Answer to Question 1

ANS: B
Coverslip smears are used primarily for bone marrow aspirates. They are too fragile to routinely handle when making smears of blood films; they also must be manually stained, which is not practical to do in most laboratories.

Answer to Question 2

ANS: C
Increased lipids in the plasma can cause the appearance of holes all over the blood film. Some of the other hematology parameters should be carefully evaluated as they may also be influenced by the presence of these lipids (e.g., hemoglobin).
