A nurse is assessing a client who is 6 hours postpartum and has endometritis. Which of the following findings should the nurse expect?

A newborn who is 1 hour old and has a respiratory rate of 50/min, a heart rate of 130/min, and an axillary temperature of 36.1°C (97°F) has normal vital signs for their age¹². However, the newborn is at risk of losing heat and developing hypothermia, which can cause serious complications such as hypoglycemia, metabolic acidosis, and respiratory distress³. Therefore, the nurse should take measures to prevent heat loss and maintain a neutral thermal environment for the newborn³⁴.
One of the effective ways to prevent heat loss in newborns is to apply a cap to their head. The head has a large surface area relative to the body mass and can account for up to 50% of heat loss in newborns³⁴. A cap can reduce heat loss through radiation, convection, and evaporation from the scalp³⁴. The cap should be dry, clean, and snug-fitting, and should not cover the eyes or ears of the newborn³⁴.

a) Giving the newborn a warm bath is not an appropriate action for the nurse to take. Bathing can increase heat loss through evaporation and conduction, especially if the water temperature is not optimal or the room temperature is too low³⁴. Bathing should be delayed until the newborn's temperature is stable and preferably after the first breastfeeding session³⁴.
b) Repositioning the newborn is not a sufficient action for the nurse to take. Repositioning may help reduce heat loss through conduction if the newborn is placed away from cold surfaces or objects, but it does not address heat loss through other mechanisms³⁴. Repositioning should be combined with other interventions, such as skin-to-skin contact, swaddling, or radiant warmers³⁴.
c) Obtaining an oxygen saturation level is not a relevant action for the nurse to take. Oxygen saturation is a measure of how much oxygen is carried by the hemoglobin in the blood. It is not directly related to temperature regulation or heat loss in newborns³⁴. Oxygen saturation should be monitored routinely in all newborns before discharge as part of screening for congenital heart disease, but it does not address the risk of hypothermia⁵.

Sore nipples are a common problem for breastfeeding mothers, especially in the first few days or weeks after delivery. They can cause pain, discomfort, and frustration, and may interfere with breastfeeding success and satisfaction. The most common cause of sore nipples is poor latch, which means that the newborn does not attach to the breast correctly and does not suckle effectively. Poor latch can result from various factors, such as improper positioning, tongue-tie, inverted or flat nipples, engorgement, or thrush.

The nurse should assess the newborn's latch while breastfeeding to identify and correct any problems that may cause sore nipples. The nurse should observe the following signs of a good latch:
- The newborn's mouth is wide open and covers most of the areola (the dark area around the nipple).
- The newborn's chin and nose touch the breast, and the cheeks are rounded and not dimpled.

- The newborn's tongue is visible under the lower lip and curls around the breast.
- The newborn's lips are flanged outwards and not tucked inwards.
- The newborn's jaw moves rhythmically and smoothly, and swallowing sounds are audible.
- The mother feels a gentle tugging sensation on the nipple, but no pain or pinching.

The nurse should also teach the mother how to achieve a good latch by using different positions, supporting the breast with her hand, tickling the newborn's lower lip with her nipple, and bringing the newborn to the breast when their mouth is wide open. The nurse should also encourage the mother to seek help from a lactation consultant or a peer support group if she has persistent or severe nipple pain.

a) Instructing the client to wait 4 hours between daytime feedings is not an appropriate action for the nurse to take. This may reduce nipple soreness temporarily, but it can also cause breast engorgement, milk supply reduction, mastitis, or poor weight gain in the newborn. The nurse should advise the client to feed the newborn on demand, usually every 1.5 to 3 hours during the day and every 3 to 4 hours at night.
b) Offering supplemental formula between the newborn's feedings is not an appropriate action for the nurse to take. This may interfere with breastfeeding initiation and establishment, as it can reduce the mother's milk supply, confuse the newborn's sucking pattern, increase the risk of nipple preference or rejection, and expose the newborn to potential allergens or infections. The nurse should support exclusive breastfeeding for the first six months of life, unless there is a medical indication for supplementation.
c) Having the client limit the length of breastfeeding to 5 minutes per breast is not an appropriate action for the nurse to take. This may not be enough time for the newborn to get enough milk, especially the hindmilk that is richer in fat and calories. It may also prevent proper drainage of the breast and lead to engorgement or mastitis. The nurse should advise the client to let the newborn feed until they are satisfied and release the breast on their own, which may take 10 to 20 minutes per breast on average.
