A nurse is reviewing the medical records of clients diagnosed with leukemia on a cancer unit. Which client's medical history should the nurse recognize as a possible risk factor for developing leukemia?
A 25-year-old client with a sedentary lifestyle
A 40-year-old client with a vegetarian diet
A 60-year-old client with a history of tobacco use
A 70-year-old client with a family history of diabetes
The Correct Answer is C
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 C
Explanation
A) This choice is incorrect because CLL specifically involves the overproduction of abnormal lymphocytes, not myeloid cells. Myeloid cells are affected in other types of leukemia, such as AML.
B) This choice is incorrect because CLL is a chronic and indolent type of leukemia. It has a slow onset and progresses slowly over time, unlike some other leukemias that may have a more rapid course.
C) This choice is correct. In CLL, abnormal lymphocytes, mainly B-lymphocytes, accumulate in the bone marrow and interfere with the production of other blood cells, including red blood cells, platelets, and other white blood cells.
D) This choice is incorrect because CLL does not involve a genetic mutation leading to uncontrolled growth of red blood cells. That description is more characteristic of polycythemia vera, a different type of blood disorder.
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.
