Final answer:
For a postpartum client who is bottle-feeding, menstruation typically returns about 6 weeks after childbirth, but this can vary from person to person.
Step-by-step explanation:
A postpartum client who is bottle-feeding her neonate may experience the return of menstruation at varying times. For mothers who are not breastfeeding, menstruation can return as soon as 6 weeks postpartum, but this can vary widely among individuals. It is important to note that breastfeeding mothers may see a delay in the return of menstruation, particularly due to the hormonal processes involved in lactation. Once breastfeeding is stopped, the return of menstruation can also be expected within a few weeks to months, depending on individual hormonal responses. However, for bottle-feeding mothers, menstrual cycles typically resume earlier as the body adjusts back to its non-pregnant state without the interference of breastfeeding hormones.
