Answer to Question 1

ANS: B
The opening in the septal wall allows for blood to flow from the higher pressure left ventricle into the lower pressure right ventricle. This left-to-right shunt creates increased pulmonary blood flow. The shunt is one way, from high pressure to lower pressure; oxygenated and unoxygenated blood do not mix. The outflow of blood from the ventricles is not affected by the septal defect.

Answer to Question 2

ANS: C
At 8 to 12 weeks of age, the infant turns the head to the side when sound is made at the level of the ear. At 16 to 24 weeks, the infant locates sound by turning the head to the side and then looking up or down. At 24 to 32 weeks, infants respond to their own name. At 32 to 40 weeks, the infant localizes sounds by turning the head directly toward the sound.
