A nurse is caring for a client who is in active labor and is receiving oxytocin via IV infusion. The nurse has applied an internal fetal heart monitor and recognizes an early deceleration of the fetal heart rate tracing. Which of the following actions should the nurse take?

Choice A rationale: Flat areola without breast bud indicates immature breast tissue development, a marker of preterm gestational age due to incomplete fetal maturation of secondary sexual characteristics.

Choice B rationale: Maternal hormones influence neonatal breast tissue temporarily, but absence of bud reflects developmental immaturity rather than decreased maternal hormones during pregnancy.

Choice C rationale: Congenital anomalies involve structural malformations, not absence of breast bud, which is a normal developmental stage in preterm infants rather than a pathological anomaly.

Choice D rationale: Ambiguous secondary sex characteristics refer to atypical genital or pubertal development, not neonatal breast tissue maturity, making this unrelated to the flat areola finding.

Choice A rationale:

The nurse should not measure the abdominal circumference at the level of the newborn's umbilicus every 12 hr because this action does not address the specific problem presented in the scenario, which is abdominal distention and bloody stools. Measuring abdominal circumference is typically done to assess for growth and may not provide valuable information in this situation.

Choice B rationale:

Inserting an orogastric decompression tube with low wall suction is the appropriate action for a newborn with abdominal distension and bloody stools. This intervention can help decompress the gastrointestinal tract, reducing abdominal distention, and possibly preventing further complications.

Choice C rationale:

Providing the newborn with an iron-rich formula containing vitamin B12 every 2 hr is not indicated based on the information provided in the scenario. The newborn's symptoms are suggestive of gastrointestinal issues, and this intervention may not address the underlying cause.

Choice D rationale:

Administering nitric oxide inhalation therapy to the newborn is not appropriate in this context. Nitric oxide inhalation therapy is typically used for conditions like persistent pulmonary hypertension in the newborn, and there is no indication for its use in this case.
