A client asks the nurse about the role of the lymphatic system in leukemia. How should the nurse respond?
"In leukemia, the lymphatic system helps filter and remove abnormal blood cells from the circulation."
"The lymphatic system is responsible for producing and releasing abnormal white blood cells in leukemia."
"Leukemia does not involve the lymphatic system; it only affects the bone marrow and blood."
"The lymphatic system transports cancerous cells from the bone marrow to other organs and tissues."
The Correct Answer is C
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.

Correct Answer is C
Explanation
A) This choice is incorrect because ALL does not result in the overproduction of red blood cells. It primarily affects lymphocytes, not red blood cells.
B) This choice is incorrect because ALL involves the overproduction of abnormal lymphocytes, not normal white blood cells. These abnormal lymphocytes crowd out normal cells.
C) This choice is correct. In ALL, the uncontrolled proliferation of abnormal lymphocytes leads to the overcrowding of the bone marrow. As a result, normal bone marrow cells, including red blood cells, platelets, and other white blood cells, are suppressed, leading to various cytopenias.
D) This choice is incorrect because ALL does not cause the bone marrow to become fibrous and unable to produce any blood cells. That description is more characteristic of myelofibrosis, a different bone marrow disorder.
Correct Answer is D
Explanation
A) This choice is incorrect because a bone marrow biopsy is not performed to remove a tumor mass. The purpose of the procedure is to obtain a sample of bone marrow tissue for diagnostic evaluation.
B) This choice is incorrect because assessing the presence of circulating cancer cells in the bloodstream is typically done through a blood test, not a bone marrow biopsy. The biopsy provides direct information about the condition of the bone marrow.
C) This choice is incorrect because evaluating the overall blood cell count and differential is typically done through a complete blood count (CBC) test, not a bone marrow biopsy. The biopsy provides more detailed information about the bone marrow and its cellular composition.
D) This choice is correct. The primary purpose of a bone marrow biopsy is to obtain a sample of bone marrow tissue for examination under a microscope. This allows healthcare professionals to assess the presence of abnormal cells, determine the type and extent of leukemia, and guide treatment decisions.
