Answer to Question 1

ANS: B
Incubating the blood at 37 C for 24 hours can increase the sensitivity of the osmotic fragility so that a previously normal result becomes abnormal. During this incubation period, red cells become metabolically deprived and tend to lose membrane surface because of their relative membrane instability.

Answer to Question 2

ANS: C
After some viral infections, particularly with parvovirus B19 that invades developing red cells and inhibits their growth, a severe drop in hemoglobin can occur. This is termed an aplastic crisis.
