Postpartum Fundal Height Calculation

During the postpartum care of a new mother, the nurse assesses her after a vaginal delivery. The patient is experiencing a total blood loss of 500 mL during the delivery process. The nurse has been monitoring her vital signs, and they are stable. However, to ensure proper recovery and prevent complications, it is essential to promote health in the postpartum period.

At this stage, the nurse knows that uterine involution is vital for the mother’s recovery. The average rate of involution is approximately 1 cm per day. If the fundal height of the uterus is measured at 2 cm above the umbilicus on day 1 postpartum, the expected height of the fundus on day _____ postpartum should be documented.
