An uncomplicated full-term pregnancy brings a 29-year-old expectant mother to the obstetric triage unit experiencing painful, regular uterine contractions. Arrange the following stages and phases of a normal obstetric labor in the correct chronological order, starting from the onset of true labor and concluding with the immediate postpartum recovery period.
- 1Latent phase of the first stage of labor (gradual cervical dilation typically up to 6 cm)
- 2Active phase of the first stage of labor (rapid cervical dilation from 6 cm to 10 cm)
- 3Second stage of labor (from complete cervical dilation to the delivery of the neonate)
- 4Third stage of labor (from the delivery of the neonate to the delivery of the placenta)
- 5Fourth stage of labor (initial 1 to 2 hours of physiological adaptation postpartum)
Cevap
The correct sequence is: Latent phase of the first stage, Active phase of the first stage, Second stage, Third stage, and Fourth stage.
The physiological progression of labor follows a predictable chronological sequence. It begins with the first stage, which is divided into the slower latent phase followed by the more rapid active phase. Once the cervix is completely dilated (10 cm), the second stage begins, culminating in the delivery of the fetus. The third stage involves the delivery of the placenta. Finally, the fourth stage refers to the immediate 1 to 2 hour postpartum period of physiological stabilization.
