In a patient with renal failure who missed dialysis, which finding would most strongly support fluid overload?

Fluid overload from missed dialysis most clearly shows up as fluid in the lungs, i.e., pulmonary edema. When the kidneys aren’t removing enough fluid, extra volume raises pressure in the pulmonary capillaries and fluid leaks into the interstitial spaces and alveoli. That accumulation produces crackles heard at the bases of the lungs. So basilar rales are a direct, strong sign of pulmonary edema and fluid overload. Clear lungs would argue against edema, a normal blood pressure doesn’t rule out overload, and hyponatremia is an electrolyte issue rather than a direct indicator of excess fluid in the lungs.
