Premature newborn grunting respirations are most likely an attempt to do which of the following?

Explanation:
Premature newborn grunting respirations are a mechanism to keep the alveoli inflated and improve gas exchange. Grunting involves partially closing the glottis during exhalation, which creates a little back pressure that acts like positive end-expiratory pressure (PEEP). In premature infants, surfactant deficiency makes alveoli prone to collapse at the end of expiration, so maintaining alveolar inflation helps keep the small air sacs open and enhances oxygenation. It’s not primarily about removing fluid, trapping carbon dioxide, or clearing mucus, but about preventing alveolar collapse to improve breathing.
