The nurse anticipates the vaginal delivery of a client who has been induced for macrosomia. The provider asks the nurse to apply suprapubic pressure. The nurse knows that suprapubic pressure is applied:

The most common cause of excessive blood loss after childbirth is the failure of the uterine muscle to contract firmly, which is also known as uterine atony. If the uterus does not contract effectively after delivery, it cannot properly close off the blood vessels that were connected to the placenta, leading to heavy bleeding. Uterine atony can occur due to various factors, such as prolonged labor, multiple births, or the use of certain medications during labor.
Other causes of excessive blood loss after childbirth include retained placental fragments, vaginal or vulvar hematomas, or unrepaired lacerations of the vagina or cervix, but these are less common than uterine atony.

The most common indication for a vacuum-assisted delivery is a prolonged second stage of labor, which means that the mother has been pushing for an extended period without effective descent of the fetal head. The vacuum can help to provide traction to the fetal head and assist with delivery.
Option A is incorrect because a vacuum-assisted delivery is not indicated for the prevention of fetal abnormalities.
Option B is incorrect because a vacuum-assisted delivery is not indicated for the prevention of maternal hemorrhage.
Option D is incorrect because a prolonged first stage of labor is not an indication of
vacuum-assisted delivery. In this case, other interventions, such as augmentation of labor with oxytocin, may be used.
