Which laboratory value should the nurse report for a client receiving cyclophosphamide?

In patients receiving cyclophosphamide, a chemotherapy agent known for its potential to cause myelosuppression, monitoring blood cell counts is crucial. The significant lab value that stands out is the platelet count of 40,000 mm3.

A normal platelet count ranges from approximately 150,000 to 450,000 mm3. A platelet count of 40,000 mm3 is indicative of thrombocytopenia, which increases the risk of bleeding complications. This condition can be particularly concerning for patients undergoing treatment with cyclophosphamide, as the medication can severely hinder the bone marrow's ability to produce platelets.

In contrast, the other laboratory values do not indicate an immediate concern in this context. A hemoglobin level of 12 g/dL is typically within the normal range for many adults, and while monitoring for potential drops during treatment is important, it is not immediately alarming. Potassium and sodium levels mentioned in the options are also within normal ranges, making them less critical to report in regard to the risks associated with cyclophosphamide therapy. Therefore, the drop in platelet count should be reported promptly to ensure appropriate management of the patient's treatment plan and prevent complications.
