The secretion of surfactant into alveolar mucus occurs late in fetal development. So, babies who are born prematurely may not have adequate levels of surfactant secretion, leading to a condition known as neonatal respiratory distress syndrome. Which one of the following would you most expect in this baby? A. systemic arterial PO2 of 100 mm HgB. hyperinflated lungsC. collapse of small alveoliD. slow breathing rateE. low PCO2 in systemic arterial blood

Paige Rosales · Answer 1

C. collapse of small alveoli

Explanation:

Neonatal Respiratory Distress Syndrome happens in premature babies when there is no sufficient surfactant in the lungs. A premature baby may not have made sufficient surfactant yet. Because of this, the small alveoli collapse whenever the baby tries to breathe.
