Which clinical sign suggests fluid overload in a patient with known congestive heart failure receiving IV fluids?

• A. Shortness of breath with crackles
• B. Normal lung sounds
• C. Clear breath sounds
• D. Decreased heart rate

Answer: (A)

Fluid overload in heart failure tends to produce pulmonary edema, where excess fluid pushes into the lungs and causes crackles as air moves through fluid-filled airways. When a patient with CHF on IV fluids experiences shortness of breath and has crackles on auscultation, that combination strongly indicates fluid overload and developing pulmonary edema. Normal or clear lung sounds argue against current fluid overload, and a decreased heart rate is not a reliable sign of excess fluid in this context.
