Which of the following laboratory findings would indicate a client is improving after treatment for hemolytic anemia?

A stabilized reticulocyte count is indicative of improvement in hemolytic anemia treatment because reticulocytes are immature red blood cells that are released into the bloodstream in response to anemia. In cases of hemolytic anemia, the body typically responds by producing more reticulocytes as it attempts to replace the red blood cells that are being destroyed.

As treatment progresses and the condition improves, the reticulocyte count should stabilize as the bone marrow adjusts to the reduction in hemolysis and the recovery of red blood cells occurs. A stable or normalized reticulocyte count suggests that the bone marrow is producing red blood cells at a rate appropriate for the body's needs, thus indicating an improvement in the overall condition.

In contrast, decreased hemoglobin and hematocrit would suggest worsening anemia, not improvement. A normal white blood cell count is not specific to hemolytic anemia recovery, as it does not reflect the status of red blood cell production or destruction. Likewise, increased C-reactive protein typically indicates inflammation and may not directly relate to improvements in hemolytic anemia, therefore not serving as an indicator of recovery in this context.
