In a patient with suspected cardiogenic shock, which lung auscultation finding is most consistent with pulmonary edema?

In a patient with suspected cardiogenic shock, which lung auscultation finding is most consistent with pulmonary edema?

• A. Absence of crackles
• B. Clear lungs
• C. Crackles at lung bases
• D. Wheezing only

Answer: (C)

Pulmonary edema from cardiogenic shock causes fluid to accumulate in the alveolar spaces. This fluid change creates crackling sounds when air moves through the fluid-filled airways, best heard at the bases where gravity concentrates edema early on. So hearing crackles at the lung bases is the classic auscultatory sign of edema in this context. Absence of crackles or clear lungs would argue against edema, while wheezing alone points more toward bronchospasm or reactive airways disease rather than the fluid buildup seen in pulmonary edema.
