2.In fetal circulation, most blood will bypass the fetal lungs via the:
a. inferior vena cava c. foramen ovale
b. ductus venosus d. ductus arteriosus
ANS: C
Feedback
A Incorrect. In fetal circulation, most blood will not bypass the fetal lungs via the inferior vena cava, instead most of the blood from the placenta enters the inferior vena cava on the way directly to the heart, thus bypassing the lungs.
B Incorrect. In fetal circulation, most blood will not bypass the fetal lungs via the ductus venosus; 60% of the blood from the placenta passes through the ductus venosus directly into the inferior vena cava.
C Correct. In fetal circulation, most blood will bypass the fetal lungs via the foramen ovale, an opening between the right and left atria of the fetal heart.
D Incorrect. In fetal circulation, most blood will not bypass the fetal lungs via the ductus arteriosus, however, a large amount of blood from the placenta travels through the ductus arteriosus (channel between the main pulmonary artery and the aorta).

OBJ: Cognitive Level: Knowledge
3.When the fetus makes the transition to becoming a newborn and extrauterine life begins, there occurs a series of changes, including decreased pulmonary vascular resistance, increased pulmonary blood flow, increased pressure of the left atrium, decreased pressure of the right atrium, and closure of which of the following structures?
a. foramen ovale c. inferior vena cava
b. ductus venosus d. superior vena cava
ANS: 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.
