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.
