A nurse is reviewing the diagnostic tests of a client suspected of having leukemia. The laboratory report shows elevated levels of blast cells in the peripheral blood. Which test result supports the suspicion of leukemia?
Elevated red blood cell count
Elevated white blood cell count
Elevated platelet count
Elevated levels of blast cells in the bone marrow
The Correct Answer is B
A) This choice is incorrect because an elevated red blood cell count is not a typical finding in leukemia. Leukemia is characterized by the overproduction of white blood cells, not red blood cells.
B) This choice is correct. Leukemia is associated with an elevated white blood cell count, particularly an abnormal increase in blast cells, which are immature cells indicative of leukemia.
C) This choice is incorrect because an elevated platelet count is not a typical finding in leukemia. Leukemia is more commonly associated with thrombocytopenia, which is a decreased platelet count.
D) This choice is incorrect because the laboratory report indicating elevated levels of blast cells in the peripheral blood supports the suspicion of leukemia, not the blast cells' presence in the bone marrow.

Correct Answer is B
Explanation
A) This choice is incorrect because assessing bone density and strength is not the primary purpose of a CT scan in the diagnostic evaluation of leukemia.
B) This choice is correct. A CT scan is commonly used to identify enlarged lymph nodes and organs, which can occur in leukemia as a result of cancerous cell proliferation and infiltration into the lymphatic system and other organs.
C) This choice is incorrect because measuring lung capacity is not the primary purpose of a CT scan in the diagnostic evaluation of leukemia.
D) This choice is incorrect because monitoring cardiac function is not the primary goal of a CT scan in the diagnostic evaluation of leukemia.
Correct Answer is D
Explanation
A) This choice is incorrect because a family history of diabetes is not a known risk factor for leukemia. While genetics can play a role in some leukemia cases, diabetes is not associated with leukemia development.
B) This choice is incorrect because exposure to asbestos is a risk factor for certain types of cancer, such as lung cancer and mesothelioma, but it is not a primary risk factor for leukemia.
C) This choice is incorrect because while autoimmune disorders can affect the immune system, they are not a known risk factor for leukemia.
D) This choice is correct. A previous diagnosis of lymphoma is a significant risk factor for developing leukemia. Lymphoma and leukemia are both types of blood cancers, and individuals with a history of lymphoma have an increased risk of developing leukemia.
