 5. Define mortality.
A) The presence of illness in a population
B) Related to the tracking of deaths in a population
C) The number of new cases of disease
D) The rate of recovery from illness
,,,,answer,,,,: B) Related to the tracking of deaths in a population
Rationale: Mortality rates are fundamental measures for comparing health
outcomes across populations. Mortality data helps identify leading causes of death
and evaluate public health interventions.
6. What is the definition of incidence?
A) The number or proportion of cases of a disease present in a population at a
specific time
B) The number of new cases of a disease or condition in a population over a
specified period of time
C) The total number of deaths from a disease
D) The proportion of people who die from a disease
,,,,answer,,,,: B) The number of new cases of a disease or condition in a
population over a specified period of time
Rationale: Incidence rates reflect how quickly disease occurs in a population and
are essential for understanding disease etiology. Incidence is a measure of risk.
