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?

A) This choice is incorrect because mild fatigue and weakness are common symptoms in leukemia and may be expected in the client's condition.

B) This choice is correct. Bruising and petechiae are signs of decreased platelet count and potential clotting abnormalities, which can lead to bleeding complications. Immediate intervention is necessary to prevent serious bleeding.

C) This choice is incorrect because a weight loss of 2 pounds in a month is not alarming and can be caused by various factors unrelated to leukemia.

D) This choice is incorrect because occasional headaches and dizziness are not immediate concerns in leukemia and may have other causes.

A) This choice is incorrect because the lymphatic system does not filter and remove abnormal blood cells in leukemia. The role of the lymphatic system is primarily related to the circulation of lymph fluid and the immune response, not the removal of abnormal blood cells.

B) This choice is incorrect because the lymphatic system is not responsible for producing and releasing abnormal white blood cells in leukemia. Leukemia originates from the bone marrow, not the lymphatic system.

C) This choice is correct. Leukemia is primarily a disorder of the bone marrow and blood. It does not directly involve the lymphatic system, which is responsible for carrying lymph fluid and supporting the body's immune function.

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