  51. Describe the first stage of labor.
    Cervical effacement and dilation occur in the first stage of labor, or stage of dilation.

    Active Phase: Dilation is more rapid and begins around 4-6cm. Discomfort usually increases as the pace of labor picks up. 

    Transition: Starting at 7-8cm, bloody show often increases with completion of cervical dilation. Here is where the urge to push starts to occur, they become anxious and irritable, or helpless.
  53. Describe the Second stage of labor
