A client with leukemia is undergoing a bone marrow biopsy for diagnosis and staging. The nurse should explain that the primary purpose of this procedure is to:

A) This choice is incorrect because leukemia does not lead to the increased production of normal red blood cells. Instead, it causes the overproduction of abnormal white blood cells.

B) This choice is incorrect because leukemia does not lead to the accumulation of normal platelets in the blood. Thrombocytopenia, or low platelet count, is common in leukemia due to the suppression of normal platelet production in the bone marrow.

C) This choice is correct. In leukemia, the proliferation of abnormal white blood cells crowds out and suppresses the normal bone marrow stem cells responsible for producing red blood cells, platelets, and other white blood cells. This suppression leads to anemia and thrombocytopenia.

D) This choice is incorrect because while cancerous cells may infiltrate healthy tissues in other types of cancer, leukemia primarily affects the bone marrow and blood, not other organs or tissues.

A) This choice is incorrect because AML is not characterized by the overproduction of immature lymphocytes. It involves the uncontrolled proliferation of abnormal myeloid cells in the bone marrow.

B) This choice is incorrect because AML does not cause abnormal proliferation of red blood cells. Anemia may occur as a result of AML due to the displacement of normal blood-forming cells in the bone marrow.

C) This choice is correct. AML is a type of leukemia that arises from genetic mutations in the myeloid stem cells. These mutations lead to uncontrolled growth and accumulation of abnormal myeloid cells, including granulocytes, monocytes, and platelets.

D) This choice is incorrect because the abnormal growth of plasma cells leading to the production of abnormal antibodies is characteristic of multiple myeloma, not AML.
