NCC Maternal Newborn Nursing Practice Exam

When a preterm infant presents with rapid breathing and cyanosis, respiratory distress syndrome (RDS) is a likely condition due to its common occurrence in this vulnerable population. RDS is primarily caused by inadequate surfactant production in the lungs, which is crucial for keeping the alveoli open and facilitating gas exchange. Preterm infants, especially those born before 34 weeks of gestation, are at a higher risk for developing this condition. In cases of RDS, the infant might show signs such as increased respiratory effort, grunting, nasal flaring, and retractions, alongside cyanosis, indicating insufficient oxygenation of the blood. This condition typically arises shortly after birth and requires prompt medical intervention, including the administration of oxygen therapy and surfactant replacement. Understanding RDS's specific clinical manifestation in preterm infants helps distinguish it from other conditions such as infection or congenital heart defects, which can also present with respiratory symptoms but have different underlying mechanisms and onset characteristics. Hypoglycemia, while concerning in preterm infants, presents with different signs such as jitteriness or lethargy rather than respiratory distress.
