Which finding is most consistent with fluid volume excess?

Which finding is most consistent with fluid volume excess?

• A. Weight gain
• B. Weight loss
• C. Dry mucous membranes
• D. Increased respiratory rate with edema

Answer: (A)

When the body has too much fluid, the extracellular space expands and overall body weight increases. The most consistent sign of fluid volume excess is weight gain because it directly reflects the added fluid in the body. Daily weights are a practical way to monitor fluid status and detect shifts early. Edema often accompanies fluid overload, and you may see pulmonary symptoms like shortness of breath if fluids accumulate in the lungs, but weight gain remains the most reliable single indicator of excess fluid. Weight loss and dry mucous membranes point to fluid deficit, not excess, and an increased respiratory rate with edema can occur but is not as specific or consistent as weight gain.
