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

Heart rate is one of the vital signs that reflects the health and well-being of a newborn. It is measured by counting the number of heart beats per minute, either by listening to the chest with a stethoscope or by feeling the pulse at the wrist, elbow, or groin. Heart rate can vary depending on the newborn's activity level, temperature, and emotional state¹.
The normal range for heart rate in full-term newborns is 120 to 160 beats per minute. The heart rate may be slightly higher or lower depending on the newborn's age, weight, and gestational age. For example, premature newborns may have a higher heart rate than term newborns, and heavier newborns may have a lower heart rate than lighter newborns¹².
A heart rate that is too high (tachycardia) or too low (bradycardia) can indicate a problem with the newborn's heart function, oxygenation, or circulation. Some of the possible causes of abnormal heart rate in newborns are:

- Congenital heart defects: structural abnormalities of the heart that are present at birth and affect the blood flow through the heart and the body. They can cause cyanosis (bluish skin color), murmur (abnormal heart sound), poor feeding, or failure to thrive¹³.
- Arrhythmias: irregular or abnormal heart rhythms that can affect the electrical impulses that control the heartbeat. They can cause palpitations (feeling of skipped or extra beats), dizziness, fainting, or cardiac arrest¹³.
- Hypoxia: lack of oxygen in the blood or tissues that can affect the brain and other organs. It can be caused by respiratory distress, anemia, infection, or birth asphyxia. It can cause bradycardia, apnea (pauses in breathing), seizures, or coma¹⁴.
- Hypothermia: low body temperature that can affect the metabolism and organ function. It can be caused by exposure to cold environment, infection, or prematurity. It can cause bradycardia, lethargy, poor feeding, or hypoglycemia (low blood sugar)¹⁴.
- Sepsis: severe infection that can affect the whole body and cause inflammation and organ damage. It can be caused by bacteria, viruses, fungi, or parasites that enter the bloodstream from the mother, the umbilical cord, or the environment. It can cause tachycardia, fever, chills, poor feeding, or shock¹⁴.
Therefore, the nurse should report a heart rate of 72/min to the provider as an abnormal finding and monitor the newborn for any other signs of distress or illness. The provider may order further tests or treatments to determine the cause and severity of the low heart rate and prevent any complications.

The other findings are not findings that the nurse should report to the provider because they are within the
normal range for full-term newborns:
- a) Respiratory rate 55/min is within the normal range for respiratory rate in full-term newborns. The normal range for respiratory rate in full-term newborns is 40 to 60 breaths per minute. The respiratory rate may vary depending on the newborn's activity level, temperature and emotional state¹².
- b) Blood pressure 80/50 mm Hg is within the normal range for blood pressure in full-term newborns. The normal range for blood pressure in full-term newborns is 65 to 95 mm Hg for systolic pressure (the top number) and 30 to 60 mm Hg for diastolic pressure (the bottom number). The blood pressure may vary depending on the newborn's age, weight, and gestational age¹².
- c) Temperature 36.5°C (97.7°F) is within the normal range for temperature in full-term newborns. The normal range for temperature in full-term newborns is 36.5°C to 37.5°C (97.7°F to 99.5°F). The temperature may vary depending on the newborn's activity level, clothing, and environment¹².

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.
