A nurse is collecting data from a client who has leukemia. Which of the following findings has the highest priority?

A. A platelet count of 125,000/mm³ indicates thrombocytopenia, which increases the risk of bleeding. This is the highest priority because bleeding can be life-threatening. B. Hematocrit is slightly low, indicating mild anemia, but it is less immediately critical than the risk of bleeding from low platelets. C. Bone pain is a common symptom in leukemia due to marrow expansion but does not pose an immediate threat to life. D. Weight loss is a concerning chronic symptom but is not an immediate priority compared to bleeding risk.
