A nurse is assessing a client diagnosed with end-stage renal disease (ESRD) that is receiving hemodialysis. Which of the following findings should the nurse identify as an indication that the client is experiencing fluid overload?

A. Return of skin to previous position when the client's shin is palpated: This is a normal finding indicating no presence of edema. It suggests that skin turgor is within normal limits and does not point toward fluid overload in this context. B. Oxygen saturation 93%: While slightly lower than ideal, this level alone is not specific to fluid overload and can be seen in many conditions. Without respiratory distress or other signs, it is not definitive for volume excess. C. The client has gained 1 pound since yesterday: A 1-pound gain could indicate mild fluid retention, but in clients on hemodialysis, more significant weight changes are typically used to assess fluid accumulation. This gain is not a strong indicator of overload on its own. D. Distended neck veins: Jugular vein distension is a classic and reliable sign of fluid volume overload. It indicates elevated central venous pressure and is often seen in clients with ESRD experiencing excess intravascular fluid.
