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

Choice A:

Two arteries and two veins. This is incorrect because the umbilical cord normally has only three blood vessels: one vein and two arteries. Having four blood vessels is a rare anomaly that can be associated with congenital defects. •

Choice B:

Two veins and one artery. This is incorrect because the umbilical cord normally has only one vein and two arteries. Having two veins and one artery is another rare anomaly that can also be associated with congenital defects. •

Choice C:

One artery and one vein. This is incorrect because the umbilical cord normally has two arteries and one vein. Having only one artery and one vein is a common anomaly that occurs in about 1% of singleton pregnancies and 5% of twin pregnancies. It can be associated with intrauterine growth restriction, congenital anomalies, and perinatal mortality. •

Choice D:

Two arteries and one vein. This is correct because the umbilical cord normally has two arteries and one vein. The vein carries oxygenated blood from the placenta to the fetus, while the arteries carry deoxygenated blood from the fetus to the placenta. The umbilical cord also contains Wharton's jelly, which is a gelatinous substance that protects the blood vessels from compression.

Choice A reason:

Blood pressure is not a priority finding for a newborn with neonatal abstinence syndrome (NAS). Blood pressure is usually normal or slightly elevated in NAS, and it is not a reliable indicator of the severity of withdrawal symptoms.

Choice B reason:

Gastrointestinal disturbances are a common and serious finding for a newborn with NAS. Vomiting and diarrhea can lead to dehydration, electrolyte imbalance, and poor weight gain. Projectile vomiting can also increase the risk of aspiration. This finding requires immediate follow-up and intervention.

Choice C reason:

Skin color is not a priority finding for a newborn with NAS. Acrocyanosis (bluish color of the hands and feet) is a normal finding in newborns and does not indicate hypoxia or poor circulation. It usually resolves within the first few days of life.

Choice D reason:

NAS score is not a priority finding for a newborn with NAS. NAS score is a tool used to assess the severity of withdrawal symptoms and the need for pharmacological treatment. It is based on a set of clinical signs and symptoms that are scored at regular intervals. However, it is not a substitute for clinical judgment and individualized care. The NAS score alone does not determine the urgency of follow-up.

Choice E reason:

Temperature is not a priority finding for a newborn with NAS. The temperature may be slightly elevated or normal in NAS, and it is not a specific sign of infection or withdrawal. Temperature regulation is important for newborns, but it is not an immediate concern in this case.

Choice F reason:

Oxygen saturation is a priority finding for a newborn with NAS. Tachypnea (rapid breathing) and retractions (inward movement of the chest wall) are signs of respiratory distress, which can compromise oxygen delivery to the tissues and organs. Hypoxia (low oxygen level) can cause brain damage, organ failure, and death if not corrected promptly. This finding requires immediate follow-up and intervention.

Choice G reason:

Central nervous system disturbances are a priority finding for a newborn with NAS. Increased muscle tone, tremors, high-pitched cries, and seizures are signs of neurological dysfunction, which can indicate brain injury, bleeding, or infection. Seizures can also worsen hypoxia and metabolic acidosis. This finding requires immediate follow-up and intervention.

Choice H reason:

Respiratory rate is not a priority finding for a newborn with NAS. Respiratory rate may be increased or normal in NAS, and it is not a specific sign of respiratory distress or infection. Respiratory rate should be monitored along with other vital signs, but.
