A nurse is providing education to a client diagnosed with leukemia who asks, "What causes leukemia?" How should the nurse respond?

A) This choice is correct. Using a soft-bristled toothbrush helps prevent gum bleeding and trauma to the oral mucosa, reducing the risk of infection in clients with low platelet counts.

B) This choice is incorrect because during leukemia treatment, outdoor activities may expose the client to potential sources of infection. It is better to avoid crowded places and maintain good hand hygiene.

C) This choice is correct. Raw fruits and vegetables may carry bacteria and pathogens, and the client with leukemia, particularly those undergoing chemotherapy, is at a higher risk of infection. It is advised to thoroughly wash and cook fruits and vegetables before consumption.

D) This choice is incorrect because although emotional support from friends and family is essential, it is crucial to limit the number of visitors to reduce the risk of exposure to potential infections.

A) This choice is incorrect because leukemia is not limited to just one type. There are different subtypes of leukemia, including acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML), among others.

B) This choice is correct. Leukemia can be broadly classified into two main types: acute leukemia, which progresses rapidly and requires immediate treatment, and chronic leukemia, which progresses more slowly.

C) This choice is incorrect because the classification of leukemia is not solely based on age. Leukemia can occur in both children and adults.

D) This choice is incorrect because the classification of leukemia does not involve solid tumors. Leukemia is a cancer of the blood and bone marrow, characterized by the uncontrolled growth of abnormal white blood cells.
