Which factor is NOT associated with greater risk for respiratory distress in newborns?

• A. Less than 30 weeks gestation
• B. Weight less than 2.5 lbs
• C. Full term birth
• D. Airway obstruction

Answer: (C)

Newborns who are born full-term (typically defined as between 37 and 42 weeks of gestation) generally have a lower risk of respiratory distress when compared to preterm infants. This is because full-term babies have had more time to develop crucial lung structures and surfactant production, which helps keep the air sacs in the lungs from collapsing. In contrast, factors such as being less than 30 weeks gestation or having a birth weight of less than 2.5 lbs are strongly linked to increased risk for respiratory complications due to immature lung development and potential issues with breathing support. Airway obstruction can also lead to respiratory distress by physically hindering the ability to breathe effectively. Therefore, the correct answer identifies a factor that does not contribute to increased risk, contrasting with the other choices that are indeed associated with a higher likelihood of respiratory distress in newborns.
