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 D
Explanation
A) This choice is incorrect because while a complete blood count (CBC) is an important initial screening test for leukemia, it alone is not definitive for diagnosis. A CBC may show abnormal levels of blood cells, prompting further investigation, including a bone marrow biopsy.
B) This choice is incorrect because a urinalysis is not used to diagnose leukemia. It is a test used to evaluate kidney function and detect urinary abnormalities.
C) This choice is incorrect because a chest X-ray is not a definitive diagnostic tool for leukemia. It is primarily used to assess the lungs and chest organs for conditions such as pneumonia or tumors.
D) This choice is correct. A bone marrow biopsy is a definitive diagnostic tool to confirm leukemia. In this procedure, a small sample of bone marrow is taken from the hipbone or breastbone and examined under a microscope to determine if leukemia cells are present. It allows for the identification of abnormal cells in the bone marrow, helping to establish the diagnosis and type of leukemia.
Correct Answer is B
Explanation
A) This choice is incorrect because fatigue and weakness are common symptoms in leukemia, but they are not specific enough to confirm the diagnosis on their own.
B) This choice is correct. Night sweats and fever are classic symptoms of leukemia, especially in cases of acute leukemia. These symptoms are related to the presence of abnormal white blood cells in the bloodstream and their impact on the body's immune response.
C) This choice is incorrect because unexplained weight gain is not a typical symptom of leukemia. Weight loss is more commonly associated with this condition due to decreased appetite and increased energy expenditure.
D) This choice is incorrect because persistent headaches are not specific to leukemia and may indicate other underlying health issues.
