Answer to Question 1

B
Feedback:
Sickle cell anemia is a chronic hemolytic anemia that occurs most commonly in people of African descent, so it would be appropriate to have genetic screening to determine the risk associated with having children. The other answers are incorrect because they are not associated with people of African descent.

Answer to Question 2

C
Feedback:
Antiemetics act by depressing the hyperactive vomiting reflex, either locally or through alteration of CNS actions. Options A, B, and D are not the main action of antiemetics.
