Final answer:
True labor progresses in a positive feedback loop with contractions becoming more frequent and powerful during the latent phase of stage 1.
Step-by-step explanation:
Characteristics of latent phase contractions, stage 1
True labor progresses in a positive feedback loop in which uterine contractions stretch the cervix, causing it to dilate and efface, or become thinner. When labor begins, uterine contractions may occur less frequently and last for a shorter duration, but as the stage progresses, contractions become more frequent and last longer. Latent phase contractions are regular, do not abate with hydration or rest, and they become more frequent and powerful with time.
