A client with leukemia is experiencing severe mucositis as a side effect of chemotherapy. Which nursing intervention should be prioritized to manage mucositis?

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.

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.
