The patient with acute myelogenous leukemia (AML) asks why he is making more WBCs when he already has so many. Which statement clarifies the underlying pathophysiology related to the patient's white blood cells (WBCs)?
a. "The large number of leukemic white cells that you already have are not as effective as normal white cells."
b. "The large number of leukemic white cells that you already have protect against infection."
c. "The large number of leukemic white cells that you already have attempt to take over the functions of RBCs.
d. "The large number of leukemic white cells that you already have are produced by the lymphatic system."
A
The many leukemic white cells cannot function as normal WBCs do. The bone marrow "rushes" production of immature white cells (blasts) to try to create adequate protection. These cells do not protect against infection, nor do they take over the functions of the RBCs. AML originates in the bone marrow.
