Answer to Question 1
ANS: D
This description fits that of a spherocyte. The MCV of a spherocyte is usually normal, although microspherocytes exist that have a low MCV.
Answer to Question 2
ANS: B
When anemia develops, the concentration of 2,3-biphosphoglycerate (2,3-BPG) increases. This causes a shift to the right in the oxygen dissociation curve, which results in more effective delivery of oxygen to tissue (oxygen affinity of hemoglobin decreases).
