A client with suspected leukemia is undergoing a cytogenetic analysis. What is the primary goal of this test in the diagnostic evaluation of leukemia?
Assess the client's immune response
Determine the client's blood type
Identify specific genetic abnormalities in the leukemic cells
Evaluate the client's liver function
The Correct Answer is C
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.

Correct Answer is C
Explanation
A) This choice is incorrect because CLL specifically involves the overproduction of abnormal lymphocytes, not myeloid cells. Myeloid cells are affected in other types of leukemia, such as AML.
B) This choice is incorrect because CLL is a chronic and indolent type of leukemia. It has a slow onset and progresses slowly over time, unlike some other leukemias that may have a more rapid course.
C) This choice is correct. In CLL, abnormal lymphocytes, mainly B-lymphocytes, accumulate in the bone marrow and interfere with the production of other blood cells, including red blood cells, platelets, and other white blood cells.
D) This choice is incorrect because CLL does not involve a genetic mutation leading to uncontrolled growth of red blood cells. That description is more characteristic of polycythemia vera, a different type of blood disorder.
Correct Answer is B
Explanation
A) This choice is incorrect because assessing bone density and strength is not the primary purpose of a CT scan in the diagnostic evaluation of leukemia.
B) This choice is correct. A CT scan is commonly used to identify enlarged lymph nodes and organs, which can occur in leukemia as a result of cancerous cell proliferation and infiltration into the lymphatic system and other organs.
C) This choice is incorrect because measuring lung capacity is not the primary purpose of a CT scan in the diagnostic evaluation of leukemia.
D) This choice is incorrect because monitoring cardiac function is not the primary goal of a CT scan in the diagnostic evaluation of leukemia.
