A client newly diagnosed with acute lymphocytic leukemia (ALL) asks the nurse, "What happens to the normal bone marrow cells in ALL?" How should the nurse respond?
"In ALL, the bone marrow produces an excess of abnormal red blood cells, leading to anemia."
"ALL results in the overproduction of normal white blood cells, leading to an increased immune response."
"The abnormal lymphocytes in ALL crowd out the normal bone marrow cells, leading to decreased production of other blood cells."
"In ALL, the bone marrow becomes fibrous and unable to produce any blood cells."
The Correct Answer is C
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 C
Explanation
A) This choice is incorrect because a sedentary lifestyle is not a known risk factor for leukemia. Physical inactivity is associated with other health conditions but not leukemia.
B) This choice is incorrect because having a vegetarian diet is not a risk factor for developing leukemia.
C) This choice is correct. A history of tobacco use is a potential risk factor for leukemia. Smoking is associated with an increased risk of various cancers, and while the link to leukemia is not as clear as with other cancers, it is still considered a possible risk factor.
D) This choice is incorrect because a family history of diabetes is not a known risk factor for leukemia.
Correct Answer is B
Explanation
A) This choice is incorrect because a complete blood count (CBC) provides information about the number of blood cells, but it does not directly assess the bone marrow for leukemia.
B) This choice is correct. Bone marrow aspiration and biopsy involve the collection of bone marrow samples from the sternum or hip bone. These samples are then analyzed to determine the presence of leukemia cells, assess cell morphology, and determine the type of leukemia.
C) This choice is incorrect because flow cytometry analysis is used to identify specific markers on the surface of cells and can aid in diagnosing and classifying leukemia. However, it is not the primary test used to assess the bone marrow directly.
D) This choice is incorrect because magnetic resonance imaging (MRI) is not commonly used to assess bone marrow in the diagnostic evaluation of leukemia.
