Question 1
Which of the following best describes pathophysiology?
A. Study of normal body function
B. Study of the disordered physiological processes associated with disease
C. Study of pharmacology
D. Study of anatomy
Pathophysiology focuses on how diseases alter normal physiological processes.
Question 2
Which cellular adaptation involves an increase in cell size?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
Hypertrophy is an increase in the size of cells, often in response to increased
workload.
Question 3
Which type of cellular adaptation involves an increase in cell number?
A. Hyperplasia
B. Hypertrophy
,C. Atrophy
D. Dysplasia
Hyperplasia is an increase in cell number, often in response to hormonal
stimulation or chronic injury.
Question 4
Which of the following best defines atrophy?
A. Increase in cell size
B. Decrease in cell size or number
C. Replacement of one cell type with another
D. Uncontrolled cell growth
Atrophy occurs due to disuse, aging, or reduced blood supply.
Question 5
Which term describes the replacement of one mature cell type with another?
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Hypertrophy
Metaplasia is often an adaptive response to chronic irritation or inflammation.
Question 6
Which of the following is considered a reversible cell injury?
A. Necrosis
B. Apoptosis
C. Cellular swelling
D. Gangrene
,Reversible injury can be corrected if the stressor is removed; swelling is a common
early sign.
Question 7
Which type of cell death is typically programmed and controlled?
A. Apoptosis
B. Necrosis
C. Coagulative necrosis
D. Liquefactive necrosis
Apoptosis is an organized process to remove damaged or unneeded cells without
triggering inflammation.
Question 8
Which type of necrosis is most commonly associated with ischemia in the heart?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fat
Coagulative necrosis preserves tissue architecture temporarily and is typical in
myocardial infarction.
Question 9
Which type of necrosis is typically seen in bacterial infections of the brain?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fat
, Liquefactive necrosis results in tissue digestion and a liquid mass, common in
abscesses and brain infarcts.
Question 10
Which type of necrosis is associated with tuberculosis infections?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fat
Caseous necrosis has a cheese-like appearance and is characteristic of
granulomatous infections like TB.
Question 11
Which of the following best describes gangrene?
A. Programmed cell death
B. Extensive tissue necrosis often due to ischemia
C. Mild reversible injury
D. Cellular swelling
Gangrene can be dry, wet, or gas type and results from severe ischemia or
infection.
Question 12
Which of the following is a common cause of cellular hypoxia?
A. Oxygen deprivation
B. Toxin exposure
C. Trauma
D. Infection
