A nurse is explaining the role of radiation therapy in leukemia treatment to a client. What is the primary purpose of radiation therapy in leukemia treatment?
To replace damaged bone marrow with healthy stem cells
To induce remission and eliminate all leukemia cells
To target and destroy cancer cells in specific areas
To enhance the body's immune response against leukemia
The Correct Answer is C
A) This choice is incorrect because replacing damaged bone marrow with healthy stem cells is the primary goal of a stem cell transplant, not radiation therapy.
B) This choice is incorrect because while radiation therapy may be used to reduce the size of leukemia masses and induce remission in some cases, it is not typically used to eliminate all leukemia cells throughout the body.
C) This choice is correct. Radiation therapy is used to target and destroy cancer cells in specific areas where leukemia is localized, such as in the brain or other parts of the body. It can be used in combination with other treatment modalities.
D) This choice is incorrect because enhancing the body's immune response against leukemia is the goal of immunotherapy, not radiation therapy.

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.
Correct Answer is C
Explanation
A) This choice is incorrect because leukemia does not result from an overproduction of platelets. Leukemia involves an overproduction of abnormal white blood cells.
B) This choice is incorrect because leukemia is not caused by the body's immune system attacking healthy white blood cells. Instead, it involves the uncontrolled growth of abnormal white blood cells.
C) This choice is correct. Leukemia is characterized by genetic mutations in the bone marrow cells, particularly in the stem cells that produce white blood cells. These mutations lead to uncontrolled growth and proliferation of abnormal white blood cells, interfering with the normal production of other blood cells.
D) This choice is incorrect because an imbalance of red blood cells would not trigger the overproduction of white blood cells. Leukemia is specifically a disorder of white blood cell proliferation.
