Write answer in between .Q:A 28-year-old soldier is brought back to a military treatment facility 45 minutes after sustaining injuries in a building fire from a mortar attack. He was trapped inside the building for around 20 minutes. On arrival, he is confused and appears uncomfortable. He has a Glasgow Coma Score of 13. His pulse is 113min, respirations are 18min, and blood pressure is 10870 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 96. Examination shows multiple second-degree burns over the chest and bilateral upper extremities and third-degree burns over the face. There are black sediments seen within the nose and mouth. The lungs are clear to auscultation. Cardiac examination shows no abnormalities. The abdomen is soft and nontender. Intravenous fluid resuscitation is begun. Which of the following is the most appropriate next step in management?? A: Insertion of nasogastric tube and enteral nutrition, B: Intravenous antibiotic therapy, C: Intubation and mechanical ventilation, D: Intravenous corticosteroid therapy, E: Immediate bronchoscopy,  <response>: This is a question about the initial management of a 28-year-old soldier with burn injuries and smoke inhalation from a building fire caused by a mortar attack. The key findings are that he has second and third degree burns, is confused with a GCS of 13, has black sediments in his nose and mouth indicating smoke inhalation injury, and is tachycardic and hypotensive indicating potential shock. The main considerations are airway management, assessing inhalation injury, fluid resuscitation for shock, pain control, and preventing infection. Of the answer choices, intubation and mechanical ventilation is most appropriate as the patient likely has significant airway burns and inhalation injury that can quickly progress to respiratory failure. Nasogastric tube and antibiotics are not immediately necessary. Corticosteroids are not routinely indicated. Bronchoscopy can wait until the patient is stabilized.C: Intubation and mechanical ventilation
