A 3-day-old infant who weighs 6 lb (2722 g) is fed formula every 4 hours. Newborns require about 73 mL of fluid per pound (454 g) of body weight each day. In light of this information,approximately how much formula should the infant receive at each feeding?

A) Assess the woman's fundus and massage it if boggy:
A saturated pad within 15 minutes after delivery suggests a hemorrhage, and the first priority in this situation is to assess the fundus. If the fundus is boggy (soft and not contracted), it is a sign of uterine atony, which is the most common cause of postpartum hemorrhage. Massaging the fundus helps stimulate uterine contraction, which can help stop the bleeding.

B) Assess the woman's pulse and BP for signs of hypovolemic shock:
While it is important to monitor vital signs for signs of hypovolemic shock (e.g., increased heart rate, decreased blood pressure, and pale skin), this action would not be the first priority in managing a postpartum hemorrhage. The immediate focus should be on stopping the bleeding by addressing uterine atony. Hypovolemic shock assessment is important, but it comes after the initial steps of managing hemorrhage.

C) Call the woman's primary healthcare provider:
Calling the provider may be necessary if the bleeding does not stop after initial interventions. However, it should not be the first action. The nurse should first assess the uterus and attempt to stop the bleeding by massaging the fundus before calling the provider.

D) Begin an IV infusion of Ringer's lactate solution and administer oxytocin:
Starting an IV infusion and administering oxytocin may be part of the treatment for postpartum hemorrhage, but the first action should be to assess and manage the fundus. Oxytocin can help contract the uterus, but massaging the fundus is the immediate intervention. Intravenous fluids and medications should be initiated once the uterus is assessed and massaged, especially if bleeding persists.

A) Apply an ice pack to the perineum:
For a second-degree perineal laceration sustained during delivery, ice application is an important intervention within the first 24 hours to reduce swelling, pain, and inflammation in the perineal area. Ice packs help constrict blood vessels, decrease tissue edema, and provide analgesic effects. This intervention is most effective immediately after delivery and within the first 2-4 hours to help manage pain and swelling at the site of the laceration.

B) Teach the woman to insert nothing into her rectum:
While it is true that women with perineal lacerations should avoid rectal trauma or anything inserted into the rectum (e.g., rectal thermometers, suppositories) for a period of time, this is not the most urgent or immediate action for this patient. The primary concern at this point is managing the acute symptoms related to the laceration (e.g., swelling, pain), which is best managed with ice packs and other measures. Teaching about avoiding rectal insertion would be important later in the postpartum period.
C) Advise the woman to sit on a pillow:
While sitting on a pillow can reduce pressure on the perineum and help with comfort, it is not the most immediate intervention for this woman, especially in the first few hours postpartum. The priority should be addressing swelling and pain associated with the perineal laceration, which is best managed with ice, as it helps with the acute management of the injury.

D) Advise the woman to use sitz bath after each void:
A sitz bath can be helpful for perineal healing in the postpartum period, but it is typically recommended after the first 24 hours post-delivery, after the initial swelling has gone down. During the first few hours to days postpartum, ice packs are generally the preferred intervention to manage swelling and pain, while sitz baths are often advised later to promote comfort, healing, and circulation in the perineum.
