Answer to Question 1

A

Feedback
A Correct. The transition to extrauterine life requires the lungs to initiate respirations and the PaO2 levels increase. The opening between the left and right atria, the foramen ovale, closes shortly after birth.
B Incorrect. The ductus venosus closes more gradually, usually within 2 weeks of birth.
C Incorrect. The inferior vena cava must remain open for life to persist.
D Incorrect. The superior vena cava must remain open for life to persist.

Answer to Question 2

B
The nurse will greet the child at eye level. Towering over the child is frightening. The nurse should be warm and friendly. The nurse should be calm and unhurried when talking with the child and family.
