Answer to Question 1

ANS: C
The histogram shows a log-normal distribution of platelet volume, with a skew to the right because of a small population of large platelets. The MPV is 8 to 10 fL.

Answer to Question 2

ANS: B
Platelet storage pool disorder is a deficiency of a-granules, also called dense bodies.
