A 23-year-old primigravida client has a normal vaginal delivery. The next day, the nurse assesses the client's lochia for color, amount, and the presence of clots. Which of the following best describes lochia on the first postpartum day ？（）
A．Dark red (loehia rubra), large amount, with many clots.
B．Pink (lochia serosa), moderate amount, no clots.
C．White (lochia alba), scant amount, no clots.
D．Dark red (lochia rubra), moderate amount, with a few small clots.
参考答案：D
解析：
Lochia rubra is usually seen during the first 1 to 3 days. It should be moderate in amount and may include some small clots. Four to eight perineal pads are used daily on average. Heavy bleeding could be from uterine atony or retained placental fragments and therefore requires further investigation. Lochia serosa follows lochia rubra and lasts to about the 10th postpartum day. Lochia alba is seen from approximately the 11th to the 21st postpartum day.
