  a. Atrioventricular canal (AVC) defect
  b. Ventricular septal defect (VSD)
  c. Tetralogy of Fallot
  d. Atrial septal defect (ASD)

Question 2

A newborn is severely cyanotic. An echocardiogram reveals transposition of the great arteries. What is the characteristic defect associated with this condition?
 
  a. The pulmonary artery leaving the right ventricle
  b. The aorta leaving the right ventricle
  c. Ventricular septal defect (VSD)
  d. Atrial septal defect (ASD)

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.
