A client is diagnosed with acute leukemia. The nurse explains that acute leukemia is characterized by:

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.

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.
