Which finding would be of concern for fluid volume overload in a elderly patient receiving IV fluids at 125 mL/hr?

• A. Anxiety
• B. Crackles noted in the bases of the lungs
• C. CVP 5 mmHg
• D. S3 heart sound

Answer: (B)

Recognizing signs of fluid volume overload from IV fluids is crucial, especially in an elderly patient whose heart and kidneys may not handle extra volume well. Crackles at the bases of the lungs reflect pulmonary interstitial edema from excess intravascular fluid seeping into the lung tissue, signaling that the fluid administration may be overwhelming the circulation. This pulmonary edema is a direct, clinically important consequence of overload and can lead to shortness of breath and worsened oxygenation if not addressed. A central venous pressure of 5 mmHg sits within the normal range, so it doesn’t indicate overload. Anxiety is nonspecific and not a reliable sign of fluid overload. An S3 heart sound can be associated with increased filling pressures, but it is less specific and does not alone demonstrate lung edema like crackles do.
