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

Choice A rationale In patients with leukemia, thrombocytopenia is a major risk factor for spontaneous and life-threatening hemorrhage. The normal platelet range is 150,000 to 400,000/mm. A value of 125,000/mm is below the normal limit and indicates a high risk for bleeding, making it the highest priority for the nurse to monitor. Although not severely low, any reduction in platelets in a leukemia patient signals bone marrow suppression that requires immediate clinical attention. Choice B rationale This symptom is common in leukemia due to the rapid expansion of the bone marrow by malignant cells, which increases intramedullary pressure. While bone pain is distressing and requires effective pain management, it is not immediately life-threatening compared to the risks associated with hematological instabilities like severe bleeding or infection. Therefore, it is a lower priority than a low platelet count when using the ABC or safety framework for nursing prioritization. Choice C rationale The hematocrit level measures the volume percentage of red blood cells in the blood. The normal range for adults is approximately 37 to 52 percent depending on sex. A value of 35 percent indicates mild anemia, which is expected in leukemia due to marrow overcrowding. While it causes fatigue and requires monitoring, it does not pose an immediate physiological threat as urgent as the potential for hemorrhage associated with low platelet levels. Choice D rationale Weight loss is a systemic manifestation of the hypermetabolic state associated with malignancy and the side effects of chemotherapy. Although nutritional status is important for long-term recovery and immune function, it is a chronic finding. In the acute setting of leukemia data collection, physical safety risks such as bleeding or sepsis take precedence over the gradual changes in body weight or nutritional intake and metabolic consumption.
