1. A patient with type 2 diabetes develops nephropathy. The
earliest clinical sign of diabetic nephropathy is:
A. Elevated serum creatinine
B. Microalbuminuria (30–300 mg/24 hours)
C. Gross hematuria
D. Decreased glomerular filtration rate (GFR)
Correct Answer: B
Rationale: Microalbuminuria is the earliest detectable sign of
diabetic nephropathy, appearing before a decline in GFR or
elevation in serum creatinine.

,2. In heart failure with reduced ejection fraction (HFrEF), the
compensatory mechanism that initially increases cardiac
output but eventually worsens outcomes is:
A. Vasodilation
B. Activation of the renin-angiotensin-aldosterone system (RAAS)
and sympathetic nervous system
C. Increased natriuretic peptides
D. Bradycardia
Correct Answer: B
Rationale: RAAS and sympathetic activation increase preload,
afterload, and contractility initially but lead to ventricular
remodeling, fibrosis, and worsening failure over time.
3. A patient with cirrhosis develops ascites. The primary
pathophysiologic mechanism is:
A. Decreased aldosterone
2
,B. Portal hypertension leading to splanchnic vasodilation and
sodium retention
C. Increased serum albumin
D. Decreased antidiuretic hormone (ADH)
Correct Answer: B
Rationale: Portal hypertension causes splanchnic vasodilation →
effective arterial blood volume decrease → RAAS activation →
sodium and water retention → ascites.
4. The pathognomonic finding in multiple myeloma is:
A. Reed-Sternberg cells
B. M protein (monoclonal gammopathy) on serum protein
electrophoresis
C. Philadelphia chromosome
D. Auer rods
3
, Correct Answer: B
Rationale: M protein (monoclonal immunoglobulin) is the hallmark
of multiple myeloma. Reed-Sternberg cells are in Hodgkin
lymphoma; Philadelphia chromosome in CML; Auer rods in AML.
5. A patient with chronic obstructive pulmonary disease
(COPD) develops hypercapnia. The primary mechanism is:
A. Increased oxygen consumption
B. Ventilation-perfusion (V/Q) mismatch and increased dead
space ventilation
C. Diffusion limitation only
D. Anemia
Correct Answer: B
Rationale: In severe COPD, V/Q mismatch and increased dead
space impair CO2 elimination. Hypercapnia occurs when
compensatory mechanisms fail.
