1. Which cellular adaptation is characterized by the replacement of one mature cell type by
another mature cell type, often in response to chronic irritation?
A. Anaplasia
B. Hypertrophy
C. Dysplasia
D. Metaplasia
Answer: D
Conceptual Explanation: Metaplasia is a reversible change in which one adult cell type is
replaced by another adult cell type to better withstand adverse environmental conditions.
2. A patient presents with a serum potassium level of 6.2 mEq/L. Which of the following
electrocardiogram (ECG) changes is most characteristic of this condition?
A. Prominent U waves
B. Tall, peaked T waves
,C. Prolonged QT interval
D. ST-segment depression
Answer: B
Conceptual Explanation: Hyperkalemia (high serum potassium) typically manifests on an
ECG as tall, peaked T waves due to faster repolarization of the cardiac muscle.
3. In the context of acid-base balance, how does the body compensate for metabolic acidosis?
A. Decreasing the rate and depth of respiration
B. Increasing the secretion of hydrogen ions by the kidneys
C. Increasing the reabsorption of chloride ions
D. Decreasing the production of bicarbonate ions
Answer: B
Conceptual Explanation: To compensate for metabolic acidosis, the kidneys increase the
secretion of H+ ions and increase the reabsorption of bicarbonate to raise the blood pH.
4. Which chemical mediator is primarily responsible for the immediate vasodilation and
increased capillary permeability during the acute inflammatory response?
A. Leukotrienes
B. Prostaglandins
C. Cytokines
, D. Histamine
Answer: D
Conceptual Explanation: Histamine is released immediately from mast cell granules,
causing rapid vasodilation and increased permeability of the capillaries.
5. What is the primary difference between a keloid and a hypertrophic scar?
A. Keloids are more likely to regress over time.
B. Hypertrophic scars contain more collagen than keloids.
C. Keloids extend beyond the original boundaries of the wound.
D. Hypertrophic scars occur only in dark-skinned individuals.
Answer: C
Conceptual Explanation: Keloids are characterized by an overgrowth of scar tissue that
extends beyond the initial site of injury, unlike hypertrophic scars which stay within the
wound boundaries.
6. Which type of hypersensitivity reaction is mediated by IgE antibodies binding to mast cells,
leading to the release of histamine?
B. Type IV Hypersensitivity
A. Type II Hypersensitivity
C. Type III Hypersensitivity
D. Type I Hypersensitivity
