VERIFIED 2026/2027
1. Which term describes a reversible replacement of one mature adult cell type by another,
less mature adult cell type in response to chronic irritation?
A. Metaplasia
B. Hypertrophy
C. Atrophy
D. Dysplasia
Answer: A
Conceptual Explanation: Metaplasia is a reversible change where one differentiated cell
type is replaced by another to better withstand environmental stress.
2. During the inflammatory process, which chemical mediator is primarily responsible for
increasing capillary permeability and vasodilation immediately after injury?
A. Histamine
B. Platelet-activating factor
,C. Leukotrienes
D. Complement system
Answer: A
Conceptual Explanation: Histamine is released from mast cells early in the inflammatory
response, causing rapid vasodilation and increased permeability.
3. In the context of fluid balance, a patient with hyperaldosteronism would most likely exhibit
which of the following?
A. Decreased blood pressure
B. Hyperkalemia and hyponatremia
C. Excessive water loss through the kidneys
D. Increased serum sodium and decreased serum potassium
Answer: D
Conceptual Explanation: Aldosterone causes the kidneys to retain sodium and water
while excreting potassium, leading to hypernatremia and hypokalemia.
4. Which acid-base imbalance is a patient likely to experience if they have been vomiting
excessively for 24 hours?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
, D. Metabolic alkalosis
Answer: D
Conceptual Explanation: Vomiting causes a loss of hydrochloric acid from the stomach,
which results in a relative increase in bicarbonate in the blood.
5. Which type of hypersensitivity reaction involves the formation of antigen-antibody
complexes that deposit in tissue or blood vessel walls?
A. Type I (Immediate)
B. Type II (Cytotoxic)
C. Type IV (Delayed)
D. Type III (Immune Complex)
Answer: D
Conceptual Explanation: Type III reactions involve immune complexes that circulate and
deposit in tissues, triggering an inflammatory response like in SLE or glomerulonephritis.
6. What is the primary mechanism of action for the Human Immunodeficiency Virus (HIV) in
destroying the immune system?
A. Destruction of B-lymphocytes
B. Direct inhibition of the complement system
C. Infection and destruction of CD4+ T-helper cells
D. Neutralization of all circulating antibodies
