Which finding is most consistent with fluid volume overload in this patient?

• A. Edema in the extremities
• B. Normal urine output
• C. Clear lungs without crackles
• D. Hypotension

Answer: (A)

Fluid volume overload means there’s too much fluid in the body’s circulating and interstitial spaces. The most visible and reliable sign is edema in the extremities, because excess fluid pushes into the interstitial tissues, leading to swelling in the legs and arms. This happens as venous pressure and capillary hydrostatic pressure rise, driving fluid out of vessels into surrounding tissues. Other options don’t fit as well. Normal urine output can occur with overload if the kidneys are still functioning, but it doesn’t reflect excess fluid. Clear lungs without crackles would argue against pulmonary edema, which often accompanies overload. Hypotension points more toward low circulating volume rather than excess. So peripheral edema best indicates there’s too much fluid.
