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:
Remove a tumor mass from the bone marrow.
Assess the presence of circulating cancer cells in the bloodstream.
Evaluate the overall blood cell count and differential.
Obtain a sample of bone marrow tissue for examination.
The Correct Answer is D
A) This choice is incorrect because a bone marrow biopsy is not performed to remove a tumor mass. The purpose of the procedure is to obtain a sample of bone marrow tissue for diagnostic evaluation.
B) This choice is incorrect because assessing the presence of circulating cancer cells in the bloodstream is typically done through a blood test, not a bone marrow biopsy. The biopsy provides direct information about the condition of the bone marrow.
C) This choice is incorrect because evaluating the overall blood cell count and differential is typically done through a complete blood count (CBC) test, not a bone marrow biopsy. The biopsy provides more detailed information about the bone marrow and its cellular composition.
D) This choice is correct. The primary purpose of a bone marrow biopsy is to obtain a sample of bone marrow tissue for examination under a microscope. This allows healthcare professionals to assess the presence of abnormal cells, determine the type and extent of leukemia, and guide treatment decisions.

Correct Answer is B
Explanation
A) This choice is incorrect because swollen lymph nodes are more characteristic of chronic leukemia, not acute leukemia like AML.
B) This choice is correct. Chronic lymphocytic leukemia (CLL) is commonly associated with enlarged lymph nodes due to the accumulation of abnormal lymphocytes in these areas. It is a slow-progressing leukemia and often presents with lymphadenopathy.
C) This choice is incorrect because while ALL may involve enlarged lymph nodes, it is more commonly associated with symptoms like fatigue, bleeding, and bone pain.
D) This choice is incorrect because while CML may present with enlarged spleen and liver, it is less likely to cause significant lymphadenopathy compared to CLL.
Correct Answer is C
Explanation
A) This choice is incorrect because a bone marrow biopsy is not primarily performed to assess the client's platelet count. Platelet counts are typically obtained through a blood test.
B) This choice is incorrect because evaluating the effectiveness of chemotherapy is not the primary reason for performing a bone marrow biopsy in the diagnostic evaluation of leukemia. The biopsy is performed to determine the presence of cancerous cells in the bone marrow and aid in diagnosing leukemia.
C) This choice is correct. A bone marrow biopsy involves the collection of bone marrow samples to determine the presence of cancerous cells and assess cell morphology in the bone marrow. This information is crucial in diagnosing leukemia and determining the appropriate treatment plan.
D) This choice is incorrect because measuring the client's bone density is not the primary reason for performing a bone marrow biopsy.
