A nurse is caring for a female client, age 29, at 39 weeks of gestation in the intrapartum unit following spontaneous rupture of membranes.

Complete the following sentence by using the lists of options.
The client is at risk for developing

_________

as evidenced by

__________

.

The nurse should further evaluate respiratory characteristics and muscle tone to determine if the newborn is experiencing a complication.

Rationale for correct answers
Respiratory characteristics are critical to assess because irregular and shallow breathing in a newborn can indicate neurological or respiratory dysfunction. Normal neonatal respiratory rate ranges from 30 to 60 breaths per minute with regular pattern; deviations may signal distress or central nervous system issues. Muscle tone evaluation is essential since increased tone with tremors suggests possible neurologic irritability or withdrawal. Normal newborn muscle tone should be moderate, neither hypotonic nor hypertonic, with symmetrical movement. These signs correlate with the high-pitched cry, tremors, and exaggerated reflexes noted, which may indicate neurological complications such as withdrawal syndrome or hypoxic-ischemic encephalopathy.

Rationale for incorrect answers
Heart rate (A) is important but was not reported abnormal; normal neonatal heart rate ranges from 120 to 160 beats per minute and the absence of murmurs suggests no cardiac compromise. Temperature (C) is less urgent as mucous membranes are moist and skin warm and dry, indicating stable thermoregulation; normal newborn temperature is 36.5–37.5°C. Feeding patterns (D) appear adequate with no difficulty reported, making this less immediately concerning.

Rationale for incorrect answers
Moro reflex (A) and Babinski reflex (B) are both present and exaggerated, which may be reactive but less specific for immediate concern than muscle tone abnormalities. Skin color (D) is normal without cyanosis or jaundice, reducing the likelihood of hypoxia or hemolytic issues.

Take home points

• Respiratory pattern irregularities in newborns may indicate neurological or respiratory dysfunction.
• Abnormal muscle tone and tremors are key signs of potential neurological complications.
• Normal heart rate, temperature, feeding, and skin color reduce likelihood of cardiac or systemic illness.
• Reflex exaggeration alone is less specific than muscle tone and respiratory changes for early complication detection.

Choice A rationale

Acrocyanosis, characterized by bluish discoloration of the hands and feet, is a common and usually benign finding in newborns, especially shortly after birth due to immature peripheral circulation. It does not typically indicate neonatal abstinence syndrome, which is a neurological and systemic hyperexcitability response to opioid withdrawal.

Choice B rationale

Hypotonia, or decreased muscle tone, is generally a sign of central nervous system depression or neuromuscular disorder. In contrast, newborns with neonatal abstinence syndrome typically exhibit hypertonia, characterized by increased muscle tone, tremors, and hyperreflexia, due to the overstimulation of the central nervous system following cessation of maternal opioid exposure.

Choice C rationale

An exaggerated Moro reflex, characterized by an overly robust and prolonged startle response, is a common manifestation of central nervous system irritability seen in newborns experiencing neonatal abstinence syndrome. This hyperreflexia is a direct result of the withdrawal symptoms, indicating an overactive nervous system in response to the absence of the previously supplied opioid.

Choice D rationale

Tachypnea, or rapid breathing, is a frequent finding in newborns with neonatal abstinence syndrome. This symptom is often attributed to central nervous system irritability and increased metabolic demand associated with withdrawal, leading to respiratory distress. The respiratory rate often exceeds the normal range of 30-60 breaths per minute.

Choice E rationale

A shrill-pitched cry, often described as inconsolable or high-pitched, is a classic and distinctive symptom of neonatal abstinence syndrome. This abnormal cry pattern is indicative of central nervous system irritation and dysregulation, reflecting the newborn's discomfort and hyperirritability stemming from opioid withdrawal. This cry often differs from a typical hunger or discomfort cry.
