*INTRODUCTION*
,This examination is designed to evaluate comprehensive understanding of
pathophysiological mechanisms underlying human disease processes. It assesses your
ability to apply foundational scientific principles to clinical scenarios, interpret disease
progression, and make informed diagnostic and therapeutic decisions. Questions include
multiple-choice and scenario-based formats to simulate real-world healthcare reasoning.
Emphasis is placed on integrating anatomical, physiological, and biochemical knowledge
to understand disease development, progression, and systemic impact across organ
systems.
SECTION ONE: QUESTIONS 1–50
Question 1
Which cellular adaptation is most commonly seen in the respiratory tract of chronic
smokers?
A. Hyperplasia
B. Metaplasia
C. Atrophy
D. Dysplasia
,🟢 Correct Answer: B. Metaplasia
🔴 Explanation: Chronic irritation from smoking causes replacement of normal ciliated
epithelium with squamous epithelium as a protective adaptation.
Question 2
Which type of necrosis is classically associated with tuberculosis infection?
A. Liquefactive necrosis
B. Coagulative necrosis
C. Caseous necrosis
D. Fat necrosis
🟢 Correct Answer: C. Caseous necrosis
🔴 Explanation: Tuberculosis produces a cheese-like necrotic tissue appearance known as
caseous necrosis.
Question 3
What is the primary mediator responsible for vasodilation during acute inflammation?
A. Histamine
B. Fibrin
, C. Albumin
D. Keratin
🟢 Correct Answer: A. Histamine
🔴 Explanation: Histamine released from mast cells causes vasodilation and increased
vascular permeability.
Question 4
Which condition is most associated with decreased oncotic pressure?
A. Hypertension
B. Liver cirrhosis
C. Asthma
D. Diabetes mellitus
🟢 Correct Answer: B. Liver cirrhosis
🔴 Explanation: Reduced albumin production in liver disease lowers oncotic pressure,
leading to edema.
Question 5
What is the primary cause of hypoxemia in pulmonary embolism?
