A client with leukemia is undergoing a bone marrow biopsy for diagnosis and staging. The nurse should explain that the primary purpose of this procedure is to:

A) This choice is incorrect because swollen lymph nodes are more characteristic of chronic leukemia, not acute leukemia like AML.

B) This choice is correct. Chronic lymphocytic leukemia (CLL) is commonly associated with enlarged lymph nodes due to the accumulation of abnormal lymphocytes in these areas. It is a slow-progressing leukemia and often presents with lymphadenopathy.

C) This choice is incorrect because while ALL may involve enlarged lymph nodes, it is more commonly associated with symptoms like fatigue, bleeding, and bone pain.

D) This choice is incorrect because while CML may present with enlarged spleen and liver, it is less likely to cause significant lymphadenopathy compared to CLL.

A) This choice is incorrect because while aerobic exercise is beneficial for overall health, it may not directly protect the client from infection in the context of low WBC count during chemotherapy.

B) This choice is incorrect because during chemotherapy, live vaccines should be avoided as they can pose a risk to immunocompromised clients with low WBC counts.

C) This choice is correct. Placing the client in a private room with negative pressure helps reduce the risk of exposure to infectious agents, especially in immunocompromised clients with low WBC counts who are at higher risk of infection.

D) This choice is incorrect because limiting the number of healthcare providers entering the client's room may be beneficial to reduce the risk of exposure to potential infections, but placing the client in a private room with negative pressure is a more comprehensive measure.
