Advanced Pathophysiology Practice Examination
Part 1
Course: NSG 530 – Advanced Pathophysiology
Institution: Wilkes University (Practice Material)
Examination: Comprehensive Practice Exam (Original Content)
Date: August 2026
Table of Contents
1. Instructions
2. Section I – Cellular Pathophysiology
3. Section II – Genetics & Epigenetics
4. Answer Key with Rationales
Instructions
• This practice examination contains 25 original questions.
• Select the single best answer for multiple-choice questions.
• Provide concise but complete responses for short-answer questions.
• Read each question carefully before answering.
Section I – Cellular Pathophysiology (Questions 1–15)
,Question 1
A patient develops swelling after twisting an ankle. Which mediator is primarily responsible for
increasing vascular permeability during acute inflammation?
A. Histamine
B. Erythropoietin
C. Aldosterone
D. Insulin
Correct Answer: A. Histamine
Rationale:
Histamine is rapidly released from mast cells during tissue injury and causes vasodilation and
increased vascular permeability, allowing plasma proteins and leukocytes to enter injured tissues.
Aldosterone regulates sodium balance, erythropoietin stimulates red blood cell production, and
insulin regulates glucose metabolism.
Question 2
Which cellular adaptation occurs when skeletal muscle enlarges following resistance training?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B. Hypertrophy
Rationale:
Hypertrophy refers to an increase in cell size rather than cell number. Adult skeletal muscle has
limited ability to undergo hyperplasia; therefore increased muscle mass primarily results from
hypertrophy.
Question 3
A liver biopsy reveals replacement of one mature epithelial cell type with another because of
chronic irritation. This process is called:
A. Dysplasia
,B. Metaplasia
C. Necrosis
D. Apoptosis
Correct Answer: B. Metaplasia
Rationale:
Metaplasia is a reversible adaptation in which one differentiated cell type is replaced by another
better able to withstand chronic stress. Persistent injury may eventually progress to dysplasia.
Question 4
Which intracellular organelle is primarily responsible for ATP production?
A. Lysosome
B. Nucleus
C. Mitochondrion
D. Golgi apparatus
Correct Answer: C. Mitochondrion
Rationale:
Mitochondria generate ATP through oxidative phosphorylation. Cellular injury commonly
disrupts mitochondrial function, leading to decreased energy production.
Question 5
Short Answer
Explain the difference between apoptosis and necrosis.
Correct Answer:
Apoptosis is programmed, regulated cell death that occurs without triggering significant
inflammation. Necrosis is uncontrolled cell death caused by injury or ischemia and is associated
with membrane rupture and inflammation.
Rationale:
Understanding these two mechanisms is essential because apoptosis is physiologic and energy-
dependent, whereas necrosis results from irreversible cellular injury and contributes to tissue
damage.
, Question 6
During acute inflammation, which leukocyte arrives first?
A. Monocyte
B. Neutrophil
C. Eosinophil
D. Lymphocyte
Correct Answer: B. Neutrophil
Rationale:
Neutrophils are the first responders within hours of injury. Monocytes arrive later and
differentiate into macrophages for tissue cleanup and repair.
Question 7
A patient experiences prolonged tissue ischemia. Which process most directly causes irreversible
cell injury?
A. Increased ATP production
B. Membrane stabilization
C. ATP depletion
D. Protein synthesis increases
Correct Answer: C. ATP depletion
Rationale:
Loss of ATP disrupts ion pumps, causes cellular swelling, calcium influx, and ultimately
irreversible cellular injury.
Question 8
Which inflammatory cytokine is most responsible for fever?
A. IL-1
B. Albumin
C. Hemoglobin
