A nurse is reinforcing teaching with the parent of a school-age child who is undergoing testing for acute lymphoid leukemia (ALL). The nurse should inform the parent that the child will undergo which of the following tests to confirm the diagnosis?

Rationale: A. While spinal fluid analysis may be necessary in some cases, it is not typically used to confirm a diagnosis of acute lymphoid leukemia (ALL). B. A complete blood count (CBC) may show abnormalities suggestive of leukemia, but it is not definitive for diagnosis. C. Bone marrow biopsy is necessary to confirm the diagnosis of acute lymphoid leukemia (ALL) by examining the bone marrow for abnormal cells. D. Bleeding time is not typically used to diagnose acute lymphoid leukemia (ALL); it assesses platelet function.
