A 32-year-old man is brought to the emergency department 15 minutes after falling 7 feet onto a flat-top wooden post. On arrival, he is in severe pain and breathing rapidly. His pulse is 135/min, respirations are 30/min, and blood pressure is 80/40 mm Hg. There is an impact wound in the left fourth intercostal space at the midaxillary line. Auscultation shows tracheal deviation to the right and absent breath sounds over the left lung. There is dullness to percussion over the left chest. Neck veins are flat. Cardiac examination shows no abnormalities. Two large-bore intravenous catheters are placed and intravenous fluid resuscitation is begun. Which of the following is the most likely diagnosis?
ABronchial rupture
BCardiac tamponade
CFlail chest
DHemothorax
ETension pneumothorax
A 27-year-old man presents to the emergency department with severe dyspnea and sharp chest pain that suddenly started an hour ago after he finished exercising. He has a history of asthma as a child, and he achieves good control of his acute attacks with Ventolin. On examination, his right lung field is hyperresonant along with diminished lung sounds. Chest wall motion during respiration is asymmetrical. His blood pressure is 105/67 mm Hg, respirations are 22/min, pulse is 78/min, and temperature is 36.7°C (98.0°F). The patient is supported with oxygen, given corticosteroids, and has had analgesic medications via a nebulizer. Considering the likely condition affecting this patient, what is the best step in management?
ACT scan
BABG
CChest X-rays
DTube insertion
ESonogram
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
