The nurse is caring for a woman in labor. The woman becomes irritable, restless, complains of nausea, and has heavier show. The membranes just ruptured spontaneously. The nurse understands that this indicates


• During the transition phase of the first stage of labor, the maximum cervical dilation of 8–10 cm occurs and contractions reach their peak of intensity, occurring every 2–3 minutes with a duration of 60–90 seconds.

• During the transition phase, the woman may experience intense discomfort, possibly accompanied by nausea and vomiting. Because of the intensity and duration of the contractions, she may experience a feeling of loss of control, anxiety, panic, and irritability. Since dilatation continues at a rapid rate, the membranes rupture and heavy show is present.

• Incorrect: An arrest of cervical dilation occurs when there is no progress in cervical dilation for more than 2 hours.

• Incorrect: An impending uterine rupture is preceded by a pathologic retraction ring and strong uterine contractions without any cervical dilatation.

• All other choices are incorrect because the patient is not experiencing a complication and the physician should not be notified.
