Core Domains
Cellular Adaptation, Injury, and Death
Inflammation and Tissue Repair
Fluid, Electrolyte, and Acid-Base Balance
Immune System Function and Dysfunction
Genetics and Genetic Disorders
Neoplasia and Cancer Biology
Stress and Disease
Homeostasis and Regulatory Mechanisms

Introduction
This comprehensive examination is designed to assess foundational knowledge and understanding of core
pathophysiological concepts essential for nursing practice. The test evaluates the ability to explain disease
mechanisms, recognize clinical manifestations, and apply pathophysiological principles to patient care scenarios.
Candidates will be challenged with multiple-choice questions that emphasize real-world application, clinical
,reasoning, and the integration of biological and physiological concepts. This assessment serves as a valuable tool
for identifying strengths and areas for focused study prior to the Pathophysiology Exam.
SECTION ONE: QUESTIONS 1–100
1. What is the primary mechanism of cellular injury in ischemia?
A. ATP depletion leading to failure of sodium-potassium pumps
B. Direct damage to cellular membranes by free radicals
C. Activation of the complement cascade
D. Inhibition of protein synthesis
🟢A
🔴 RATIONALE: Ischemia results in hypoxia, which leads to reduced ATP production. Without ATP, the sodium-
potassium pump fails, causing cellular swelling, calcium influx, and eventual cell death. Free radical damage and
complement activation are secondary or associated mechanisms, not primary.
2. What is the hallmark cellular change in reversible cell injury?
,A. Cellular swelling
B. Nuclear fragmentation
C. Fatty accumulation
D. Loss of microvilli
🟢A
🔴 RATIONALE: Cellular swelling (hydropic change) is the hallmark of reversible cell injury, caused by failure of
the sodium-potassium pump and water influx. Nuclear fragmentation, fatty accumulation, and loss of microvilli
are associated with irreversible injury or specific processes.
3. Which type of necrosis is characterized by the formation of a cheese-like, granular appearance?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
🟢C
🔴 RATIONALE: Caseous necrosis, often seen in tuberculosis, has a cheese-like, granular appearance due to the
combination of coagulative and liquefactive necrosis. Coagulative necrosis preserves tissue architecture,
liquefactive necrosis forms a liquid mass, and fat necrosis involves saponification.
, 4. What is the primary role of the inflammatory response?
A. To eliminate the cause of injury and initiate tissue repair
B. To produce antibodies against pathogens
C. To activate the clotting cascade
D. To induce apoptosis
🟢A
🔴 RATIONALE: The inflammatory response is a protective mechanism designed to eliminate the cause of injury,
remove damaged tissue, and initiate repair. Antibody production is part of the adaptive immune response, and
apoptosis is programmed cell death.
5. Which of the following is a cardinal sign of acute inflammation?
A. Fever
B. Vasodilation
C. Malaise
D. Leukocytosis
🟢B
🔴 RATIONALE: Vasodilation is a cardinal sign of acute inflammation, leading to redness (rubor) and heat
(calor). Fever, malaise, and leukocytosis are systemic manifestations, not cardinal local signs.
