Answer to Question 1

ANS: D
In the United States, African American male subjects are the ethnic group that most commonly has G6PD A- deficiency. From 10 to 11 of these subjects carry this gene. The gene is X linked, so that female subjects are carriers and generally do not have clinical problems.

Answer to Question 2

ANS: C
After splenectomy, the anemia is usually corrected and reticulocyte counts return to high normal. However, the consequences of splenectomy, done for whatever reason, are the appearance of Howell-Jolly bodies, siderocytes, and target cells in red cells. Spherocytes will still be observable in hereditary spherocytosis.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
