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

A) This choice is incorrect because a stem cell transplant is primarily used to replace the damaged bone marrow and restore normal blood cell production, but it is not a specific treatment for anemia.

B) This choice is correct. A blood transfusion involves infusing healthy red blood cells into the client's bloodstream to address anemia and improve oxygen-carrying capacity.

C) This choice is incorrect because radiation therapy is primarily used to target and destroy cancer cells, not to address anemia.

D) This choice is incorrect because immune checkpoint inhibitors are a type of immunotherapy used to enhance the body's immune response against cancer cells, but they are not a specific treatment for anemia.

A) This choice is incorrect because leukemia does not lead to the increased production of normal red blood cells. Instead, it causes the overproduction of abnormal white blood cells.

B) This choice is incorrect because leukemia does not lead to the accumulation of normal platelets in the blood. Thrombocytopenia, or low platelet count, is common in leukemia due to the suppression of normal platelet production in the bone marrow.

C) This choice is correct. In leukemia, the proliferation of abnormal white blood cells crowds out and suppresses the normal bone marrow stem cells responsible for producing red blood cells, platelets, and other white blood cells. This suppression leads to anemia and thrombocytopenia.

D) This choice is incorrect because while cancerous cells may infiltrate healthy tissues in other types of cancer, leukemia primarily affects the bone marrow and blood, not other organs or tissues.
