A nurse in labor and delivery is caring for a client. Following the delivery of the placenta, the nurse examines the umbilical cord.
Which of the following vessels should the nurse expect to observe in the umbilical cord?
One artery and one vein.
Two veins and one artery.
Two arteries and two veins.
Two arteries and one vein.
The Correct Answer is D
Choice A rationale
The umbilical cord typically contains two arteries and one vein, not one artery and one vein. The umbilical arteries carry deoxygenated blood from the fetus to the placenta, while the umbilical vein carries oxygenated blood from the placenta to the fetus.
Choice B rationale
The umbilical cord typically contains two arteries and one vein, not two veins and one artery. The umbilical arteries carry deoxygenated blood from the fetus to the placenta, while the umbilical vein carries oxygenated blood from the placenta to the fetus.
Choice C rationale
The umbilical cord typically contains two arteries and one vein, not two arteries and two veins. The umbilical arteries carry deoxygenated blood from the fetus to the placenta, while the umbilical vein carries oxygenated blood from the placenta to the fetus.
Choice D rationale
The umbilical cord typically contains two arteries and one vein. The umbilical arteries carry deoxygenated blood from the fetus to the placenta, while the umbilical vein carries oxygenated blood from the placenta to the fetus.

Correct Answer is A
Explanation
Choice A rationale
Late decelerations in the Fetal Heart Rate (FHR) are a type of FHR pattern observed during labor, indicating a potential compromise of fetal well-being. They often begin just after a contraction, with their lowest point occurring after the peak of the contraction. These decelerations are associated with maternal and fetal conditions. Changing the client’s position can help alleviate the pressure on the fetus and improve blood flow, potentially reducing the occurrence of late decelerations. Therefore, the first action the nurse should take when noting late decelerations in the FHR is to change the client’s position.
Choice B rationale
Applying a fetal scalp electrode is a method used to monitor the FHR more accurately. However, it is not the first action to take when late decelerations are noted. The priority is to address the potential cause of the decelerations, such as changing the client’s position to improve blood flow.
Choice C rationale
Administering oxygen can help increase the oxygen supply to the fetus. However, it is not the first action to take when late decelerations are noted. The priority is to address the potential cause of the decelerations, such as changing the client’s position to improve blood flow.
Choice D rationale
Increasing the rate of the IV infusion can help improve uteroplacental perfusion. However, it is not the first action to take when late decelerations are noted. The priority is to address the potential cause of the decelerations, such as changing the client’s position to improve blood flow.
Correct Answer is D
Explanation
If a patient in labor who has received an epidural anesthesia block has a blood pressure reading of 80/40 mm Hg, the nurse’s immediate course of action should be to position the patient laterally. This helps to maximize venous return and cardiac output, thereby improving maternal blood pressure and fetal perfusion.
