Which of the following is NOT a reason for the increased risk of complications in preterm newborns?

Development of strong respiratory muscles is not a reason for the increased risk of complications in preterm newborns. In fact, one of the significant challenges faced by preterm infants is that their respiratory muscles and the lungs themselves are often immature, which can lead to respiratory distress and difficulties with breathing.

In contrast, preterm newborns are at risk for complications primarily due to their smaller blood volumes, which can affect their ability to circulate blood effectively and maintain blood pressure. Additionally, their vulnerability to hypoglycemia is heightened because they generally have lower stores of glycogen and are less able to regulate their blood sugar levels. Immature lungs contribute significantly to complications, as preterm infants frequently experience respiratory distress syndrome (RDS) due to a lack of surfactant, which is crucial for lung function.
