A nurse is conducting a health history assessment for a client newly diagnosed with leukemia. Which risk factor should the nurse prioritize when asking about the client's medical history?

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.

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.
