,Q1. In a 60-year-old with new-onset dyspnea, which pathophysiological mechanism
most directly explains the early reduction in diffusing capacity of the lungs for carbon
monoxide (DLCO) observed in pulmonary fibrosis?
A. Alveolar wall thickening and destruction of the capillary bed
B. Increased pulmonary capillary blood volume due to left heart failure
C. Airway obstruction causing ventilation-perfusion mismatch
D. Reduced respiratory drive from central chemoreceptor insensitivity
Correct Answer: A. Alveolar wall thickening and destruction of the capillary bed
Rationale: In pulmonary fibrosis, thickening of the alveolar-capillary membrane and loss
of pulmonary capillaries impede gas transfer, reducing DLCO. Increased capillary volume
(B) would increase DLCO; airway obstruction (C) primarily affects FEV1/FVC; central
drive (D) does not affect DLCO.
Why Wrong:
B - Increased capillary volume actually increases DLCO, not reduces it.
C - Airway obstruction affects flow rates, not DLCO directly.
D - Central chemoreceptor insensitivity affects ventilation, not gas diffusion.

for Disease in Adults and Children, 9th ed., Ch. 35.
Q2. Which finding on a chest radiograph is most indicative of pulmonary
hypertension in the setting of chronic obstructive pulmonary disease (COPD)?
A. Hyperlucency of the lung fields and flattened diaphragms
B. Enlarged central pulmonary arteries with peripheral pruning
C. Air bronchograms in the right middle lobe
D. Blunting of the costophrenic angles with Kerley B lines
Correct Answer: B. Enlarged central pulmonary arteries with peripheral pruning
Rationale: Pulmonary hypertension (PH) on CXR shows enlarged hilar pulmonary
arteries (16 mm) with rapid tapering (pruning) of peripheral vessels. Hyperlucency (A)
indicates hyperinflation, air bronchograms (C) suggest consolidation, and Kerley B lines
(D) point to interstitial edema.
Why Wrong:
A - Hyperlucency and flattened diaphragms are signs of hyperinflation, not PH.
C - Air bronchograms are seen in airspace opacification, not PH.
D - Kerley B lines are classic for interstitial edema, not PH.

, Q3. A 60-year-old presents with progressive dyspnea and a dry cough. Spirometry
shows FEV1/FVC of 0.78, FEV1 62% predicted, and DLCO 45% predicted. Which
additional test would best differentiate between interstitial lung disease (ILD) and
chronic heart failure (HF)?
A. Brain natriuretic peptide (BNP) level
B. High-resolution computed tomography (HRCT) of the chest
C. Echocardiogram with Doppler
D. Arterial blood gas (ABG) analysis
Correct Answer: B. High-resolution computed tomography (HRCT) of the chest
Rationale: HRCT is the gold standard for identifying ILD patterns (reticulation,
honeycombing), while HF typically shows septal thickening and ground-glass opacities.
BNP (A) can be elevated in both, echocardiogram (C) may show diastolic dysfunction but
not ILD, and ABG (D) is nonspecific.
Why Wrong:
A - BNP is elevated in HF but also can be mildly elevated in ILD due to right heart
strain.
C - Echocardiogram assesses cardiac function but does not directly visualize lung
parenchyma.
D - ABG reflects gas exchange but cannot distinguish ILD from HF.

Progressive Pulmonary Fibrosis in Adults: An Official ATS/ERS/JRS/ALAT
Clinical Practice Guideline. Am J Respir Crit Care Med, 205(9), e18-e47.
Q4. For a 60-year-old with acute decompensated heart failure and respiratory
distress, which prescription is most appropriate to administer first?
A. IV furosemide 40 mg bolus
B. Sublingual nitroglycerin 0.4 mg
C. IV metoprolol 5 mg over 2 minutes
D. Oral hydralazine 25 mg
Correct Answer: B. Sublingual nitroglycerin 0.4 mg
Rationale: In acute pulmonary edema with respiratory distress, preload reduction with
sublingual nitroglycerin provides rapid symptomatic relief. Furosemide (A) is important
but slower; metoprolol (C) is contraindicated in acute decompensation; hydralazine (D) is
not first-line.
Why Wrong:
A - Furosemide is appropriate but its onset is slower; nitroglycerin acts faster.
C - Beta-blockers are contraindicated in acute decompensated HF.
D - Hydralazine is used for chronic hypertension, not acute pulmonary edema.
