The nurse analyzes the laboratory values of a pediatric client with leukemia who is receiving chemotherapy. The nurse notes the following lab values: platelets 19,500/mcl (nl. 140,000-400,000/mcL), hemoglobin 11 g/dL (nl. 12-16 g/dL), white blood cell count 9,800/mcl (nl. 5,000-10,000/mcL). Based on these findings, which intervention should the nurse prioritize in the plan of care?

A. Monitoring for infection is important, but the white blood cell count is within normal limits, so it is not the immediate priority. B. Although the hemoglobin is slightly low, it is not critically low, so transfusion of packed red blood cells is not immediately necessary. C. Intravenous immunoglobulins are not indicated based on the current lab values. D. The platelet count is critically low, placing the client at high risk for bleeding. Initiating bleeding precautions is the priority to prevent hemorrhage.
