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 B
Explanation
Choice A rationale
A baseline BP of 140/85 mmHg is considered high, but a current BP of 129/80 mmHg is within the normal range. Therefore, this would not typically indicate a risk for pregnancy-induced hypertension.
Choice B rationale
A significant increase in blood pressure from a baseline of 110/70 mmHg to a current BP of 145/85 mmHg could indicate a risk for pregnancy-induced hypertension.
Choice C rationale
A slight increase in blood pressure from a baseline of 120/80 mmHg to a current BP of 126/85 mmHg would not typically indicate a risk for pregnancy-induced hypertension.
Choice D rationale
An increase in blood pressure from a baseline of 110/60 mmHg to a current BP of 120/63 mmHg would not typically indicate a risk for pregnancy-induced hypertension.
Correct Answer is B
Explanation
Choice A rationale
Vaginal discharge is common during pregnancy due to the increased production of estrogen and greater blood flow to the pelvic area. It is not typically a sign of preeclampsia.
Choice B rationale
Elevated blood pressure is a primary symptom of preeclampsia. If a pregnant client has high blood pressure, it should indicate to the nurse that the client requires further evaluation for this disorder.
Choice C rationale
Joint pain is not typically a symptom of preeclampsia. It could be related to other conditions or simply a result of the physical changes of pregnancy.
Choice D rationale
Increased urine output is not typically associated with preeclampsia. In fact, decreased urine output could potentially be a sign of kidney problems related to preeclampsia.
