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 C
Explanation
Choice A reason:
Fetal head compression is associated with early decelerations, not late. Early decelerations are a normal finding during labor as the fetal head is compressed during contractions, leading to a vagal response that temporarily decreases the heart rate.
Choice B reason:
Umbilical cord compression leads to variable decelerations, not late. Variable decelerations can occur at any time during the contraction cycle and are caused by compression of the umbilical cord, which can restrict blood flow to the fetus.
The correct answer is C. Uteroplacental insufficiency.
Late decelerations are indicative of uteroplacental insufficiency, which is a condition where the placenta is not delivering enough oxygen and nutrients to the fetus.
Choice D reason:
Maternal bradycardia, which is a slower than normal heart rate in the mother, does not cause late decelerations in the fetus. Instead, maternal bradycardia can be a separate concern and does not directly affect the fetal heart rate pattern observed on the monitor.
Correct Answer is C
Explanation
Choice A rationale
Implementing seizure precautions is not necessary based on these lab results. Seizure precautions are typically implemented for patients with a known seizure disorder or those who are at risk for seizures, such as patients with severe preeclampsia or eclampsia, neither of which can be diagnosed based on these lab results.
Choice B rationale
Checking deep tendon reflexes every hour is not indicated based on these lab results. This action is typically taken for patients with altered neurological status or those receiving certain medications that can affect muscle tone.
Choice C rationale
Reviewing the daily logs of the patient is a good practice in general to monitor the patient’s progress and response to treatment. However, it is not a specific action that should be taken based on these lab results.
Choice D rationale
Obtaining a prescription for methyldopa is not indicated based on these lab results.
Methyldopa is a medication used to treat high blood pressure, and there is no indication from these lab results that the patient has high blood pressure.
