a. Which assessment finding would best confirm this diagnosisA. A rigid abdomen.B. A soft, nontender uterus.C. Painful vaginal bleeding.D. Hypotension.
参考答案：B
解析：A soft, relaxed, nontender uterus accompanied by vaginal bleeding indicates placenta previa. A rigid abdomen indicates abruptio placentae, in which a normally implanted placenta in the upper uterine segment prematurely separates from its implantation site. In placenta previa, the placenta isn’t normally implanted, and the client shouldn’t feel pain when it begins to break away. Hypotension may indicate many conditions other than placenta previa. Also, bleeding with placenta previa may not be severe enough to cause hypotension.
