Final answer:
After delivery, the maternal pulse and vital signs usually stabilize as the body adjusts to the postpartum period, with uterine contractions and involution helping the uterus return to its pre-pregnancy size.
Step-by-step explanation:
What occurs to the maternal pulse after delivery is an important aspect of the postpartum period, during which the mother's body returns to a non-pregnant state. After childbirth, the body undergoes several physiological changes, including further uterine contractions to help the uterus return to its pre-pregnancy size, a process known as involution. These contractions also aid in reducing blood loss from the site where the placenta was attached. The delivery of the placenta signifies the beginning of the postpartum period, which lasts approximately 6 weeks. It is additionally facilitated by breastfeeding, as it stimulates the production of milk and helps in contracting the uterus. During this time, it is usual for the maternal pulse and other vital signs to stabilize as the body adjusts after the stress of labor and delivery.
