What is a sign that a newborn may be at risk for meconium aspiration syndrome?
Asymmetrical breathing
Born before 38 weeks gestation
Yellow-green staining on the umbilical cord
Acrocyanosis
The Correct Answer is C
Choice A reason:
Asymmetrical breathing is not a sign of meconium aspiration syndrome (MAS). It is a sign of diaphragmatic hernia, a condition where the abdominal organs push into the chest cavity and interfere with lung development.
Choice B reason:
Born before 38 weeks gestation is not a sign of MAS. It is a risk factor for respiratory distress syndrome (RDS), a condition where the lungs are not fully developed and lack surfactant, a substance that helps keep the air sacs open.
Choice C reason:
Yellow-green staining on the umbilical cord is a sign of MAS. It indicates that the baby has passed meconium into the amniotic fluid before or during birth and may have inhaled it into the lungs. Meconium is a sticky substance that becomes the baby's first poop. It can block or irritate the airways, damage lung tissue and prevent oxygen exchange.
Choice D reason:
Acrocyanosis is not a sign of MAS. It is a normal finding in newborns where the hands and feet appear bluish due to immature circulation. It usually resolves within 24 to 48 hours after birth.

Correct Answer is C
Explanation
Choice A reason:
Tremors are not a sign of hyperbilirubinemia, but they may indicate other problems such as hypoglycemia, hypocalcemia, or seizures. Tremors are involuntary muscle movements that can affect different parts of the body.
Choice B reason:
Newborn rash, also known as erythema toxicum, is a common and harmless skin condition that affects many newborns. It causes red spots with white or yellow centers on the face, chest, back, or limbs. It is not related to hyperbilirubinemia or liver function.
Choice C reason:
Cephalohematoma is a collection of blood under the scalp that occurs due to trauma during delivery. It can increase the risk of hyperbilirubinemia because the breakdown of red blood cells in the hematoma releases bilirubin into the bloodstream. Bilirubin is a yellow pigment that is normally processed by the liver and excreted in stool and urine. If the liver is overwhelmed by the amount of bilirubin, it can cause jaundice, which is yellowing of the skin and eyes.
Choice D reason:
Acrocyanosis is a bluish discoloration of the hands and feet that occurs in some newborns due to poor circulation. It is usually a normal and transient phenomenon that does not indicate any serious problem. It is not a sign of hyperbilirubinemia or liver dysfunction.
Correct Answer is ["A","B","E"]
Explanation
Choice A:
Tremors. This is a sign of hypoglycemia in a newborn because low blood sugar can cause shakiness or jitteriness in the muscles. •
Choice B:
Lethargy. This is a sign of hypoglycemia in a newborn because low blood sugar can cause low energy, poor feeding, or lack of interest in eating.
Choice C:
Hunger. This is not a sign of hypoglycemia in a newborn because low blood sugar can actually reduce the appetite or cause feeding difficulties.
Choice D:
Jaundice. This is not a sign of hypoglycemia in a newborn because jaundice is caused by high levels of bilirubin in the blood, not low levels of glucose.
Choice E:
Weak cry. This is a sign of hypoglycemia in a newborn because low blood sugar can affect the vocal cords and the respiratory system, causing a weak or high-pitched cry.
