Section IV Cardiovascular Pathophysiology
Answer Key Correct answers with rationales
Introduction
Course: D236 Pathophysiology
Institution: Western Governors University (WGU)
This original practice examination is designed to reinforce foundational concepts commonly
taught in undergraduate pathophysiology. Questions emphasize understanding disease
mechanisms, clinical reasoning, and application of physiological principles.
Instructions
• Read each question carefully.
• Multiple-choice questions have one best answer unless otherwise stated.
• Short-answer questions should be answered briefly.
• Scenario-based questions require application of pathophysiology concepts.
,Section I – Cellular Function and Disease Processes
Multiple Choice
Question 1
Which cellular adaptation occurs when skeletal muscle increases in size after resistance
training?
A. Hyperplasia
B. Dysplasia
C. Hypertrophy
D. Metaplasia
Question 2
Apoptosis differs from necrosis because apoptosis:
A. Causes extensive inflammation
B. Is an uncontrolled process
C. Is programmed cell death
D. Results from severe trauma only
Question 3
A patient develops liver enlargement after chronic alcohol use. The enlarged hepatocytes
contain excessive triglycerides. This condition is called:
A. Calcification
B. Fatty change
C. Atrophy
D. Necrosis
, Question 4
Which cellular adaptation is most likely to occur in the endometrium during pregnancy?
A. Atrophy
B. Hyperplasia
C. Metaplasia
D. Necrosis
Question 5
Free radicals primarily damage cells by:
A. Increasing ATP production
B. Stabilizing cell membranes
C. Causing oxidative stress
D. Preventing inflammation
Question 6
Which organelle is primarily responsible for ATP production?
A. Nucleus
B. Ribosome
C. Mitochondrion
D. Lysosome
Question 7
A deficiency in oxygen delivery initially causes:
A. Increased aerobic metabolism
B. Decreased ATP production
C. Increased protein synthesis
