A nurse is preparing a client for a bone marrow biopsy. What is the primary reason for performing a bone marrow biopsy in the diagnostic evaluation of leukemia?
Assessing the client's platelet count
Evaluating the effectiveness of chemotherapy
Determining the presence of cancerous cells in the bone marrow
Measuring the client's bone density
The Correct Answer is C
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.

Correct Answer is C
Explanation
A) This choice is incorrect because a cytogenetic analysis is not primarily used to assess the client's immune response.
B) This choice is incorrect because determining the client's blood type is not the primary goal of a cytogenetic analysis in the diagnostic evaluation of leukemia.
C) This choice is correct. Cytogenetic analysis is a laboratory test that identifies specific genetic abnormalities, such as chromosomal rearrangements, deletions, or mutations, in the leukemic cells. These genetic findings are essential for diagnosing specific types of leukemia, determining prognosis, and guiding treatment decisions.
D) This choice is incorrect because evaluating the client's liver function is not the primary goal of a cytogenetic analysis in the diagnostic evaluation of leukemia.
Questions
Correct Answer is D
Explanation
A) This choice is incorrect because a history of frequent dental cavities is not a known risk factor for leukemia.
B) This choice is incorrect because allergies to pollen and pet dander are not associated with an increased risk of leukemia.
C) This choice is incorrect because recurrent urinary tract infections are not known to be a risk factor for leukemia.
D) This choice is correct. Previous treatment with chemotherapy and radiation is a significant risk factor for developing leukemia. Certain chemotherapeutic agents and radiation therapy can damage healthy blood-forming cells in the bone marrow, potentially leading to the development of leukemia later on. This type of leukemia is often referred to as secondary or treatment-related leukemia.
