A nurse is providing education to a client recently diagnosed with chronic lymphocytic leukemia (CLL). The client asks, "How does CLL differ from other types of leukemia?" How should the nurse respond?
"CLL involves the overproduction of abnormal myeloid cells, while other types of leukemia affect lymphocytes."
"Unlike other leukemias, CLL has a rapid onset and aggressive course of disease progression."
"In CLL, abnormal lymphocytes accumulate and interfere with the production of other blood cells in the bone marrow."
"CLL is characterized by a genetic mutation in the bone marrow that leads to uncontrolled growth of red blood cells."
The Correct Answer is C
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 D
Explanation
A) This choice is incorrect because while a complete blood count (CBC) is an important initial screening test for leukemia, it alone is not definitive for diagnosis. A CBC may show abnormal levels of blood cells, prompting further investigation, including a bone marrow biopsy.
B) This choice is incorrect because a urinalysis is not used to diagnose leukemia. It is a test used to evaluate kidney function and detect urinary abnormalities.
C) This choice is incorrect because a chest X-ray is not a definitive diagnostic tool for leukemia. It is primarily used to assess the lungs and chest organs for conditions such as pneumonia or tumors.
D) This choice is correct. A bone marrow biopsy is a definitive diagnostic tool to confirm leukemia. In this procedure, a small sample of bone marrow is taken from the hipbone or breastbone and examined under a microscope to determine if leukemia cells are present. It allows for the identification of abnormal cells in the bone marrow, helping to establish the diagnosis and type of leukemia.
Correct Answer is C
Explanation
A) This choice is incorrect because replacing damaged bone marrow with healthy stem cells is the primary goal of a stem cell transplant, not radiation therapy.
B) This choice is incorrect because while radiation therapy may be used to reduce the size of leukemia masses and induce remission in some cases, it is not typically used to eliminate all leukemia cells throughout the body.
C) This choice is correct. Radiation therapy is used to target and destroy cancer cells in specific areas where leukemia is localized, such as in the brain or other parts of the body. It can be used in combination with other treatment modalities.
D) This choice is incorrect because enhancing the body's immune response against leukemia is the goal of immunotherapy, not radiation therapy.
