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:

When late decelerations are noted in the fetal heart rate (FHR) tracing, it indicates that the fetal oxygen supply may be compromised. The nurse should first change the client's position, such as moving her to the left lateral position or a hands-and-knees position, to improve uteroplacental blood flow and relieve pressure on the vena cava.

Choice B rationale:

Palpating the uterus to assess for tachysystole is not the priority action when late decelerations are observed. Tachysystole refers to excessively frequent uterine contractions and may contribute to fetal distress, but the immediate concern is addressing the decelerations.

Choice C rationale:

Increasing the client's IV infusion rate may not address the underlying cause of late decelerations. While maintaining hydration is important, it's not the first action to take in this situation.

Choice D rationale:

Administering oxygen at 10 L/min via a non-rebreather mask may be beneficial for the client and fetus, but it is not the first action to take. The nurse should address the position change first to improve oxygenation through better blood flow before considering supplemental oxygen.

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.
