SECTION A: MULTIPLE CHOICE QUESTIONS
Answer ALL questions. Each question carries 2 marks.
Total: 40 marks
Question 1:
A 68-year-old male with chronic heart failure presents with worsening dyspnea and
peripheral edema. His BNP is significantly elevated. Which pathophysiological
mechanism best explains the elevated BNP?
Options:
A) Increased ventricular wall stretch
B) Decreased renal perfusion
C) Sympathetic nervous system activation
D) Pulmonary hypertension
,Correct Answer: A
Marks: 2
Rationale:
BNP is released from ventricular myocardium in response to increased wall tension and
stretch. It serves as a compensatory mechanism to promote vasodilation and
natriuresis. Elevated BNP is a diagnostic and prognostic marker in heart failure.
Question 2:
A patient with type 2 diabetes has a fasting glucose of 8.2 mmol/L and HbA1c of 8.5%.
Which cellular mechanism primarily contributes to insulin resistance in skeletal muscle?
Options:
A) Defective GLUT4 translocation
B) Beta-cell apoptosis
C) Increased glucagon secretion
D) Decreased hepatic glycogenolysis
Correct Answer: A
Marks: 2
Rationale:
In type 2 diabetes, insulin resistance in skeletal muscle is primarily due to impaired
GLUT4 translocation to the plasma membrane. This reduces glucose uptake despite
normal or elevated insulin levels. The defect involves downstream insulin signaling
pathways including PI3K and Akt.
Question 3:
A 55-year-old female presents with sudden-onset right-sided weakness and aphasia. CT
imaging reveals a left middle cerebral artery territory infarct. Which pathophysiological
process is most likely responsible?
, Options:
A) Embolic occlusion
B) Lacunar infarction
C) Venous sinus thrombosis
D) Subarachnoid hemorrhage
Correct Answer: A
Marks: 2
Rationale:
Sudden-onset focal neurological deficits in a specific vascular territory strongly suggest
embolic occlusion. The middle cerebral artery is the most common site for
cardioembolic or large artery embolic strokes. Lacunar infarcts typically present with
pure motor or sensory deficits.
Question 4:
Which cytokine is most directly responsible for the systemic inflammatory response and
fever in sepsis?
Options:
A) Interleukin-6 (IL-6)
B) Interleukin-10 (IL-10)
C) Transforming growth factor-beta (TGF-β)
D) Interleukin-4 (IL-4)
Correct Answer: A
Marks: 2
Rationale:
IL-6 is a key pro-inflammatory cytokine mediating the acute phase response in sepsis,
including fever, hepatic acute phase protein synthesis, and systemic inflammation.
While TNF-alpha initiates the cascade, IL-6 sustains the systemic response.
