A nurse is assessing a client diagnosed with leukemia. Which finding requires immediate intervention?

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 flow cytometry analysis is not primarily used to assess the client's heart function.

B) This choice is incorrect because determining the client's blood type is not the primary purpose of flow cytometry analysis in the diagnostic evaluation of leukemia.

C) This choice is correct. Flow cytometry analysis is a specialized laboratory technique used to classify the type of leukemia and its subtype based on specific cell markers present on the surface of leukemic cells. This information helps guide the appropriate treatment plan.

D) This choice is incorrect because evaluating the client's kidney function is not the primary purpose of flow cytometry analysis in the diagnostic evaluation of leukemia.
