Section 1: Cellular Adaptation, Injury, and Inflammation
(Questions 1–25)
1. Which cellular adaptation is characterized by an increase
in cell size but not cell number?
,A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B. Hypertrophy
Rationale: Hypertrophy is an increase in cell size without an
increase in cell number. Hyperplasia involves increased cell
number. Metaplasia involves replacement of one cell type
with another. Dysplasia refers to disordered cellular growth
and is often a precursor to malignancy.
2. A patient with chronic obstructive pulmonary disease
(COPD) presents with worsening dyspnea and a productive
cough. Which pathophysiological mechanism is primarily
responsible for the airflow limitation in this patient?
A. Destruction of alveolar walls leading to decreased surface
area for gas exchange
B. Airway inflammation, mucus hypersecretion, and airway wall
thickening
C. Pulmonary vasoconstriction leading to increased pulmonary
artery pressure
D. Decreased surfactant production causing alveolar collapse
Correct Answer: B. Airway inflammation, mucus hypersecretion,
and airway wall thickening
Rationale: Airflow limitation in COPD results from a
combination of airway inflammation, mucus
hypersecretion, and airway wall thickening. While alveolar
destruction occurs in emphysema, the primary mechanism
involves chronic inflammation and structural changes in the
airways.
,3. Which of the following best describes the
pathophysiology of iron deficiency anemia?
A. Decreased production of erythropoietin
B. Insufficient iron stores leading to decreased hemoglobin
synthesis
C. Autoimmune destruction of red blood cells
D. Genetic mutation affecting hemoglobin structure
Correct Answer: B. Insufficient iron stores leading to decreased
hemoglobin synthesis
Rationale: Iron deficiency anemia results from insufficient
iron stores, which impairs hemoglobin synthesis. This leads
to microcytic, hypochromic red blood cells.
4. A patient presents with acute chest pain that worsens
with inspiration and is relieved by leaning forward. A
pericardial friction rub is auscultated. Which
pathophysiological process is most likely occurring?
A. Myocardial ischemia
B. Pericardial inflammation
C. Pulmonary embolism
D. Aortic dissection
Correct Answer: B. Pericardial inflammation
Rationale: Pericarditis is characterized by inflammation of
the pericardial sac, causing chest pain that worsens with
inspiration and is relieved by leaning forward. A pericardial
friction rub is a classic finding. Myocardial ischemia pain
does not typically change with position, pulmonary
embolism presents with dyspnea and hypoxia, and aortic
dissection presents with tearing pain radiating to the back.
, 5. Which cellular adaptation involves the replacement of
one mature cell type with another mature cell type?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: C. Metaplasia
Rationale: Metaplasia is the reversible replacement of one
mature cell type with another, often in response to chronic
irritation. For example, squamous metaplasia in the
respiratory tract of smokers.
6. Which type of cell death is characterized by cell swelling,
organelle disruption, and inflammation?
A. Apoptosis
B. Necrosis
C. Autophagy
D. Senescence
Correct Answer: B. Necrosis
Rationale: Necrosis is a pathological form of cell death
characterized by cell swelling, organelle disruption, and an
inflammatory response. Apoptosis is programmed cell
death without inflammation.
7. Which of the following is NOT part of Virchow's Triad?
A. Hypercoagulability
B. Damage to endothelial cells
C. Sympathetic tone
D. Turbulent blood flow
Correct Answer: C. Sympathetic tone
