A nurse is explaining the purpose of a computed tomography (CT) scan to a client with suspected leukemia. What is the primary goal of a CT scan in the diagnostic evaluation of leukemia?
Assess bone density and strength
Identify enlarged lymph nodes and organs
Measure the client's lung capacity
Monitor the client's cardiac function
The Correct Answer is B
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.

Correct Answer is C
Explanation
A) This choice is incorrect because leukemia does not primarily affect the lymph nodes. It is a cancer of the blood and bone marrow, where abnormal white blood cells are produced.
B) This choice is incorrect because leukemia is not characterized by the overproduction of platelets. Platelets are involved in blood clotting, and their overproduction is not a feature of leukemia.
C) This choice is correct. Leukemia is a type of cancer characterized by the uncontrolled proliferation of abnormal white blood cells in the bone marrow. These abnormal cells then enter the bloodstream, crowding out healthy blood cells and impairing normal blood cell function.
D) This choice is incorrect because leukemia is not an autoimmune disorder. It is a cancerous condition involving abnormal white blood cell growth.
Correct Answer is C
Explanation
A) This choice is incorrect because flow cytometry analysis is not primarily used to assess the client's heart function.
B) This choice is incorrect because determining the client's blood type is not the primary purpose of flow cytometry analysis in the diagnostic evaluation of leukemia.
C) This choice is correct. Flow cytometry analysis is a specialized laboratory technique used to classify the type of leukemia and its subtype based on specific cell markers present on the surface of leukemic cells. This information helps guide the appropriate treatment plan.
D) This choice is incorrect because evaluating the client's kidney function is not the primary purpose of flow cytometry analysis in the diagnostic evaluation of leukemia.
