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

Answer and Explanation

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 B

Explanation

A) This choice is incorrect because a complete blood count (CBC) provides information about the number of blood cells, but it does not directly assess the bone marrow for leukemia.

B) This choice is correct. Bone marrow aspiration and biopsy involve the collection of bone marrow samples from the sternum or hip bone. These samples are then analyzed to determine the presence of leukemia cells, assess cell morphology, and determine the type of leukemia.

C) This choice is incorrect because flow cytometry analysis is used to identify specific markers on the surface of cells and can aid in diagnosing and classifying leukemia. However, it is not the primary test used to assess the bone marrow directly.

D) This choice is incorrect because magnetic resonance imaging (MRI) is not commonly used to assess bone marrow in the diagnostic evaluation of leukemia.

A. Targeted therapy uses medications derived from natural sources, while chemotherapy uses synthetic drugs. B. Targeted therapy specifically targets leukemia cells, while chemotherapy affects both cancerous and healthy cells. C. Targeted therapy requires hospitalization, while chemotherapy is administered on an outpatient basis. D. Targeted therapy is a first-line treatment for leukemia, while chemotherapy is reserved for advanced stages.

Correct Answer is B

Explanation

A) This choice is incorrect because the distinction between targeted therapy and chemotherapy is not based on whether the medications are derived from natural or synthetic sources.

B) This choice is correct. Targeted therapy is designed to selectively target leukemia cells, minimizing damage to healthy cells and reducing side effects compared to traditional chemotherapy, which affects both cancerous and healthy cells.

C) This choice is incorrect because the method of administration (hospitalization or outpatient) can vary for both targeted therapy and chemotherapy, depending on the specific drug and treatment plan.

D) This choice is incorrect because targeted therapy and chemotherapy are used in various stages of leukemia treatment, depending on the type and stage of the disease.
