Answer to Question 1

ANS: B
In patients taking iron supplements, occult blood in stools may be obscured by the black colora-tion of iron in stool. Guaiac test results may occasionally be false-positive.

Answer to Question 2

ANS: C
Before starting therapy, evaluate the patient's iron status, because the efficacy of epoetin alfa is decreased if iron stores are insufficient to promote erythropoiesis.
