Which physical examination finding is most consistent with cardiogenic pleural effusion?

• A. Displaced Apical Pulse
• B. Hyperactive Bowel Sounds
• C. Distinct Bronchial Breath Sounds at Bases
• D. Pitting Edema Without Chest Findings

Answer: (A)

Cardiogenic pleural effusion is driven by heart failure, which often leads to an enlarged, or dilated, heart. When the heart enlarges, the point of maximal impulse (apical impulse) shifts laterally on the chest wall. This displaced apical pulse is a classic sign of cardiomegaly and points toward a cardiogenic cause for the pleural effusion. The other findings don’t fit as well: hyperactive bowel sounds are unrelated to the chest, distinct bronchial breath sounds at the bases suggest airway or parenchymal pathology rather than a pleural effusion, and while edema can accompany heart failure, pitting edema without chest findings does not indicate a pleural effusion or its cardiogenic origin.
