Pathophysiology – Comprehensive 100-
Question Practice Exam
Focus: Cellular adaptation, injury & death, inflammation & immunity,
fluid/electrolyte balance, acid-base disorders, genetics, neoplasia, and
multi-system pathophysiology
EXAM OVERVIEW
Pathophysiology is the study of disordered physiological processes
associated with disease or injury. It bridges the gap between basic
sciences (anatomy, physiology, biochemistry) and clinical medicine,
guiding healthcare professionals in diagnosing, managing, and preventing
health conditions .
Key Concepts
• Etiology = the cause of disease (genetic, infectious, environmental)
• Pathogenesis = the sequence of cellular and molecular events
leading to clinical symptoms
• Pathophysiology = the functional changes occurring within the body
as a result of disease
• Cell Injury = reversible (cellular swelling, fatty change) or irreversible
(necrosis, apoptosis)
SECTION 1: Cellular Adaptation, Injury & Death (Questions 1-20)
Q1. Which type of cellular adaptation involves an increase in cell size?
• A) Hyperplasia
• B) Hypertrophy
• C) Atrophy
• D) Metaplasia
,Answer: B – Hypertrophy is an increase in cell size, not number
(hyperplasia). It occurs in response to increased workload or hormonal
stimulation. Cardiac myocytes are permanent cells and cannot undergo
mitosis, so they adapt via hypertrophy .
Q2. A 62-year-old male with long-standing hypertension shows left
ventricular wall thickening. What is the primary cellular mechanism
driving this change?
• A) Hyperplasia due to increased mitotic division
• B) Hypertrophy due to increased protein synthesis
• C) Metaplasia due to chronic mechanical stress
• D) Dysplasia due to genetic mutations in myocytes
Answer: B – Myocardial cells are permanent cells and cannot undergo
mitosis. When faced with chronic increased afterload, myocytes adapt via
hypertrophy, increasing cell size driven by enhanced protein synthesis .
Q3. A patient with chronic GERD develops replacement of the normal
squamous epithelium of the lower esophagus with columnar
epithelium. This cellular adaptation is called:
• A) Hypertrophy
• B) Hyperplasia
• C) Metaplasia
• D) Dysplasia
Answer: C – Metaplasia is the reversible replacement of one differentiated
cell type with another. In Barrett's esophagus, squamous epithelium is
replaced by columnar epithelium as an adaptive response to chronic acid
exposure .
,Q4. A patient's Pap smear shows abnormal changes in the size, shape,
and organization of cervical cells. This finding is best described as:
• A) Metaplasia
• B) Dysplasia
• C) Hypertrophy
• D) Hyperplasia
Answer: B – Dysplasia is characterized by abnormal changes in cell size,
shape, and organization. It is often a precursor to malignancy and is
commonly detected in cervical Pap smears .
Q5. A patient with chronic hypoxia develops increased production of
red blood cells. This is an example of:
• A) Physiologic hyperplasia
• B) Pathologic hyperplasia
• C) Compensatory hyperplasia
• D) Hormonal hyperplasia
Answer: C – Compensatory hyperplasia occurs when the body increases
cell production to compensate for a deficiency. In chronic hypoxia, the
kidneys release erythropoietin, stimulating the bone marrow to produce
more red blood cells .
Q6. Which type of cell death is characterized by cellular swelling,
rupture of the cell membrane, and an inflammatory response?
• A) Apoptosis
• B) Necrosis
• C) Autophagy
• D) Atrophy
, Answer: B – Necrosis is characterized by cellular swelling, rupture of the
cell membrane, and leakage of cellular contents, triggering an
inflammatory response. Apoptosis is programmed cell death without
inflammation .
Q7. Which type of necrosis is typically seen in myocardial infarction?
• A) Liquefactive necrosis
• B) Caseous necrosis
• C) Coagulative necrosis
• D) Fat necrosis
Answer: C – Ischemic injury to solid organs like the heart results in
coagulative necrosis. Tissue architecture is preserved for several days
while cells lose their nuclei .
Q8. Which type of necrosis is most characteristic of tuberculosis?
• A) Coagulative necrosis
• B) Liquefactive necrosis
• C) Caseous necrosis
• D) Fat necrosis
Answer: C – Caseous necrosis has a "cheese-like" appearance and is
typical of mycobacterial infections such as tuberculosis. It represents a
combination of coagulative and liquefactive necrosis .
Q9. Which of the following best describes apoptosis?
• A) Programmed cell death without inflammation
• B) Necrosis with inflammation
• C) Cellular swelling and lysis
