A nurse is reviewing the laboratory results of a group of clients. Which of the following laboratory findings should the nurse report to the provider?

A. Hemoglobin of 6.2 g/dL in a client who is receiving chemotherapy: Hgb 6.2 g/dL is severely low and may require urgent intervention (transfusion, evaluation for bleeding or marrow suppression), especially in a chemo patient. B. WBC of 7,000/mm³ in a client who has a non-productive cough: WBC 7,000 is within normal limits (≈4,500–11,000) and not necessarily reportable by itself. C. Platelet count of 160,000/mm³ in a client who has a DVT and is taking enoxaparin: 160,000 is within the normal platelet range (150,000–400,000) and not an immediate concern. D. Negative leukocyte esterase in a client who has completed antibiotics for a UTI: Negative leukocyte esterase suggests resolution of infection and is not a reportable abnormality.
