单项选择题
Which of the following would the nurse expect to assess as presumptive signs of pregnancy
A. Amenorrhea and quickening.
B. A positive pregnancy test and a fetal outline.
C. Braxton Hicks contractions and Hegar’s sign.
D. Uterine enlargement and Chadwick’s sign.
答案
参考答案：A
解析：Presumptive signs, such as amenorrhea and quickening, are mostly subjective and may be indicative of other conditions or illnesses. Probable signs are objective but nonconclusive indicators--for example, uterine enlargement, Chadwick’s sign, a positive pregnancy test, Braxton Hicks contractions, and Hegar’s sign. Positive signs and objective indicators such as fetal outline on ultrasound confirm pregnancy.
