Which assessment findings may cause the nurse to suspect a brachial plexus injury?
The newborn has hypotonia
The newborn does not demonstrate the Moro reflex
The newborn cries continually
The newborn has tremors
The Correct Answer is B
Choice A reason:
The newborn has hypotonia. This is not a specific sign of brachial plexus injury, as hypotonia can have many other causes, such as genetic disorders, infections, or brain damage.
Hypotonia is a general term for low muscle tone or weakness, which can affect the whole body or specific parts.
Choice B reason:
The newborn does not demonstrate the Moro reflex. This is a sign of brachial plexus injury, especially if it affects only one arm. The Moro reflex is a startle response that causes the baby to throw out the arms and legs, then curl them in when startled. A brachial plexus injury can impair the nerve function in the shoulder, arm, or hand, leading to decreased movement or sensation in the upper extremity. If the baby does not show the Moro reflex on one side, it may indicate damage to the upper brachial plexus nerves (C5-C7), also known as Erb's palsy.
Choice C reason:
The newborn cries continually. This is not a specific sign of brachial plexus injury, as crying can have many other causes, such as hunger, discomfort, or colic. Crying is a normal way for babies to communicate their needs and feelings. Crying does not necessarily indicate pain from a brachial plexus injury, as infants' nerves behave differently from adults' and they may not experience much pain from this condition.
Choice D reason:
The newborn has tremors. This is not a specific sign of brachial plexus injury, as tremors can have many other causes, such as cold temperature, low blood sugar, or withdrawal from maternal medications. Tremors are involuntary movements of the muscles that can affect the whole body or specific parts. Tremors do not necessarily indicate nerve damage from a brachial plexus injury, as this condition usually causes weakness or paralysis of the affected muscles.

Correct Answer is D
Explanation
Choice A reason:
Injury sustained to the perineum during birth is not a perinatal injury, but a perineal injury. The perineum is the area between the anus and the genitals, and it can be torn or cut during vaginal delivery. This is a common complication that affects the mother, not the fetus or newborn.
Choice B reason:
Traumatic injury to the mother during pregnancy is not a perinatal injury, but a maternal injury. This can occur due to accidents, violence, or complications of pregnancy such as preeclampsia or placental abruption. This can affect the mother's health and well-being, and may also have consequences for the fetus or newborn.
Choice C reason:
Traumatic injury to a fetus is not a perinatal injury, but a fetal injury. This can occur due to external forces such as blunt trauma, penetrating trauma, or radiation exposure that affect the fetus in utero. This can cause fetal distress, bleeding, fractures, or organ damage.
Choice D reason:
Injury sustained surrounding birth is a perinatal injury. This occurs in the period shortly before, during, or after delivery. This can be a critical time when the baby has to transition from surviving off oxygen, blood, and nutrients from the mother to separating from the womb and breathing oxygen from the air. Perinatal injuries can include head injuries, nerve injuries, hemorrhages, fractures, or soft-tissue injuries that result from the forces of labor and delivery or medical interventions such as forceps or vacuum extraction. Perinatal injuries can lead to long-term neurodevelopmental challenges for the newborn.
Correct Answer is A
Explanation
Choice A reason:
Hypoglycemia is a common complication for newborns whose mothers have diabetes mellitus. This is because the newborn's pancreas produces excessive insulin in response to the high glucose levels in the mother's blood during pregnancy. After birth, the newborn's glucose levels drop rapidly, while the insulin levels remain high, resulting in hypoglycemia. The nurse should monitor the newborn's blood glucose levels and signs of hypoglycemia, such as jitteriness, lethargy, poor feeding, and temperature instability.
Choice B reason:
Decreased RBC is not a likely complication for newborns whose mothers have diabetes mellitus. In fact, these newborns may have increased RBC due to chronic fetal hypoxia caused by placental insufficiency. The nurse should monitor the newborn's hematocrit and signs of polycythemia, such as ruddy skin, jaundice, and respiratory distress.
Choice C reason:
Hyperbilirubinemia is not a likely complication for newborns whose mothers have diabetes mellitus. In fact, these newborns may have increased bilirubin levels due to hemolysis of excess RBC and delayed hepatic clearance. The nurse should monitor the newborn's serum bilirubin levels and signs of jaundice, such as yellow skin and sclera, poor feeding, and lethargy.
Choice D reason:
Hypercalcemia is not a likely complication for newborns whose mothers have diabetes mellitus. In fact, these newborns may have hypocalcemia due to decreased parathyroid hormone secretion and increased calcium binding to albumin. The nurse should monitor the newborn's serum calcium levels and signs of hypocalcemia, such as jitteriness, tremors, seizures, and cardiac arrhythmias.
