A nurse in labor and delivery is caring for a client. Following 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?
Two arteries and one vein
Two veins and one artery
One artery and one vein
Two arteries and two veins
The Correct Answer is A
The correct answer is A. Two arteries and one vein.
A. Two arteries and one vein is the typical composition of the umbilical cord vessels. The umbilical arteries carry deoxygenated blood and waste products away from the fetus, while the umbilical vein carries oxygenated blood and nutrients to the fetus.
B. Two veins and one artery is not the usual configuration of the umbilical cord vessels. The presence of two veins is atypical.
C. One artery and one vein is an abnormal finding and may be associated with certain congenital anomalies or fetal abnormalities. This configuration is not the norm.
D. Two arteries and two veins is not a standard or physiological composition of the umbilical cord. The typical configuration is two arteries and one vein.

Correct Answer is D
Explanation
A. The cervix being effaced is not represented by the -1 notation in a vaginal examination. Effacement is usually expressed as a percentage.
B. The -1 notation does not represent cervical dilation. Dilation is measured in centimeters.
C. The presenting part being 1 cm below the ischial spines is not correct. In the station system, if the presenting part is above the ischial spines, it is represented by a negative number. A -1 station indicates that the presenting part is 1 cm above the ischial spines.
D. The presenting part is 1 cm above the ischial spines is the correct interpretation.

Explanation
Increase the oxytocin infusion to 13 mu/min:
Anticipated: This action is anticipated. Adjusting the oxytocin infusion rate may be appropriate based on the progress of labor and the response to the current infusion rate.
Place client in a side-lying position:
Anticipated: Placing the client in a side-lying position is an anticipated action. This position can enhance fetal oxygenation and blood flow, especially if there are concerns about fetal well-being.
Initiate a bolus of primary IV fluids:
Anticipated: Initiating a bolus of primary IV fluids is an anticipated action. Adequate hydration is important during labor, and a bolus may be initiated if there are signs of dehydration or as part of the overall management plan.
Apply oxygen at 10 L/Min via a venturi mask:
Anticipated: Applying oxygen at 10 L/min via a venturi mask is an anticipated action. Oxygen may be administered to the mother to improve oxygenation and, consequently, fetal oxygenation.
Perform sterile vaginal examination (SVE):
Contraindicated: There is no indication for a sterile vaginal examination (SVE) at this time based on the information provided. Frequent unnecessary SVEs can increase the risk of infection.
Assign a Bishop score:
Nonessential: Assigning a Bishop score is not essential at this point. The client's cervical status was assessed during admission, and the current focus is on monitoring the progress of labor with oxytocin.
Perform an amniotomy:
Anticipated: Depending on the clinical situation, performing an amniotomy (artificial rupture of membranes) may be anticipated as part of the labor induction process. However, the decision should be based on the overall assessment and progress of labor.
