QUESTIONS AND ANSWERS
1. A patient exhibits a replacement of normal squamous epithelial cells with columnar
epithelial cells in the lower esophagus due to chronic acid reflux. This cellular adaptation is
known as:
A. Metaplasia
B. Hyperplasia
C. Dysplasia
D. Anaplasia
Answer: A
Conceptual Explanation: Metaplasia is the reversible replacement of one mature cell type
by another, often in response to chronic irritation.
,2. Which mechanism is primarily responsible for the development of edema in a patient with
nephrotic syndrome?
A. Increased capillary hydrostatic pressure
B. Lymphatic obstruction
C. Increased capillary permeability
D. Decreased capillary oncotic pressure
Answer: D
Conceptual Explanation: Nephrotic syndrome involves significant protein loss in urine,
leading to hypoalbuminemia and decreased plasma oncotic pressure, which allows fluid to
leak into the interstitium.
3. Which genetic condition is characterized by a 45,X karyotype?
A. Klinefelter syndrome
B. Down syndrome
C. Turner syndrome
D. Cri du chat syndrome
Answer: C
Conceptual Explanation: Turner syndrome is a chromosomal disorder in females where
one X chromosome is missing or partially missing.
, 4. In the context of pharmacokinetics, what does the term ‘first-pass effect’ describe?
A. The rapid excretion of a drug by the kidneys
B. The metabolism of an oral drug in the liver before reaching systemic circulation
C. The absorption of a drug through the blood-brain barrier
D. The binding of a drug to plasma proteins
Answer: B
Conceptual Explanation: The first-pass effect is the metabolism of a drug in the liver or
gut wall after oral administration, reducing the concentration before it reaches the
systemic circulation.
5. A patient with heart failure is prescribed an ACE inhibitor. What is the primary
hemodynamic effect of this drug?
A. Decreased afterload via vasodilation
B. Increased systemic vascular resistance
C. Increased heart rate and contractility
D. Increased sodium and water retention
Answer: A
Conceptual Explanation: ACE inhibitors block the conversion of Angiotensin I to
Angiotensin II, a potent vasoconstrictor, thereby reducing systemic vascular resistance
(afterload).
