Final answer:
Thermal burns to the airway require immediate intubation and airway management.
Step-by-step explanation:
In the case of thermal burns to the patient's airway, the appropriate action would be immediate intubation and airway management. This is important because thermal burns to the airway can cause swelling and difficulty breathing, which can quickly become life-threatening. Intubation and airway management involves inserting a tube into the patient's airway to maintain an open and secure passage for breathing.
