A nurse is caring for a client who has maternal hypotension following the placement of an epidural. 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.

The correct answer is choice A, administer broad-spectrum antibiotics.

Choice A rationale:

Administering broad-spectrum antibiotics is crucial for a newborn with a myelomeningocele that is leaking cerebrospinal fluid to prevent infection. The leaking of cerebrospinal fluid can increase the risk of meningitis, which is an infection of the membranes covering the brain and spinal cord. Broad-spectrum antibiotics are used as a prophylactic measure to reduce this risk.

Choice B rationale:

Monitoring the rectal temperature every 4 hours is important for detecting fever, which could indicate infection. However, it is not the most immediate action required for a newborn with a leaking myelomeningocele. The priority is to prevent infection through the administration of antibiotics.

Choice C rationale:

Cleansing the site with povidone-iodine is not recommended for a myelomeningocele because it can be toxic to the exposed neural tissue. Instead, the area should be covered with a sterile saline dressing to protect the site and prevent drying and further damage to the neural tissue.

Choice D rationale:

While surgical closure is necessary for a newborn with myelomeningocele, it is typically performed within 24 to 48 hours after birth, not after 72 hours. Early closure is essential to reduce the risk of infection and further damage to the exposed spinal cord and nerves.
