A 45-year-old man was a driver in a motor vehicle collision. The patient is not able to offer a medical history during initial presentation. His temperature is 97.6°F (36.4°C), blood pressure is 104/74 mmHg, pulse is 150/min, respirations are 12/min, and oxygen saturation is 98% on room air. On exam, he does not open his eyes, he withdraws to pain, and he makes incomprehensible sounds. He has obvious signs of trauma to the chest and abdomen. His abdomen is distended and markedly tender to palpation. He also has an obvious open deformity of the left femur. What is the best initial step in management?
AEmergency open fracture repair
BPacked red blood cells
CExploratory laparotomy
DIntubation
E100% oxygen
A 47-year-old man is brought to the emergency room by his wife. She states that they were having dinner at a restaurant when the patient suddenly became out of breath. His past medical history is irrelevant but has a 20-year pack smoking history. On evaluation, the patient is alert and verbally responsive but in moderate respiratory distress. His temperature is 37°C (98.6°F), blood pressure is 85/56 mm Hg, pulse is 102/min, and respirations are 20/min. His oxygen saturation is 88% on 2L nasal cannula. An oropharyngeal examination is unremarkable. The trachea is deviated to the left. Cardiopulmonary examination reveals decreased breath sounds on the right lower lung field with nondistended neck veins. Which of the following is the next best step in the management of this patient?
AUrgent needle decompression
BD-dimer levels
CNebulization with albuterol
DChest X-ray
EHeimlich maneuver
A 27-year-old man is brought to the emergency department 45 minutes after being involved in a motor vehicle collision. He is agitated. He has pain in his upper right arm, which he is cradling in his left arm. His temperature is 36.7°C (98°F), pulse is 135/min, respirations are 25/min, and blood pressure is 145/90 mm Hg. His breathing is shallow. Pulse oximetry on 100% oxygen via a non-rebreather face mask shows an oxygen saturation of 83%. He is confused and oriented only to person. Examination shows multiple bruises on the right anterior thoracic wall. The pupils are equal and reactive to light. On inspiration, his right chest wall demonstrates paradoxical inward movement while his left chest wall is expanding. There is pain to palpation and crepitus over his right anterior ribs. The remainder of the examination shows no abnormalities. An x-ray of the chest is shown. Two large-bore IVs are placed. After fluid resuscitation and analgesia, which of the following is the most appropriate next step in management?
ABedside thoracotomy
BSurgical fixation of right third to sixth ribs
CIntubation with positive pressure ventilation
DPlacement of a chest tube
ECT scan of the chest
