单项选择题
At what gestational age would a primigravida expect to feel "quickening"（）
A. 12 weeks.
B. 16 to 18 weeks.
C. 20 to 22 weeks.
D. By the end of the 26th week.
答案
参考答案：C
解析：
It’s important for the nurse to distinguish between a client who is having her first baby and one who has already had a baby. For the client who is pregnant for the first time, quickening occurs around 20 to 22 weeks. Women who have had children will feel quickening earlier, usually around 18 to 20 weeks, because they recognize the sensations.
