A nurse is assessing a client who is at 38 weeks of gestation. Upon admission 2 hours ago, the client had irregular contractions, was dilated 2 cm, and was at -1 cm station. Which of the following findings indicates progression in labor?

Choice A rationale True labor contractions persist and often intensify with activity, such as walking, because physical exertion promotes the release of oxytocin. In contrast, Braxton Hicks or false labor contractions typically diminish or cease with ambulation. Therefore, contractions persisting with walking indicate the cervical changes characteristic of progression into the active phase of labor. Choice B rationale Urinary frequency is a common discomfort throughout the third trimester of pregnancy due to the pressure of the enlarged uterus on the bladder. While present, it is not a specific indicator of the progression of labor from the latent to the active phase, which is characterized by measurable changes in cervical dilation and effacement. Choice C rationale Increased blood-tinged vaginal mucus, known as "bloody show," results from the cervical capillaries breaking as the cervix effaces and dilates. While this indicates cervical change, the most definitive sign of labor progression is a change in the frequency, duration, and intensity of contractions coupled with measurable descent or cervical dilation increase. Choice D rationale The station is the relationship of the presenting part to the ischial spines (zero station). The client's initial station was -1 cm. A change to -3 cm station indicates the fetus has moved up and away from the ischial spines, which signifies regression, or higher negative numbers, in the engagement, not the desired progression into the maternal pelvis.
