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?

A nonstress test (NST) is a test in pregnancy that measures fetal heart rate in response to movement and contractions²³. A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations³⁴. An acceleration is defined as an increase in the fetal heart rate of at least 15 beats per minute above the baseline for at least 15 seconds²³⁴.
A nonstress test can be affected by uterine contractions, which can cause fetal heart rate decelerations or reduced variability²³. Uterine contractions can also indicate preterm labor or placental abruption, which are serious complications that require intervention². Therefore, if the nurse observes three or more uterine contractions within a 20-minute period during a nonstress test, they should intervene by notifying the provider, assessing the patient for signs of labor or bleeding, and preparing for further evaluation or treatment²⁵.

The other options are not correct because they do not require intervention by the nurse:
a) One acceleration of the FHR within a 20-min period is not enough to meet the criteria for a reactive nonstress test, but it does not indicate fetal distress or compromise. The nurse should continue monitoring the fetal heart rate for another 20 minutes or until two accelerations are observed²³⁴.
b) Uterine contractions lasting 20 to 30 seconds each are normal and expected during pregnancy, especially in the third trimester. They are called Braxton Hicks contractions and they help prepare the uterus for labor. They are usually painless and irregular, and do not cause cervical changes. They do not require intervention by the nurse unless they become frequent, intense, or painful².
d) An FHR that peaks 20 beats above the baseline is considered an acceleration and is a sign of fetal well- being. It does not require intervention by the nurse unless it is associated with decelerations or reduced variability²³⁴.

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 .
