Which of the following specifies a risk factor linked to post-term infants?

Post-term infants, those born after 42 weeks of gestation, face various risks due to prolonged gestation and possible placental insufficiency. Among these, the risk for asphyxia is significant. This can occur because the placenta may not function effectively as it ages, leading to reduced oxygen and nutrient supply to the fetus. As a result, post-term infants may experience a drop in heart rate or signs of distress during delivery, which can lead to asphyxia.

The risk of asphyxia in post-term infants is compounded by factors such as meconium aspiration if the fetus passes meconium before or during labor, increasing the chance of respiratory complications. Therefore, identifying asphyxia as a risk factor is essential, particularly for planning appropriate monitoring and interventions during labor and delivery.

While increased jaundice risk, higher likelihood of anemia, and frequent hypoglycemia are also concerns typically associated with infants, they are not as directly linked to the specific conditions and physiological changes observed in post-term infants as asphyxia is.
