Answer to Question 1

ANS: D
A MCHC of 53 g/dL is impossible. A red cell cannot hold this concentration of hemoglobin.

Answer to Question 2

ANS: A
When the red cell indices are calculated, they are as follows:
Mean cell volume (MCV) = (30.0/3.22)  10 = 93 fL.
Mean cell hemoglobin (MCH) = (16.0/3.22)  10 = 50 pg.
MCHC = (16.0/30.0)  100 = 53 g/dL.
