On physical examination, which combination of findings suggests fluid overload in heart failure?

• A. S3 heart sound with elevated JVP
• B. S4 gallop with no edema
• C. Murmur of aortic stenosis
• D. Clear lungs without edema

Answer: (A)

Fluid overload from heart failure raises filling pressures and causes systemic venous congestion. An S3 heart sound is the extra beat that happens with rapid ventricular filling into a dilated, failing ventricle and reflects increased volume and reduced ventricular compliance. Elevated JVP shows high right-sided filling pressures and venous congestion. Together, these findings point to excess fluid in the circulation and congested heart failure, which is the essence of fluid overload.

The other patterns don’t fit as well. An S4 gallop indicates a stiff, noncompliant ventricle and is more about diastolic dysfunction than acute volume overload. A murmur of aortic stenosis points to a structural valve issue rather than fluid status. Clear lungs without edema suggests there isn’t pulmonary edema at that moment.
