,Q1. A patient with chronic heart failure develops worsening dyspnea and peripheral
edema. Which compensatory mechanism initially maintains cardiac output but
ultimately contributes to disease progression?
A. Activation of the renin-angiotensin-aldosterone system (RAAS)
B. Increased release of atrial natriuretic peptide (ANP)
C. Downregulation of beta-adrenergic receptors
D. Enhanced parasympathetic tone to the heart
Correct Answer: A. Activation of the renin-angiotensin-aldosterone system (RAAS)
Rationale: In heart failure, RAAS activation initially increases preload and maintains
cardiac output via sodium and water retention and vasoconstriction. However, chronic
activation leads to adverse remodeling, fibrosis, and worsening heart failure. ANP is
released in response to atrial stretch but is often overwhelmed; beta-receptor
downregulation is a consequence, not a compensatory mechanism; parasympathetic tone
is not enhanced.
Why Wrong:
B - ANP is a compensatory response but its effects are typically blunted in chronic
heart failure and it does not promote progression.
C - Beta-receptor downregulation is a maladaptive consequence of chronic
sympathetic stimulation, not an initial compensatory mechanism.
D - Parasympathetic tone is reduced in heart failure, not enhanced, to allow
sympathetic drive.

Q2. Which of the following best explains the pathophysiology of type 2 diabetes
mellitus (T2DM) in the context of the 'metabolic syndrome'?
A. Autoimmune destruction of pancreatic beta cells leading to absolute insulin
deficiency
B. Peripheral insulin resistance combined with progressive beta-cell dysfunction
C. Excessive glucagon secretion from alpha cells causing hyperglycemia
D. Impaired insulin signaling due to mutations in the insulin receptor gene
Correct Answer: B. Peripheral insulin resistance combined with progressive beta-cell
dysfunction
Rationale: T2DM is characterized by insulin resistance in muscle, liver, and adipose
tissue, coupled with a progressive decline in beta-cell function. This combination leads to
relative insulin deficiency and hyperglycemia. Type 1 diabetes involves autoimmune
beta-cell destruction; glucagon excess is a secondary abnormality; monogenic insulin
receptor mutations are rare and not the primary mechanism in metabolic syndrome.
Why Wrong:
A - This describes type 1 diabetes, not T2DM.
Page 3
, C - Glucagon dysregulation contributes but is not the primary pathophysiologic
defect.
D - Insulin receptor mutations cause rare syndromes like type A insulin resistance, not
typical T2DM.

Q3. A patient with a history of peptic ulcer disease is found to have a gastric ulcer.
Which of the following mechanisms is most likely contributing to the development of
this ulcer?
A. Hypersecretion of gastric acid due to a gastrinoma (Zollinger-Ellison syndrome)
B. Impaired mucosal defense due to Helicobacter pylori infection
C. Increased pepsinogen secretion from parietal cells
D. Bile reflux causing direct damage to the gastric mucosa
Correct Answer: B. Impaired mucosal defense due to Helicobacter pylori infection
Rationale: H. pylori infection is a major cause of gastric ulcers by disrupting the mucosal
barrier, leading to inflammation and increased susceptibility to acid damage.
Zollinger-Ellison syndrome causes duodenal ulcers more commonly; pepsinogen is
secreted by chief cells, not parietal cells; bile reflux is a contributory factor but not the
most common mechanism.
Why Wrong:
A - Zollinger-Ellison syndrome more often causes duodenal ulcers, not gastric ulcers.
C - Pepsinogen is secreted by chief cells, and hypersecretion is not a primary
mechanism.
D - Bile reflux can contribute but is not the most common cause of gastric ulcers.

Q4. Which of the following best describes the role of the JAK-STAT signaling
pathway in the pathophysiology of myeloproliferative neoplasms?
A. Activating mutations in JAK2 lead to constitutive activation of downstream
signaling, promoting unchecked myeloid proliferation.
B. Loss-of-function mutations in STAT proteins result in decreased hematopoiesis.
C. Overexpression of SOCS proteins enhances JAK-STAT signaling, contributing to
malignancy.
D. Inhibition of JAK2 by endogenous inhibitors causes cytopenias in these disorders.
Correct Answer: A. Activating mutations in JAK2 lead to constitutive activation of
downstream signaling, promoting unchecked myeloid proliferation.
Rationale: In myeloproliferative neoplasms (e.g., polycythemia vera), a somatic mutation
in JAK2 (V617F) leads to constitutive activation of the kinase, causing uncontrolled
