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.

Explanation
Choice A reason:
Moro is a newborn reflex that occurs when the baby is startled by a loud sound or movement. The baby will cry, throw back his or her head, and then pull his or her limbs into the body. This reflex lasts until the baby is about 2 months old.
Choice B reason:
Rooting is a newborn reflex that starts when the corner of the baby's mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.
Choice C reason:
Gag is a newborn reflex that prevents the baby from choking on foreign objects. The baby will cough, gag or spit out anything that touches the back of the throat or the roof of the mouth. This reflex is present throughout life.
Choice D reason:
Running is not a newborn reflex. It is a voluntary movement that develops later in childhood. Choice E reason:
Babinski is a newborn reflex that occurs when the sole of the foot is stroked from heel to toe. The baby will fan out and curl up the toes and twist the foot inward. This reflex lasts until the baby is about 12 months old.
Choice F reason:
Stepping is a newborn reflex that occurs when the baby is held upright with his or her feet touching a solid surface. The baby will appear to take steps or dance. This reflex lasts about 2 months.
Choice G reason:
The crawling reflex is a developmental milestone observed in infants around 6-8 months of age. It involves the baby moving on their hands and knees, often starting with a belly-crawling motion. Unlike newborn reflexes, this skill is learned and requires muscle coordination and strength.
Choice H reason:
Standing with support is a developmental milestone typically achieved by infants around 9-12 months. In this skill, the baby pulls themselves up to a standing position while holding onto furniture or a caregiver’s hands. It is a learned behavior reflecting increased muscle strength and balance, distinct from newborn reflexes.
Choice I reason:
The pincer grasp is a fine motor skill that usually develops between 8-12 months. It involves the baby using the thumb and index finger to pick up small objects. This ability is not a reflex but a learned skill that demonstrates improved hand-eye coordination and dexterity.
Correct Answer is D
Explanation
Choice A reason:
Injury sustained to the perineum during birth is not a perinatal injury, but a perineal injury. The perineum is the area between the anus and the genitals, and it can be torn or cut during vaginal delivery. This is a common complication that affects the mother, not the fetus or newborn.
Choice B reason:
Traumatic injury to the mother during pregnancy is not a perinatal injury, but a maternal injury. This can occur due to accidents, violence, or complications of pregnancy such as preeclampsia or placental abruption. This can affect the mother's health and well-being, and may also have consequences for the fetus or newborn.
Choice C reason:
Traumatic injury to a fetus is not a perinatal injury, but a fetal injury. This can occur due to external forces such as blunt trauma, penetrating trauma, or radiation exposure that affect the fetus in utero. This can cause fetal distress, bleeding, fractures, or organ damage.
Choice D reason:
Injury sustained surrounding birth is a perinatal injury. This occurs in the period shortly before, during, or after delivery. This can be a critical time when the baby has to transition from surviving off oxygen, blood, and nutrients from the mother to separating from the womb and breathing oxygen from the air. Perinatal injuries can include head injuries, nerve injuries, hemorrhages, fractures, or soft-tissue injuries that result from the forces of labor and delivery or medical interventions such as forceps or vacuum extraction. Perinatal injuries can lead to long-term neurodevelopmental challenges for the newborn.
