The 1-day postpartum patient shows a temperature elevation, cough, and slight shortness of breath on exertion. Based on these symptoms, the nurse should:

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.

Sudden infant death syndrome (SIDS) is the sudden and unexplained death of an infant under one year of age. SIDS is more likely to occur when infants sleep on their stomachs or sides, or when they are propped up with pillows or other soft bedding. These positions can interfere with the infant's breathing and increase the risk of suffocation or overheating .

Choice A is incorrect because gastroesophageal reflux (GER) is a common condition in infants that causes them to spit up frequently after feeding. GER does not increase the risk of SIDS and can be managed by feeding smaller amounts, burping the infant often, and keeping them upright for a while after feeding.

Choice C is incorrect because apnea episodes are brief pauses in breathing that occur normally in infants, especially during sleep. Apnea episodes do not increase the risk of SIDS and usually resolve by six months of age.

Choice D is incorrect because sleeping for short intervals is normal for newborns, who need to feed frequently during the day and night. Sleeping for short intervals does not increase the risk of SIDS and will gradually change as the infant grows older.
