Play is often considered a prerogative of children and only an occasional indulgence for adults. Its role in children's lives is generally recognized as an important part of 'being a child,' but it is not always clearly understood that play is an essential developmental mechanism.ots of Essays, Functions of Play in the Human Lifespan., LotsofEssays.com, http://www.lotsofessays.com/viewpaper/1693293.html (accessed October 19, 2015).
The First Stage of Labor. The first stage is the longest part of labor and can last up to 20 hours. It begins when your cervix starts to open (dilate) and ends when it is completely open (fully dilated) at 10 centimeters. When the cervix dilates from 0 to 3 or 4 centimeters, contractions get stronger as time progresses.
The average duration of latent phase in nulliparous and multiparous women is 6.4 and 4.8 hours, respectively. An abnormally long latent phase is defined as 20 hours for the nullipara and 14 hours for the multiparous woman. Active Phase: rapid change in the rate (slope) of cervical dilation occurs at 3 to 4 centimeters. Average duration of active labor (onset defined as 3cm dilation) in nulliparous and parous women was 6.4 and 4.6 hours, respectively.
