A nursing student is preparing a prenatal class on the process of fetal circulation.
The nursing instructor asks the student specifically to describe the process through
the umbilical cord. Which of the following statements from the student is correct?
1. "The one artery carries freshly oxygenated blood and nutrient-rick blood back from
the placenta to the fetus."
2. "The two arteries carry freshly oxygenated blood back from the placenta to the
fetus."
3. "The two arteries in the umbilical cord carry deoxygenated blood and waste
products away from the fetus to the placenta."
4. "The two veins in the umbilical cord carry blood that is high in carbon dioxide and
other waste products away from the fetus to the placenta." - answers 3. "The two
arteries in the umbilical cord carry deoxygenated blood and waste products away
from the fetus to the placenta."
Rational: Blood pumped by the embryo's heart leaves the embryo through two
umbilical arteries. When oxygenated, the blood is returned by one umbilical vein.
A nurse is performing an assessment on a client who is at 38 weeks gestation and
notes that the FHR is 174/bpm. On the basis of this finding, the appropriate nursing
action is to:
1. Notify the physician
2. Document the findings.
3. Check the mother's heart rate
4. Tell the client that the FHR is normal. - answers 1. Notify the physican
Rational: The FHR depends on gestational age and ranges from 160-170/bpm in the
1st trimester, but slows with fetal growth to 120-160/bpm near or at term. Because
the FHR is increased from the reference range, the nurse should notify the physican.

A nurse is performing an assessment of a pregnant client who is at 28 wks gestation.
The nurse measures the fundal height in centimeters and expects he finding to be
which of the following?
1. 22 cm
2. 30 cm
3. 36 cm
4. 40 cm - answers 2. 30 cm
Rational: During the 2nd/3rd trimesters (18 wks-30wks), fundal height in cm
approximately equals the fetus' age in weeks +/- 2cm. At 16 wks, the fundus can be
located halfway between the symphysis pubis and the umbilicus. At 20-22 wks, the
fundus is at the umbilicus. At 36 wks, the fundus is at the xiphoid process.
A nurse is collecting data during an admission assessment of a client who is
