,Q1. In a patient with chronic heart failure, which compensatory mechanism initially
preserves cardiac output but ultimately contributes to disease progression?
A. Activation of the renin-angiotensin-aldosterone system (RAAS)
B. Increased atrial natriuretic peptide (ANP) secretion
C. Downregulation of beta-adrenergic receptors
D. Enhanced peripheral vasodilation
Correct Answer: A. Activation of the renin-angiotensin-aldosterone system (RAAS)
Rationale: RAAS activation initially increases preload and contractility, but chronic
activation leads to adverse remodeling, fibrosis, and fluid retention, worsening heart
failure. ANP opposes RAAS, receptor downregulation is maladaptive, and vasodilation
would worsen hypotension.
Why Wrong:
B - ANP is a compensatory counter-regulatory hormone, not a primary maladaptive
mechanism.
C - Beta-receptor downregulation is a consequence, not an initial compensatory
mechanism that preserves output.
D - Peripheral vasodilation would reduce afterload but is not the primary
neurohormonal compensatory response.

Q2. Which genetic mutation is most directly associated with the development of
familial adenomatous polyposis (FAP) and colorectal cancer?
A. BRCA1
B. APC
C. p53
D. KRAS
Correct Answer: B. APC
Rationale: APC is a tumor suppressor gene; its mutation leads to uncontrolled Wnt
signaling and accumulation of beta-catenin, initiating colorectal adenomas. BRCA1 is
linked to breast/ovarian cancer, p53 mutations are later events, KRAS is an oncogene
involved in progression.
Why Wrong:
A - BRCA1 is primarily associated with breast and ovarian cancers, not colorectal
polyposis.
C - p53 mutations occur later in colorectal carcinogenesis, not as the initiating
germline defect in FAP.
D - KRAS is an oncogene mutated in ~40% of colorectal cancers but not the germline
cause of FAP.

Q3. In acute respiratory distress syndrome (ARDS), the primary mechanism of
hypoxemia is:
A. Hypoventilation
B. Right-to-left intrapulmonary shunting
C. Diffusion impairment
D. Ventilation-perfusion mismatch
Correct Answer: B. Right-to-left intrapulmonary shunting
Rationale: ARDS is characterized by alveolar flooding and collapse, leading to true shunt
(blood perfusing non-ventilated alveoli) that is refractory to supplemental oxygen.
Hypoventilation and diffusion impairment are less prominent, and V/Q mismatch, though
present, is not the primary cause of refractory hypoxemia.
Why Wrong:
A - Hypoventilation causes hypercapnia, but ARDS hypoxemia is primarily due to
shunt, not global hypoventilation.
C - Diffusion impairment is not the dominant mechanism; alveolar filling causes
shunt.
D - V/Q mismatch can be corrected with oxygen, unlike the shunt component in
ARDS.

Q4. Which of the following best explains the pathophysiology of type 2 diabetes
mellitus (T2DM) in the context of insulin resistance?
A. Autoimmune destruction of pancreatic beta cells
B. Impaired insulin signaling due to defective insulin receptor substrate (IRS)
phosphorylation
C. Genetic deficiency of the insulin gene
D. Excessive insulin secretion leading to receptor downregulation
Correct Answer: B. Impaired insulin signaling due to defective insulin receptor
substrate (IRS) phosphorylation
Rationale: In T2DM, insulin resistance arises from defects in insulin signaling, including
impaired IRS-1 phosphorylation and downstream PI3K/Akt pathway activation.
Autoimmune destruction is T1DM, insulin gene deficiency is rare, and hyperinsulinemia is
compensatory, not a primary cause.
Why Wrong:
A - Autoimmune destruction of beta cells is characteristic of type 1 diabetes, not
T2DM.
