The first sign of hypovolemic shock from postpartum hemorrhage is likely to be:

Wash hands before touching each baby. This is because hand hygiene is the most effective way to prevent infection transmission in the nursery. Hand hygiene should be performed before and after every patient contact, as well as before and after wearing gloves or handling equipment. Hand hygiene can be done by washing hands with soap and water or using alcohol-based hand rubs.

Choice A is not correct because adjusting room temperature between 75°F and 80°F is not a measure to protect newborns from infection. The room temperature should be maintained within a comfortable range for newborns, but it does not affect infection risk.

Choice B is not correct because wearing a disposable gown when giving infant care is not a measure to protect newborns from infection. Disposable gowns are part of contact precautions, which are used for patients with known or suspected infections that can be transmitted by direct or indirect contact. They are not necessary for routine infant care.

Choice C is not correct because keeping the newborn dressed warmly is not a measure to protect newborns from infection. Keeping the newborn dressed warmly can help prevent heat loss and hypothermia, but it does not affect infection risk.

To check for postpartum hemorrhage.

This is because postpartum hemorrhage is a serious and potentially life-threatening complication that can occur within 24 hours of birth or later. It is defined as a blood loss of more than 500 mL in a vaginal delivery or more than 1000 mL in a cesarean delivery. The most common cause of postpartum hemorrhage is uterine atony, which is the failure of the uterus to contract after delivery. Other causes include lacerations, retained placental fragments, coagulation disorders, and uterine rupture. Monitoring the vital signs, especially blood pressure, and pulse, can help detect signs of hypovolemia due to blood loss. Other signs include pale skin, cold and clammy extremities, delayed capillary refill, decreased urine output, and altered mental status.

Choice B is not correct because determining if the mother's milk is coming in is not the primary rationale for monitoring a new mother every 15 minutes for the first hour after delivery. Milk production usually begins around 48 to 72 hours after delivery and is influenced by hormonal changes, breastfeeding frequency, and maternal health. Although breastfeeding support is important for postpartum care, it is not a priority over checking for postpartum hemorrhage.

Choice C is not correct because monitoring the mother's blood pressure to note any elevations is not the primary rationale for monitoring a new mother every 15 minutes for the first hour after delivery. Elevated blood pressure can indicate gestational hypertension or preeclampsia, which are serious conditions that can affect postpartum women. However, these conditions are more likely to cause symptoms such as headache, blurred vision, epigastric pain, and proteinuria⁴.

Moreover, blood pressure may not be a sensitive indicator of blood loss and may remain normal until a significant amount of blood is lost¹.

Choice D is not correct because answering questions the new parents may have is not the primary rationale for monitoring a new mother every 15 minutes for the first hour after delivery. Although providing education and support to the new parents is an essential part of postpartum care, it is not a priority over checking for postpartum hemorrhage. The new parents may have questions about infant care, feeding, contraception, recovery, and other topics that can be addressed during the postpartum period.
