Answer to Question 1

ANS: C
Poikilocytosis refers to a variation in the shape of red cells. Anisocytosis refers to variation in size; when this is present, the RDW should be increased and the patient is most likely anemic.

Answer to Question 2

ANS: C
Spherocytes can slightly elevate the MCHC because they have lost some membrane in the process of sphering and so the hemoglobin concentration tends to increase slightly. The MCV is usually not significantly affected (although microspherocytes exist). Spherocytes decrease the ESR and have no effect on the white count.
