Final answer:
The lab value to report for a hemodialysis patient with end-stage kidney disease is Sodium 148 mEq/L, indicating hypernatremia.
Step-by-step explanation:
The laboratory value that should be reported to the provider for a client who has end-stage kidney disease and received hemodialysis 24 hours ago is D) Sodium 148 mEq/L. A normal sodium level is generally between 135 to 145 mEq/L. A sodium level of 148 mEq/L is indicative of hypernatremia, which can be associated with dehydration and must be addressed in patients with renal issues. Platelet count, calcium levels, and white blood cell count listed in the other options are within normal ranges and would not generally be a cause for immediate concern following hemodialysis.
