ANS:  D

 

	Feedback

B	Incorrect. The neonatal or newborn period of life is not defined as the first 48 hours.

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).

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.

4. After a long labor, the mother is concerned about the swelling of her baby’s scalp. The newborn is 24 hours old. The nurse palpates the scalp and finds swelling that extends across the suture lines. In addition to explaining the probable cause of the swelling and the time of resolution, the nurse explains that the term for this condition is:

a.	cephalhematoma	c.	molding
b.	caput succedaneum	d.	crepitation

 

 

ANS:  B

 

	Feedback
A	Incorrect. Cephalhematoma will usually develop after 24 hours, indicates rupture of blood vessels and bleeding, but does not extend across the suture lines.
B	Correct. Caput succedaneum is often evident after long labor, is swelling of the soft tissues of the scalp. The edema extends across the suture lines, and presents within the first 24 hours following birth.
C	Incorrect. Molding describes the misshapen appearance of the head following live birth.
D	Incorrect. Crepitation is the noisy discharge of gas from the intestine through the anus.

5. The umbilical cord, which connects the fetus to the placenta, contains:

b.	two veins and two arteries	d.	two arteries and one vein

 

 

ANS:  D

 

	Feedback
A	Incorrect. The umbilical cord, which connects the fetus to the placenta, does not contain one vein and one artery.
B	Incorrect. The umbilical cord, which connects the fetus to the placenta, does not contain two veins and two arteries.
C	Incorrect. The umbilical cord, which connects the fetus to the placenta, does not contain one artery and two veins.
D	Correct. The umbilical cord, which connects the fetus to the placenta, does contains two arteries and one vein.
