What is a sign that a newborn may be at risk for meconium aspiration syndrome?

Choice A:

Temperature is not a priority finding to report to the provider. The newborn's temperature may vary slightly depending on the environment and the method of measurement. A normal temperature range for a newborn is 36.5°C to 37.5°C (97.7°F to 99.5°F).

Choice B:

Respiratory findings are important to report to the provider because the newborn had a low Apgar score at 1 minute and required positive pressure ventilation and oxygen. The nurse should assess the newborn's respiratory rate, effort, breath sounds, and oxygen saturation. Any signs of respiratory distress, such as tachypnea, grunting, retractions, nasal flaring, or cyanosis, should be reported immediately.

Choice C:

Serum glucose is a critical finding to report to the provider because the newborn is at risk for hypoglycemia due to the abruptio placenta and the emergency cesarean birth. Hypoglycemia can cause neurological damage and seizures in newborns. A normal serum glucose level for a newborn is 40 to 60 mg/dL.

Choice D:

Hematocrit is a significant finding to report to the provider because the newborn may have polycythemia or anemia due to the abruptio placenta and the blood loss during delivery.

Polycythemia can cause hyperviscosity and thrombosis, while anemia can cause hypoxia and shock. A normal hematocrit level for a newborn is 42% to 65%.

Choice E:

White blood cell count is not a priority finding to report to the provider. The newborn's white blood cell count may be elevated due to the stress of birth or a maternal infection. A normal white blood cell count for a newborn is 9,000 to 30,000/mm3.

Choice F:

Hemoglobin is an important finding to report to the provider because the newborn may have polycythemia or anemia due to the abruptio placenta and the blood loss during delivery.

Hemoglobin is the main component of red blood cells that carries oxygen to the tissues. A normal hemoglobin level for a newborn is 14 to 24 g/dL.

Choice G:

Heart rate is a vital finding to report to the provider because the newborn had a non- reassuring fetal heart rate during labor and delivery. The nurse should monitor the newborn's heart rate and rhythm for any signs of bradycardia, tachycardia, or arrhythmias. A normal heart rate range for a newborn is 110 to 160 beats per minute.

Choice A reason:

A prior vaginal delivery is not a contraindication for VBAC. In fact, it is a positive predictor of success for VBAC, as it indicates that the woman has a proven pelvis and can tolerate labor.

Choice B reason:

The gestation of 42 weeks is not a contraindication for VBAC. However, it is associated with an increased risk of stillbirth while awaiting spontaneous labor, which should be balanced against the risks of induction of labor or elective repeat cesarean.

Choice C reason:

Maternal obesity is a relative contraindication for VBAC. It is associated with a lower success rate of VBAC, a higher risk of uterine rupture, and a higher risk of maternal and neonatal complications. The decision to attempt VBAC in obese women should be made on a case-by-case basis by a senior obstetrician.

Choice D reason:

One prior cesarean delivery is not a contraindication for VBAC. Most women who have had one prior lower segment cesarean delivery are eligible for VBAC, as the risk of uterine rupture is low (0.5%) and the success rate is high (72-75%).

Choice E reason:

A macrosomic fetus is a relative contraindication for VBAC. It is associated with a lower success rate of VBAC, a higher risk of uterine rupture, and a higher risk of shoulder dystocia and birth trauma. The decision to attempt VBAC in women with suspected macrosomia should be made on a case-by-case basis by a senior obstetrician.
