参考答案：A
解析：Most clients' membranes will rupture before the time of delivery, but approximately 12% will rupture before the onset of labor. Premonitory signs of labor include Braxton Hicks contractions; lightening (which usually occurs 2 weeks before labor begins in a first pregnancy); cervical changes, including the softening and ripening; bloody mucus vaginal discharge (bloody show); rupture of the membranes; a sudden burst of energy; weight loss; increased backache; and diarrhea, indigestion, nausea, or vomiting.
