A nurse is caring for a client who is 12 hours postpartum and has a fourth-degree laceration of the perineum. The nurse should take which of the following actions?

Breast development is a normal part of fetal and neonatal growth. It occurs in stages, starting before birth and continuing during puberty and adulthood. Breast development is influenced by hormones, such as estrogen and progesterone, that are produced by the ovaries or the placenta¹².
Breast development in newborns can vary depending on the gestational age, sex, weight, and exposure to maternal hormones. Some newborns may have palpable breast tissue at birth, while others may develop it later in the first weeks of life. Some newborns may also secrete milk from their breasts, which is called witch's milk or neonatal galactorrhea. This is a harmless and temporary phenomenon that usually resolves within a few weeks without treatment³⁴.
The degree of breast development in newborns can be assessed by using a scoring system that ranges from 0 to 5, based on the size of the areola (the dark area around the nipple) and the presence of a bud (a small lump of glandular tissue under the areola). The scoring system is as follows³:
- Score 0: No breast tissue; flat areola with no bud
- Score 1: Breast tissue < 5 mm; flat areola with no bud
- Score 2: Breast tissue 5 to 10 mm; flat areola with no bud
- Score 3: Breast tissue > 10 mm; raised areola with no bud
- Score 4: Breast tissue > 10 mm; raised areola with bud
- Score 5: Breast tissue > 10 mm; raised areola with large bud
The average score for term newborns is 2.5 for girls and 2.0 for boys. The score tends to be higher for heavier babies and lower for lighter babies. The score also tends to be higher for babies who were exposed to higher levels of maternal hormones during pregnancy, such as those whose mothers had diabetes, preeclampsia, or multiple gestation³⁴.
A score of 0 indicates that there is no breast tissue at all, and the areola is flat with no bud. This finding can indicate preterm gestational age, as breast development usually starts before birth and progresses with increasing gestational age. Preterm newborns may have delayed or incomplete breast development due to insufficient exposure to maternal hormones or immature development of their own hormonal system³⁵.
Therefore, the nurse should identify this finding as indicating preterm gestational age and monitor the newborn for any other signs of prematurity, such as low birth weight, small head size, thin skin, low body temperature, respiratory distress, or feeding difficulties. The nurse should also provide appropriate care and support to the newborn and the parents according to the hospital protocol³⁵.

- b) Ambiguous secondary sex characteristics are physical features that do not clearly match the typical male or female pattern, such as genitalia, hair distribution, or voice pitch. They can be caused by genetic disorders, hormonal imbalances, or environmental influences. Ambiguous secondary sex characteristics do not affect breast development in newborns, as breast tissue is present in both sexes and is influenced by maternal hormones rather than sex hormones¹ .
- c) Decreased maternal hormones during pregnancy can affect breast development in newborns, but not in the way described. Decreased maternal hormones during pregnancy can cause lower breast scores in newborns, as they may have less stimulation of their breast tissue from the placenta. However, this does not mean that they have no breast tissue at all or a flat areola with no bud. They may still have some degree of breast development depending on their gestational age, sex, weight, and exposure to their own hormones³⁴.
- d) Congenital anomaly is a term that refers to any structural or functional abnormality that is present at birth. Congenital anomalies can affect any part of the body and can have various causes, such as genetic mutations, chromosomal abnormalities, infections, drugs, or environmental factors. Congenital anomalies can affect breast development in newborns, but not in the way described. Congenital anomalies that affect breast development in newborns usually cause abnormal or absent nipples or breasts, such as nipple hypoplasia (underdeveloped nipples), athelia (absence of nipples), amastia (absence of breasts), or polymastia (extra breasts). These anomalies do not cause a flat areola with no bud .

Neonatal abstinence syndrome (NAS) occurs in newborns who were exposed to addictive substances, such as opioids, during pregnancy. Infants with NAS may experience withdrawal symptoms and can be hypersensitive to stimuli. Therefore, it is important to minimize unnecessary handling to help reduce stimulation and discomfort for the newborn.

Option a) Swaddling the newborn with his legs extended may increase discomfort for a newborn with NAS. It is often recommended to swaddle newborns with NAS in a flexed position to provide a sense of security and comfort.

Option b) Maintaining eye contact during feedings may be overwhelming for a newborn with NAS. Maintaining a calm, quiet environment during feedings can help reduce overstimulation and improve feeding success.

Option c) Scheduling larger volume feedings at less frequent intervals may not be appropriate for a newborn with NAS. These infants may have poor feeding tolerance and may benefit from smaller, more frequent feedings to avoid overwhelming their gastrointestinal system.

Therefore, option d) Plan care to minimize handling of the newborn is the correct action to take when caring for a newborn with neonatal abstinence syndrome. It helps reduce stimulation and discomfort for the newborn.
