EDITION) COMPREHENSIVE TEST
BANK QUESTIONS AND ANSWERS.
VERIFIED 2026/2027
1. Which term describes a cellular adaptation where one mature cell type is replaced by a
different mature cell type, often due to chronic irritation?
A. Metaplasia
B. Hyperplasia
C. Dysplasia
D. Anaplasia
Answer: A
Conceptual Explanation: Metaplasia is the replacement of one mature cell type by
another, such as in the respiratory tract of smokers where ciliated columnar epithelium
changes to stratified squamous epithelium.
2. Which type of necrosis is characterized by the conversion of tissue into a liquid mass, often
associated with brain infections or infarcts?
A. Liquefactive necrosis
,B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Answer: A
Conceptual Explanation: Liquefactive necrosis occurs when dead cells liquefy due to the
release of lysosomal enzymes; it is typical in brain damage or bacterial infections resulting
in pus.
3. What is the primary chemical mediator released from mast cells immediately during an
inflammatory response that causes vasodilation?
A. Prostaglandins
B. Bradykinin
C. Histamine
D. Leukotrienes
Answer: C
Conceptual Explanation: Histamine is released immediately from mast cell granules,
leading to increased capillary permeability and vasodilation.
4. In the TNM cancer staging system, what does ‘N’ stand for?
A. Number of tumors
B. Neoplasm grade
, C. Involvement of regional lymph nodes
D. Necrosis level
Answer: C
Conceptual Explanation: In the TNM system, T is for Tumor size, N is for regional lymph
Node involvement, and M is for Metastasis.
5. Which condition is characterized by a decrease in pH and an increase in CO2 levels, often
caused by hypoventilation?
A. Metabolic acidosis
B. Respiratory acidosis
C. Respiratory alkalosis
D. Metabolic alkalosis
Answer: B
Conceptual Explanation: Respiratory acidosis occurs when the lungs cannot remove
enough CO2, causing the blood pH to drop.
6. A patient presents with ‘moon face,’ ‘buffalo hump,’ and hypertension. These clinical
manifestations are typical of:
A. Cushing’s syndrome
B. Diabetes insipidus
C. Addison’s disease
