Final answer:
Docusate sodium (Colace) is given to a postpartum client to prevent constipation by acting as a stool softener, helping to facilitate easier bowel movements. It does not stimulate FSH production, affect estrogen levels, dilate the cervix, or decrease uterine contractility.
Step-by-step explanation:
The purpose of giving docusate sodium (Colace) to a postpartum client is b. Prevent constipation. Postpartum women are at increased risk for constipation due to several factors, including the effects of pain medications, reduced physical activity, and the body's process of recovery after childbirth. Docusate sodium acts as a stool softener, making it easier for postpartum women to have bowel movements without straining, which is particularly important to avoid after giving birth.
Docusate sodium does not have effects such as stimulating FSH production, decreasing the levels of estrogens, dilating the cervix, or decreasing the inhibition of uterine contractility. These actions are unrelated to the mechanism of action of docusate sodium, and therefore, options a, c, and d are incorrect in the context of this question about postpartum care.
