Graded A+) | New Update 2026-2027 | Wilkes University
Question 1
What are the five essential components of pathophysiology?
A. Etiology, Epidemiology, Pathogenesis, Clinical Manifestations, Outcomes
B. Diagnosis, Treatment, Prognosis, Prevention, Rehabilitation
C. Signs, Symptoms, Laboratory Findings, Imaging Studies, Biopsy Results
D. Genetics, Environment, Lifestyle, Age, Gender
Correct Answer: A. Etiology, Epidemiology, Pathogenesis, Clinical
Manifestations, Outcomes
Rationale: The five essential components of pathophysiology are: 1) Etiology
(causative mechanisms); 2) Epidemiology (risk factors and distribution in
populations); 3) Pathogenesis (disease mechanism); 4) Clinical manifestations
(signs, symptoms and diagnostic criteria); and 5) Outcomes (cure, remission,
chronicity, or death).
Question 2
The "why" of disease—what is the reason for it—what caused it to happen? This
component of disease may be simple or complex.
A. Etiology
B. Epidemiology
C. Pathogenesis
D. Clinical Manifestations
Correct Answer: A. Etiology
,Rationale: Etiology refers to the "why" of disease—the reason for it and what
caused it to happen. It may be simple or complex and represents the causative
mechanisms of disease.
Question 3
Looks at the pattern of disease among groups or aggregates or populations. This
component of disease represents the relationship between numerous
population characteristics (e.g., age, ethnicity, socioeconomic status, geographic
location) and the incidence and prevalence of disease.
A. Etiology
B. Epidemiology
C. Pathogenesis
D. Clinical Manifestations
Correct Answer: B. Epidemiology
Rationale: Epidemiology looks at the pattern of disease among groups or
aggregates or populations. This component represents the relationship between
numerous population characteristics (e.g., age, ethnicity, socioeconomic status,
geographic location) and the incidence and prevalence of disease.
Question 4
Involves the sequence of events that occurs between the stimulus event(s) and
the manifestations of the disease.
A. Etiology
B. Epidemiology
C. Pathogenesis
D. Clinical Manifestations
Correct Answer: C. Pathogenesis
Rationale: Pathogenesis involves the sequence of events that occurs between the
stimulus event(s) and the manifestations of the disease. It describes the disease
mechanism.
,Question 5
Tell an individual and their health care provider that something is wrong, e.g.,
Signs and symptoms.
A. Etiology
B. Epidemiology
C. Pathogenesis
D. Clinical Manifestations
Correct Answer: D. Clinical Manifestations
Rationale: Clinical manifestations tell an individual and their health care provider
that something is wrong, including signs and symptoms.
Question 6
Are relatively easy to understand if you review their definitions (cure, remission,
chronicity, or death).
A. Etiology
B. Epidemiology
C. Clinical Manifestations
D. Outcomes
Correct Answer: D. Outcomes
Rationale: Outcomes are relatively easy to understand if you review their
definitions (cure, remission, chronicity, or death). They represent the final result of
the disease process.
Question 7
What are the 4 common mechanisms that characterize all cell injury and death?
A. ATP depletion, Oxygen and oxygen-derived free radicals, Intracellular calcium
and loss of calcium steady state, Defects in membrane permeability
, B. Infection, Inflammation, Ischemia, Necrosis
C. Genetic mutations, Environmental toxins, Trauma, Metabolic disorders
D. Hypoxia, Hyperoxia, Ischemia, Reperfusion injury
Correct Answer: A. ATP depletion, Oxygen and oxygen-derived free radicals,
Intracellular calcium and loss of calcium steady state, Defects in membrane
permeability
Rationale: The four common mechanisms that characterize all cell injury and
death are: 1) ATP depletion (e.g., Ischemia and Anemia); 2) Oxygen and oxygen-
derived free radicals (e.g., Chemical and radiation injury, ischemia reperfusion
injury, microbial killing by phagocytes, and cellular aging); 3) Intracellular calcium
and loss of calcium steady state (e.g., Ischemia and certain chemicals); and 4)
Defects in membrane permeability (e.g., Certain medications that can lead to liver
or kidney damage).
Question 8
The disease mechanism that is the basis of much of the disease today—and
most of the cases involve hypoxia. Refers to the inability of the cell to produce
adequate energy to fuel normal activities of that particular cell type (cell
membrane pumps and protein synthesis) and function.
A. ATP depletion
B. Free radical injury
C. Calcium overload
D. Membrane permeability defects
Correct Answer: A. ATP depletion
Rationale: ATP depletion is the disease mechanism that is the basis of much of the
disease today—and most of the cases involve hypoxia. It refers to the inability of
the cell to produce adequate energy to fuel normal activities of that particular cell
type (cell membrane pumps and protein synthesis) and function.
