A nurse has admitted a client with burns to the head, face, and hands. On initial assessment, wheezing is noted. On reassessment, the nurse notes decreased bilateral lung sounds. The client appears anxious, respiration rate is 30, and Pulse oximetry is 80%. Which of the following is the priority action the nurse should take?

A. Document the change and continue to monitor the client's respiratory rate: While documentation is important, delaying action in the presence of rapid deterioration in airway status can be life-threatening. This option does not address the urgency of the situation. B. Encourage the client to cough and auscultate the lungs again: Coughing may be beneficial in clearing secretions, but the combination of facial burns, declining breath sounds, and low oxygen saturation indicates airway edema, not mucus obstruction. C. Reposition the client in high-Fowler's position and reassess breath sounds: Elevating the head may ease breathing slightly, but it does not resolve the risk of impending airway closure. Airway management takes priority over repositioning. D. Notify the healthcare provider and prepare for endotracheal intubation: Facial burns and decreased breath sounds suggest progressive airway edema, and intubation must be initiated before the airway becomes inaccessible. Prompt action is critical to preserve oxygenation and prevent respiratory arrest.
