C. "The normal fetal heartbeat range is 160 to 180 beats per minute
in pregnancy."
D. "Two arteries carry deoxygenated blood and waste products
away from the fetus to the placenta."

blood is transported to the fetus by one umbilical vein. The normal
fetal heartbeat range is considered to be 110 to 160 beats per
minute. Two arteries carry deoxygenated blood and waste products
from the fetus, and one umbilical vein carries oxygenated blood
and provides oxygen and nutrients to the fetus. Blood pumped by
the embryo's heart leaves the embryo through two umbilical
arteries.
The nursing instructor teaches a group of students about fetal
circulation and then asks a student to describe fetal circulation,
specically the ductus venosus. Which statement by the student
indicates an understanding of the ductus venosus?
A. "It connects the pulmonary artery to the aorta."
B. "It is an opening between the right and left atria."
C. "It connects the umbilical vein to the inferior vena cava."
D. "It connects the umbilical artery to the inferior vena cava." -
correct answer ✅C. "It connects the umbilical vein to the inferior
vena cava."
The ductus venosus connects the umbilical vein to the inferior vena
cava. The foramen ovale is a temporary opening between the right

and left atria. The ductus arteriosus joins the aorta and the
pulmonary artery.
A pregnant client tells the clinic nurse that they want to know the
sex of the baby as soon as it can be determined. The nurse plans to
inform the client that they will be able to find out the sex at 16
weeks' gestation because of which factor?
A. The appearance of the fetal external genitalia.
B. The beginning of differentiation in the fetal groin.
C. The fetal testes are descended into the scrotal sac.
D. The internal differences in different genders become apparent. -
correct answer ✅A. The appearance of the fetal external genitalia.
Between weeks 16 and 20, the external genitalia of the fetus have
developed to such a degree that the sex of the fetus can be
determined visually. Differentiation of the external genitalia occurs
at the end of the ninth week. Testes begin to descend into the
scrotal sac at the end of the 38th week. Internal differences in the
genders occur at the end of the seventh week.

Practice Exam Questions And
Answers
The nurse is performing an assessment on a client who is at 38
weeks' gestation and notes that the fetal heart rate (FHR) is 174
beats per minute. On the basis of this finding, what is the priority
nursing action?
A. Document the finding.
B. Notify the obstetrician (OB).
C. Check the mother's heart rate.
D. Tell the client that the fetal heart rate is normal. -
correct answer ✅B. Notify the obstetrician (OB).
The FHR depends on gestational age and ranges from 160 to 170
beats per minute in the first trimester but slows with fetal growth
to 110 to 160 beats per minute. If the FHR is less than 110 beats per
minute or more than 160 beats per minute with the uterus at rest,
the fetus may be in distress. Because the FHR is increased from the
reference range, the nurse would notify the OB. Options 3 and 4 are
inappropriate actions based on the information in the question.
Although the nurse documents the findings, based on the
information in the question, the OB needs to be notified.
