,Q1. Which integrin on neutrophils binds to ICAM-1 on endothelium during firm
adhesion in the inflammatory response?
A. L-selectin
B. CD11/CD18 (2 integrin)
C. P-selectin
D. E-selectin
Correct Answer: B. CD11/CD18 (2 integrin)
Rationale: Firm adhesion of neutrophils to endothelium is mediated by ²2 integrins
(CD11/CD18) binding to ICAM-1. L-selectin, P-selectin, and E-selectin are involved in
rolling adhesion, not firm adhesion.
Why Wrong:
A - L-selectin mediates rolling, not firm adhesion.
C - P-selectin is involved in initial rolling, not firm adhesion.
D - E-selectin also mediates rolling, not firm adhesion.

Disease. 10th ed. Elsevier; 2021. Ch. 3.
Q2. Which reactive oxygen species is most directly responsible for DNA strand breaks
during reperfusion injury?
A. Superoxide anion
B. Hydrogen peroxide
C. Hydroxyl radical
D. Nitric oxide
Correct Answer: C. Hydroxyl radical
Rationale: The hydroxyl radical (•OH) is highly reactive and directly oxidizes DNA bases
causing strand breaks. Superoxide and hydrogen peroxide are less reactive; nitric oxide
may combine with superoxide but is not primary for DNA breakage.
Why Wrong:
A - Superoxide is less reactive and does not directly cause DNA strand breaks.
B - Hydrogen peroxide is relatively stable and requires conversion to -OH to damage
DNA.
D - Nitric oxide primarily acts as a signaling molecule and vasodilator; it does not
directly cause DNA strand breaks.

Q3. Loss of function of the retinoblastoma (Rb) gene leads to unregulated cell cycle
progression because Rb normally:
A. Inhibits cyclin D-CDK4/6 complex
B. Binds and inhibits E2F transcription factors
Page 3
, C. Activates p53
D. Promotes apoptosis
Correct Answer: B. Binds and inhibits E2F transcription factors
Rationale: Rb binds E2F, preventing transcription of genes required for S-phase entry.
Loss of Rb releases E2F, allowing cell cycle progression. Rb does not directly inhibit
cyclin-CDK complexes, activate p53, or promote apoptosis.
Why Wrong:
A - p16 inhibits cyclin D-CDK4/6, not Rb.
C - p53 is activated by DNA damage, not directly by Rb.
D - Rb suppresses cell cycle; its loss promotes proliferation, not apoptosis.

Disease. 10th ed. Elsevier; 2021. Ch. 7.
Q4. A patient with right-sided heart failure develops pitting edema in the lower
extremities. The primary mechanism of this edema is:
A. Decreased plasma oncotic pressure
B. Increased capillary hydrostatic pressure
C. Lymphatic obstruction
D. Increased capillary permeability
Correct Answer: B. Increased capillary hydrostatic pressure
Rationale: Right-sided heart failure increases venous pressure, raising capillary
hydrostatic pressure, which drives fluid into the interstitium. Decreased oncotic pressure
occurs in nephrotic syndrome; lymphatic obstruction in lymphedema; increased
permeability in inflammation.
Why Wrong:
A - Decreased oncotic pressure is seen in hypoalbuminemia, not typical of heart
failure.
C - Lymphatic obstruction causes lymphedema, not related to heart failure.
D - Increased capillary permeability occurs in inflammation, not primarily in heart
failure.
Reference: Kumar V, Abbas AK, Aster JC. Robbins and Cotran Pathologic Basis of
Disease. 10th ed. Elsevier; 2021. Ch. 4.
Q5. In the early stage of septic shock, the typical hemodynamic change is:
A. Increased systemic vascular resistance
B. Decreased cardiac output
C. Decreased systemic vascular resistance
D. Increased capillary permeability
