Answer to Question 1

ANS: C
Infants with tetralogy of Fallot experience cyanosis after crying or during feeding. Infants with AVC defect may experience cyanosis, but it is not related to feeding or crying. Infants do not experience cyanosis with either VSD or ASD.

Answer to Question 2

ANS: B
In transposition of the great arteries, the pulmonary artery leaves the left ventricle and the aorta exits from the right ventricle. The pulmonary artery normally leaves the right ventricle. Neither VSD nor ASD is associated with transposition of the great arteries.
