Answer 1 is correct because leukemia causes a decrease in white blood cells (WBCs). Answer 2 is incorrect because the nurse should not expect abnormal BUN in a child with a new diagnosis of leukemia since the disease affects bone marrow function, not kidney function. Answer 3 is correct because leukemia causes a decrease in red blood cells (RBCs). Answer 4 is correct because leukemia causes a decrease in platelets (PLTs). Answer 5 is incorrect because the nurse should not expect abnormal sodium in a child with a new diagnosis of leukemia. Sodium is a good indicator of fluid status and not indicative of bone marrow functioning. Answer 6 is correct because leukemia causes a decrease in hemoglobin.
