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 incorrect because swollen lymph nodes are more characteristic of chronic leukemia, not acute leukemia like AML.

B) This choice is correct. Chronic lymphocytic leukemia (CLL) is commonly associated with enlarged lymph nodes due to the accumulation of abnormal lymphocytes in these areas. It is a slow-progressing leukemia and often presents with lymphadenopathy.

C) This choice is incorrect because while ALL may involve enlarged lymph nodes, it is more commonly associated with symptoms like fatigue, bleeding, and bone pain.

D) This choice is incorrect because while CML may present with enlarged spleen and liver, it is less likely to cause significant lymphadenopathy compared to CLL.

A) This choice is incorrect because increased platelet production would not lead to easy bruising and petechiae. It would, in fact, improve clotting abilities.

B) This choice is incorrect because overproduction of red blood cells would not directly cause easy bruising and petechiae. It may lead to symptoms like fatigue and pallor.

C) This choice is correct. Easy bruising and petechiae are common in leukemia due to a deficiency of platelets and impaired clotting factors in the blood. Leukemia can lead to decreased platelet production and clotting abnormalities, resulting in easy bleeding and bruising.

D) This choice is incorrect because a deficiency of white blood cells would not directly cause easy bruising and petechiae. It might lead to an increased risk of infections.
