Final answer:
In a child with acute lymphoblastic leukemia (ALL), a nurse would expect the CBC to show leukocytosis, anemia, and thrombocytopenia due to the overproduction and malfunction of lymphocytes.
Step-by-step explanation:
When reviewing the CBC of a child with acute lymphoblastic leukemia (ALL), a nurse would typically expect to find a number of abnormalities. These may include leukocytosis, which is an excessive proliferation of white blood cells (leukocytes), particularly immature lymphocytes or blasts.
There could also be evidence of anemia due to impaired production of red blood cells (erythrocytes), and thrombocytopenia, which is a low platelet count.
Since the marrow is overcrowded with abnormal leukocytes, the production of normal blood cells is often disrupted. The involvement of lymphoid stem cells in ALL means that the lymphocytes produced are not functioning as they should and are not effective as part of the immune system.
