A nurse is caring for a client in labor who has an epidural in place and is on continuous internal monitoring with a fetal scalp electrode and intrauterine pressure catheter.

The nurse notes a strong contraction on the monitor and the client reports nausea accompanied by an urgent need to have a bowel movement.

Which of the following assessments is the nurse's highest priority?

Choice A rationale

Consuming 27 mg of iron daily is within the recommended intake for pregnant individuals, which is typically around 27 mg per day. Iron is crucial for fetal growth and preventing maternal anemia, and this intake level supports healthy pregnancy outcomes, indicating a reduced risk factor.

Choice B rationale

Consuming 300 mg of caffeine daily is considered a high-risk lifestyle factor during pregnancy. High caffeine intake is associated with an increased risk of miscarriage, preterm birth, and low birth weight infants. The recommended limit for pregnant individuals is generally below 200 mg per day to mitigate these risks.

Choice C rationale

Consuming 3 L (101 oz) of water daily is a healthy practice during pregnancy. Adequate hydration is essential for maintaining blood volume, amniotic fluid levels, and preventing constipation and urinary tract infections. This intake level supports maternal and fetal health.

Choice D rationale

Consuming 400 mcg of folate daily is the recommended intake for pregnant individuals, particularly in the periconceptional period. Folic acid supplementation significantly reduces the risk of neural tube defects in the fetus, promoting a healthy pregnancy outcome and indicating a reduced risk factor.

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.
