Answer to Question 1

ANS: A
The best use for bone marrow aspirate smear is for counting the differential. The biopsy is better for determining overall cellularity, estimating the fat-to-cell ratio, and evaluating for the possible presence of focal lesions.

Answer to Question 2

ANS: B
Most bone marrow aspirates are obtained from the posterior iliac crest in an adult. The anterior iliac crest can also be used and occasionally the ribs or vertebrae. The sternum is rich in marrow and a good specimen can be obtained from it, but it is not recommended because of the risk of puncture to the underlying heart and great vessels.
