The nurse is reviewing the cardinal maneuvers of labor and birth with a group of nursing students. Which maneuver will immediately follow the birth of the baby's head?

Correct Answer: A

Rationale: After the baby's head is born, the immediate next step is the expulsion of the baby's body. This is because the expulsion maneuver refers to the delivery of the rest of the baby's body following the birth of the head. Restitution, internal rotation, and external rotation occur before the birth of the baby's head and are part of the cardinal movements of labor and birth. Restitution involves the realignment of the baby's head with their body after the head is born. Internal rotation refers to the baby's head turning to navigate through the birth canal. External rotation involves the baby's head turning back to its original position after delivery. So, the correct answer is A (Expulsion), as it directly follows the birth of the baby's head.

Correct Answer: A

Rationale: The correct answer is A because a patient in transition with contractions every 2 minutes lasting 90 seconds each is experiencing very intense and frequent contractions, indicating high uterine activity. Discontinuing oxytocin infusion is crucial in this scenario to prevent hyperstimulation, which can lead to fetal distress or uterine rupture. Choice B is incorrect because the patient is in early labor and the contractions are less frequent and less intense compared to the correct answer. Choice C is incorrect as the patient in active labor with contractions every 3 minutes lasting 60 seconds each is not as intense as the patient in transition in the correct answer. Choice D is incorrect because although the contractions are frequent and lasting longer, the intensity described in choice A is more concerning and requires immediate discontinuation of oxytocin infusion.

Correct Answer: C

Rationale: The correct answer is C: Persistent fetal bradycardia below 100 bpm. This is crucial because it indicates fetal distress and requires immediate intervention to prevent potential harm to the baby. Bradycardia below 100 bpm may indicate inadequate oxygen supply to the fetus, necessitating urgent action. Maternal vital signs in choices A and B are within normal ranges. Choice D, decreased intensity of uterine contractions, while important, is not as critical as fetal bradycardia in this scenario.

Correct Answer: A

Rationale: The correct answer is A because the priority intervention for a patient receiving oxytocin infusion for labor augmentation is to monitor fetal heart rate and uterine contractions. This is essential to ensure the safety of both the mother and the baby. Increasing the rate of Pitocin infusion (B) can lead to hyperstimulation and fetal distress. Providing oxygen and changing position (C) may be helpful in some situations but are not the priority. Stopping the Pitocin infusion (D) should only be done if there are signs of fetal distress or other complications.

Correct Answer: C

Rationale: The correct answer is C: Posterior fontanel. When a vacuum extractor is used during birth, it can cause swelling or molding of the baby's head, which may affect the assessment of the posterior fontanel. This fontanel is an important landmark for determining head size and shape. Swelling or molding can make it difficult to accurately assess the fontanel's size and shape, potentially impacting the overall assessment of the newborn's head. A: The anterior fontanel is not typically affected by the use of a vacuum extractor. B: The coronal suture lines are not directly impacted by the vacuum extractor. D: The biparietal diameter can still be measured accurately even with molding caused by the vacuum extractor.
