Answer to Question 1

ANS: A
Anisocytosis is a significant variation in the size of red cells; it does not indicate what those variations are (e.g., normocytic and microcytic, normocytic and macrocytic). The red blood cell distribution width (RDW) should be increased to correlate with this finding.

Answer to Question 2

ANS: C
When too many monocytes are found at the sides and/or in the featheredge of the slide, distribution of white cells on the slide is poor. A new slide must be made and stained.
