The nurse places an infant with a tracheoesophageal fistula under a radiant warmer with the infant's head elevated at a 45-degree angle.Which statement by the mother indicates an understanding of the most important reason for this position?

Choice A rationaleElevating the head reduces the risk of aspiration by preventing stomach contents, including gastric juices, from entering the lungs. This position is essential for infants with tracheoesophageal fistula due to the abnormal connection between the trachea and esophagus, which increases aspiration risk.Choice B rationaleFacilitating food digestion is not the primary goal of this positioning. Gastric motility and digestion are unaffected by head elevation, making this rationale irrelevant to the question. Therefore, this is not the correct choice.Choice C rationaleWhile head elevation can improve breathing by reducing diaphragm compression, the primary purpose in this context is to prevent aspiration. Lung expansion is a secondary benefit, but it is not the main reason for this position.Choice D rationaleReducing stomach pressure is not the key reason for elevating the head in this case. Although head elevation can minimize intra-abdominal pressure, this rationale does not address the critical concern of preventing aspiration in tracheoesophageal fistula. .
