,Q1. In a cell with a defective Na+/K+-ATPase pump, which of the following processes
would be MOST directly impaired?
A. Facilitated diffusion of glucose
B. Secondary active transport of calcium
C. Primary active transport of chloride
D. Simple diffusion of oxygen
Correct Answer: B. Secondary active transport of calcium
Rationale: The Na+/K+-ATPase maintains the sodium gradient, which drives secondary
active transport (e.g., Na+/Ca2+ exchanger). Without it, this gradient dissipates,
impairing secondary transport. Primary active transport of chloride (if any) uses its own
ATPase, and facilitated diffusion and simple diffusion are ATP-independent.
Why Wrong:
A - Facilitated diffusion relies on concentration gradients, not directly on the
Na+/K+-ATPase.
C - Primary active transport of chloride would use its own ATPase, not the
Na+/K+-ATPase.
D - Simple diffusion of oxygen is passive and independent of ATP or ion gradients.

Q2. A drug that inhibits the NLRP3 inflammasome would MOST directly reduce the
maturation of which cytokine?
A. TNF-
B. IL-1
C. IL-6
D. IFN-
Correct Answer: B. IL-1
Rationale: The NLRP3 inflammasome activates caspase-1, which cleaves pro-IL-1² into
its active form. TNF-, IL-6, and IFN- are not processed by this inflammasome.
Why Wrong:
A - TNF- is mainly regulated at the transcriptional level, not by inflammasome
cleavage.
C - IL-6 is not a substrate for caspase-1.
D - IFN- is produced by T cells and NK cells, not processed by the NLRP3
inflammasome.

, Q3. Which of the following best explains the increased risk of thrombosis in a patient
with antiphospholipid syndrome?
A. Antibodies inhibit protein C activation
B. Antibodies neutralize tissue factor pathway inhibitor
C. Antibodies cause platelet activation via Fc receptors
D. Antibodies enhance the activity of antithrombin III
Correct Answer: A. Antibodies inhibit protein C activation
Rationale: Antiphospholipid antibodies bind to phospholipids on endothelial cells and
platelets, interfering with the protein C pathway and reducing its anticoagulant function,
leading to a prothrombotic state. They do not directly neutralize TFPI or enhance
antithrombin III.
Why Wrong:
B - Antiphospholipid antibodies do not target TFPI.
C - While platelet activation may occur, the primary mechanism is inhibition of
natural anticoagulants like protein C.
D - They do not enhance antithrombin III activity.

Basis of Disease, 10th ed., Ch. 4
Q4. In a patient with chronic myeloid leukemia (CML) in the chronic phase, which
molecular abnormality is most directly responsible for the uncontrolled proliferation
of myeloid progenitors?
A. Activation of the JAK2-STAT pathway by a point mutation
B. Constitutive tyrosine kinase activity of the BCR-ABL1 fusion protein
C. Loss of function of the tumor suppressor p53
D. Overexpression of the anti-apoptotic protein Bcl-2
Correct Answer: B. Constitutive tyrosine kinase activity of the BCR-ABL1 fusion
protein
Rationale: CML is characterized by the Philadelphia chromosome, which creates the
BCR-ABL1 fusion gene encoding a constitutively active tyrosine kinase that drives
proliferation. JAK2 mutations are more common in myeloproliferative neoplasms like
polycythemia vera, not CML.
Why Wrong:
A - JAK2 mutations are not the primary driver in CML.
C - p53 loss is a later event in blast crisis, not the chronic phase.
D - Bcl-2 overexpression is not the hallmark of CML.
