2How many types of pneumothorax are there?
- Atwo
- Bthree
- Cfour
- Dfive
3What is the initial management of an open pneumothorax?
- Ano emergency treatment is needed
- Bsuture of the wound
- Cpromptly closing the defect with a sterile occlusive dressing
- Demergency thoracotomy
4Which of these statements is true for the tension pneumothorax?
- Awe should wait for the chest x-ray to confirm the diagnosis before proceeding with the treatment
- Bthe mediastinum is shifted to the opposite side, decreasing the venous return and compressing the opposite lung
- Cit results from large defects. of the chest wall that remain open
- Dthe treatment is emergency thoracotomy
- Eall of the above
5What other condition can be initially confused with tension pneurnothorax?
- Aflail chest
- Bopen pneumothorax
- Cmyocardial infarction
- Dcardiac tamponade
6A teenage boy falls from his bicycle and is run over by a truck. On arrival in the emergency room, he is awake and alert and appears frightened but in no distress. The chest radiograph suggests an air-fluid level in the left lower lung field and the nasogastric tube seems to coil upward into the left chest. The next best step in management is
- APlacement of a left chest tube
- BImmediate thoracotomy
- CImmediate celiotomy
- DEsophagogastroscopy
- ERemoval and replacement of the nasogastric tube; diagnostic peritoneal lavage
7A 25-year-old woman arrives in the emergency room following an automobile accident. She is acutely dyspneic with a respiratory rate of 60 breaths/min. Breath sounds. are markedly diminished on the right side. The first step in managing the patient should be to
- ATake a chest x-ray
- BDraw arterial blood for blood gas determination
- CDecompress the right pleural space
- DPerform pericardiocentesis
- EAdminister intravenous fluids
8A 25-year-old woman arrives in the emergency room following an automobile accident. She is acutely dyspneic with a respiratory rate of 60 breaths/min. Breath sounds. are markedly diminished on the right side.
A chest x-ray of this woman before therapy would probably reveal- AAir in the right pleural space
- BShifting of the mediastinum toward the right
- CShifting of the trachea toward the right
- DDilation of the intrathoracic vena cava
- EHyperinflation of the left lung
9A 23-year-old previously healthy man presents to the emergency room after sustaining a single gunshot wound to the left chest. The entrance wound is 3 cm inferior to the nipple and the exit wound is just below the scapula. A chest tube is placed that drains 400 mL of blood and continues to drain 50-75 mtL/h during the initial resuscitation. Initial blood pressure of 70/0 mm Hg responds to 2 L crystalloid and is now 100/70 mm Hg. Abdominal examination is “unremarkable. Chest x-ray reveals a reexpanded lung and no free air under the diaphragm. The next management step should be
- Aadmission and observation
- Bperitoneal lavage
- Cexploratory thoracotomy
- Dexploratory celiotomy
- Elocal wound exploration
10Regarding myocardial contusion from blunt chest trauma, which of the following statements is correct?
- AElevated cardiac isoenzyme levels sensitively identify patients at risk for life-threatening arrhythmias
- BThe majority of patients have abnormalities on the initial ECG post injury
- CFirst-pass radionuclide angiography (RNA) and echocardiography are considered the “gold standard” for diagnosis
- DRNA and echocardiography are good predictors of subsequent Cardiac complications such as arrhythmias and pump failure
- EAll patients diagnosed with myocardial contusion should be monitored in an intensive care unit setting for 72 h
11Which of the following situations would be an indication for performance of a thoracotomy in the emergency room?
- AMassive hemotharax following blunt trauma to the chest
- BBlunt trauma ‘to multiple organ systems with obtainable vita! signs in the field but none on arrival in the emergency roam
- CRapidly deteriorating patient with cardiac tamponade from penetrating thoracic trauma
- DPenetrating thoracic trauma and no signs of life in the field
- EPenetrating abdominal trauma and no signs of life in the field
12How do we define a massive hemothorax?
- Aaccumulation of more than 300 ml of blood
- Baccumulation of more than 1000 ml of blood
- Caccumulation of more than 1500 ml of blood
- Daccumulation of more than 2500 ml of blood
13What is the initial treatment of hemothorax?
- Aa rapid crystalloid infusion
- Binsertion of a chest tube
- Cblood transfusions as soon as possible
- Dall of the above
14What is the definition of flail chest?
- Amultiple rib fractures in one fracture line
- Baccumulation of more than 1500 ml of blood in the thoracic cavity
- Cmultiple rib fractures - three or more ribs fractured in two or more places
- Done rib fractured in two fracture lines
15What causes the. greatest physiologic insult in patients with flail chest?
- Athe multiple rib fractures
- Bthe abnormal chest wall movement
- Cthe massive blood loss
- Dthe pulmonary contusion
16What is the mast important part in the treatment of patients with pulmonary contusion?
- Aemergency thoracotomy
- Btreatment of posttraumatic lung infection
- Cobservation and follow-up
- Dblood transfusions
- Eall of the above
