A laboring client received meperidine IV one hour prior to delivery. Which of the following medications should the nurse have available to counteract the effects of this medication on the newborn?

Choice A rationale:

Hyporeactivity is not typically associated with neonatal abstinence syndrome (NAS) NAS is characterized by increased irritability and signs of withdrawal, which are opposite to a hypo- reactive state.

Choice B rationale:

An excessive high-pitched cry is a hallmark sign of neonatal abstinence syndrome. Babies exposed to drugs like methadone during pregnancy can experience withdrawal symptoms, including a distinct high-pitched cry.

Choice C rationale:

Acrocyanosis, a bluish discoloration of the extremities, is a common finding in newborns and is not specific to NAS. It is caused by immature peripheral circulation and usually resolves on its own.

Choice D rationale:

A respiratory rate of 50/min is within the normal range for a newborn and is not a sign of neonatal abstinence syndrome. NAS symptoms are related to drug withdrawal and not respiratory issues.

The correct answer is: A. Hemoglobin 12 g/dL.

Choice A reason:

Hemoglobin levels in newborns are expected to be significantly higher than in adults due to the physiological adaptation to life outside the womb. The normal range for a newborn’s hemoglobin is approximately 14 to 24 g/dL1234. A level of 12 g/dL is below the expected range and could indicate anemia or other underlying conditions that may require further investigation and intervention by the healthcare provider.

Choice B reason:

The glucose level in a newborn can vary, especially within the first few hours after birth. Normal blood glucose levels for a newborn 1 to 2 hours old can be as low as 25 mg/dL and can rise to adult levels (60-100 mg/dL) within the first few days5. A glucose level of 50 mg/dL in a 24-hour-old newborn falls within the acceptable range and would not typically require reporting to the provider unless accompanied by symptoms of hypoglycemia.

Choice C reason:

Bilirubin levels in newborns can be elevated due to the normal breakdown of fetal hemoglobin as the baby’s liver matures. Normal bilirubin levels for a newborn can range from 1.0 to 12.0 mg/dL6. A bilirubin level of 4 mg/dL is within the normal range for a 24-hour-old newborn and is not typically a cause for concern unless there are signs of jaundice or other symptoms.

Choice D reason:

The normal platelet count for a newborn ranges from 150,000 to 450,000/mm³7. A platelet count of 200,000/mm³ is well within the normal range for a newborn and would not need to be reported to the healthcare provider.
