1. A 55-year-old male smoker’s biopsy results indicate that the ciliated columnar epithelium
in the trachea has been replaced by stratified squamous epithelium. Which term best
describes this cellular adaptation?
A. Hyperplasia
B. Anaplasia
C. Dysplasia
D. Metaplasia
Answer: D
Conceptual Explanation: Metaplasia is the replacement of one mature cell type by another
mature cell type, often as a response to chronic irritation like smoking.
2. Which process is characterized by programmed cell death that does not typically trigger an
inflammatory response?
A. Necrosis
,B. Apoptosis
C. Liquefaction
D. Infarction
Answer: B
Conceptual Explanation: Apoptosis is a normal, programmed genetic process of cell self-
destruction that avoids the release of intracellular contents and subsequent inflammation.
3. A patient presents with severe dehydration and a serum sodium level of 155 mEq/L. Which
clinical manifestation is most likely expected?
A. Muscle weakness and twitching
B. Abdominal cramping
C. Agitation and restlessness
D. Hyporeflexia
Answer: C
Conceptual Explanation: Hypernatremia (Sodium > 145 mEq/L) typically causes CNS
irritability, agitation, and thirst as water shifts out of brain cells.
4. Which arterial blood gas (ABG) result is consistent with uncompensated metabolic
acidosis?
A. pH 7.32, PaCO2 50, HCO3 30
B. pH 7.50, PaCO2 30, HCO3 24
, C. pH 7.30, PaCO2 40, HCO3 18
D. pH 7.45, PaCO2 35, HCO3 22
Answer: C
Conceptual Explanation: Metabolic acidosis is identified by a low pH (<7.35) and a low
bicarbonate (<22 mEq/L). If PaCO2 is normal, it is uncompensated.
5. In the inflammatory response, which chemical mediator is primarily responsible for
increasing capillary permeability and vasodilation immediately following injury?
A. Leukotrienes
B. Histamine
C. Prostaglandins
D. Cytokines
Answer: B
Conceptual Explanation: Histamine is released by mast cells immediately after injury,
causing rapid vasodilation and increased capillary permeability.
6. Which type of exudate is thick, sticky, and has high cell and fibrin content, usually
indicating a more advanced inflammatory process?
A. Serous
B. Fibrinous
C. Purulent
