A nurse is assessing a client who has end-stage kidney disease and is receiving hemodialysis. Which of the following findings should the nurse identify as an indication that the client is experiencing fluid overload?

A. Oxygen saturation of 93% may be slightly low but is not a definitive indicator of fluid overload on its own. B. A 5 lb. weight gain in 24 hours strongly suggests fluid retention, which is a key sign of fluid overload in dialysis clients. C. Flattened neck veins are more indicative of fluid volume deficit, not overload. D. Normal skin turgor (return of skin to normal position) does not indicate fluid overload.
