This comprehensive Pathophysiology Exam 3 study guide is designed to assess and reinforce
understanding of mechanisms of disease, alterations in normal physiology, clinical
manifestations, complications, and principles of patient assessment. The multiple-choice
format emphasizes both foundational knowledge and application of pathophysiologic
concepts to realistic clinical situations. Effective preparation requires more than memorizing
disease names: learners should understand causal relationships, physiologic mechanisms,
characteristic findings, and the rationale behind appropriate interventions. The questions
progressively incorporate recall, interpretation, clinical reasoning, and distinctions among
related disorders to support examination-style preparation and practical understanding of
pathophysiology.
SECTION ONE: QUESTIONS 1–100
Question 1. Which cellular adaptation occurs when a cell increases in size in response to
increased workload?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
Correct Answer: B. Hypertrophy
,Explanation: Hypertrophy is an increase in individual cell size, usually caused by increased
workload or hormonal stimulation. It is particularly important in tissues such as cardiac and
skeletal muscle, where mature cells have limited ability to divide.
Question 2. A patient develops an enlarged left ventricle after years of systemic
hypertension. Which pathophysiologic process best explains this finding?
A. Hyperplasia
B. Metaplasia
C. Hypertrophy
D. Atrophy
Correct Answer: C. Hypertrophy
Explanation: Chronic pressure overload increases the workload of ventricular myocytes. The
individual cardiac muscle cells enlarge, producing ventricular hypertrophy. Persistent
hypertrophy can eventually impair ventricular compliance and function.
Question 3. Which cellular adaptation involves replacement of one differentiated adult cell
type by another differentiated cell type?
A. Metaplasia
B. Dysplasia
C. Hypertrophy
D. Necrosis
Correct Answer: A. Metaplasia
Explanation: Metaplasia is a reversible adaptation in which one mature cell type is replaced
by another mature cell type better able to tolerate a persistent stressor. Continued exposure
to the stressor may increase the risk of dysplasia and malignancy.
Question 4. Which feature most clearly distinguishes apoptosis from necrosis?
A. Apoptosis always produces severe inflammation
B. Apoptosis involves uncontrolled cellular swelling
C. Apoptosis is a regulated form of cell death
D. Apoptosis occurs only after infection
Correct Answer: C. Apoptosis is a regulated form of cell death
Explanation: Apoptosis is programmed, regulated cell death that generally removes
individual damaged or unnecessary cells without the extensive inflammatory response
typically associated with necrosis.
Question 5. During acute inflammation, which vascular change occurs first?
, A. Permanent vascular obstruction
B. Brief vasoconstriction followed by vasodilation
C. Immediate thrombosis of all local vessels
D. Complete cessation of blood flow
Correct Answer: B. Brief vasoconstriction followed by vasodilation
Explanation: Acute inflammation typically begins with a brief transient vasoconstriction
followed by arteriolar vasodilation. Vasodilation increases local blood flow and contributes
to redness and warmth.
Question 6. Which inflammatory mediator is strongly associated with increased vascular
permeability during acute inflammation?
A. Histamine
B. Hemoglobin
C. Insulin
D. Albumin
Correct Answer: A. Histamine
Explanation: Histamine released primarily from mast cells promotes vasodilation and
increases vascular permeability. These effects contribute to edema and other cardinal
manifestations of acute inflammation.
Question 7. A patient with acute bacterial inflammation has neutrophils migrating from the
bloodstream into infected tissue. Which process describes movement of leukocytes through
the vessel wall?
A. Chemotaxis
B. Diapedesis
C. Opsonization
D. Phagocytosis
Correct Answer: B. Diapedesis
Explanation: Diapedesis is the movement of leukocytes through the endothelial layer of
blood vessels into surrounding tissues. Chemotaxis, in contrast, describes directed
movement toward chemical signals.
Question 8. Which leukocyte is typically the predominant cell during the early phase of acute
bacterial inflammation?
A. Neutrophil
B. Lymphocyte
C. Plasma cell
D. Eosinophil
