Which nursing intervention would be the priority to prevent tracheal necrosis in a client with an endotracheal tube in place?

A. Maintaining adequate cuff pressure: Excessive pressure from the endotracheal tube cuff can compress tracheal mucosa, leading to ischemia and tracheal necrosis. Monitoring and maintaining the cuff at the recommended pressure (20–30 mm Hg) ensures adequate ventilation while minimizing injury to the tracheal wall, making it the priority intervention. B. Performing oral care every four hours: Regular oral care helps prevent ventilator-associated pneumonia and maintains oral hygiene, but it does not directly prevent tracheal necrosis caused by cuff pressure. C. Performing tracheostomy care every four hours: Tracheostomy care is specific to clients with a tracheostomy, not a standard endotracheal tube. While important for preventing infection, it does not address the risk of tracheal necrosis from cuff pressure. D. Administering peptic ulcer prophylaxis: Peptic ulcer prophylaxis is used to prevent stress-related mucosal damage in critically ill clients. It does not affect tracheal tissue integrity or prevent necrosis related to endotracheal tube placement.
