A 30 year old male is brought to the hospital after falling 6 meters (20 feet). Inspection reveals an obvious flail chest on the right. The patient is tachypneic. Breath sounds are present and symmetrical. There is no significant hyperresonance or dullness. Arterial blood gases obtained while the patient receives oxygen by face mask are: Pao2 of 45 mm Hg (6 kPa), PaCO2 of 28 mm Hg (3.7 kPa), and pH of 7.47. The component of injury that is most likely responsible for the abnormalities in the patient's blood gases is: a) hypoventilation. b)hypovolemia c) small pneumothorax. d)pulmonary contusion. - ANSWER>>d) pulmonary contusion. Which one of the following statements concerning massive hemothorax is TRUE? a) It is usually caused by blunt thoracic trauma. b) It is commonly confused with a pneumothorax. c) The diagnosis should be confirmed by upright, plain chest roentgenograms prior to treatment. d)The condition should be suspected in situations associated with shock and unilateral absent breath sounds. - ANSWER>>d) The condition should be suspected in situations associated with shock and unilateral absent breath sounds. A 25-year-old man is brought to the hospital after being involved in a motor vehicular crash when his car struck a bridge abutment. He is intoxicated, has a Glasgow Coma Scale score of 13, and complains of abdominal pain. His blood pressure was 80 mm Hg systolic by palpation on admission to the hospital, but it rapidly increased to 110/70 with the administration of intravenous fluids. His heart rate is now 120 beats per minute. The chest roentgenogram shows loss of the aortic knob, widening of the mediastinum, no rib fractures, and no hemopneumothorax. Contrast CT angiography: a) is not indicated. b)should be performed after tube thoracostomy. c) is not necessary if non-contrast CT scan of the chest is normal. d)should be performed after a FAST scan. - ANSWER>>d) should be performed after a FAST scan.
