Answer to Question 1

ANS: B
Megakaryocytes are the largest cell in the bone marrow, and they are easily seen and counted under 10.

Answer to Question 2

ANS: A
Coverslip smears from a bone marrow spicule are the preferred type of preparation for bone marrow aspirates. The advantage to them over slides is that less trauma occurs to the cells because they weigh so much less (relatively speaking). If done correctly, then a good monolayer of cells in the marrow can be stained and then evaluated.
