A) High blast cell counts and fever

B) Decreased oxygen partial pressure and weight loss

C) Increased serum potassium and sodium levels

D) Increased blood urea nitrogen (BUN) and bone pain

11. A 70-year-old woman has received a diagnosis of chronic myelogenous leukemia (CML) after a clinical investigation sparked by the presence of leukocytosis in her routine blood work. What clinical course should her care provider tell her to expect?

A) "You can expect your blood results, fatigue, and susceptibility to infection to gradually worsen over a few years."

B) "You could remain in the chronic stage of CML for several years before it accelerates and culminates in a crisis."

C) "It's likely that this will give you chronic fatigue and malaise for the rest of your life, but that will probably be the extent of your symptoms."
