Select one of the following:

we should wait for the chest x-ray to confirm the diagnosis before proceeding with the treatment

A 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

Select one of the following:

Placement of a left chest tube
Immediate thoracotomy
Immediate celiotomy
Esophagogastroscopy
Removal and replacement of the nasogastric tube; diagnostic peritoneal lavage

Explanation

Question 7 of 16

A 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

Select one of the following:

Take a chest x-ray

A 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

Select one of the following:

Air in the right pleural space
Shifting of the mediastinum toward the right
Shifting of the trachea toward the right

Explanation

Question 9 of 16

1

A 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

Select one of the following:

admission and observation
peritoneal lavage
exploratory thoracotomy
exploratory celiotomy
local wound exploration

Explanation

Question 10 of 16

1

Regarding myocardial contusion from blunt chest trauma, which of the following statements is correct?

Select one of the following:

Elevated cardiac isoenzyme levels sensitively identify patients at risk for life-threatening arrhythmias
The majority of patients have abnormalities on the initial ECG post injury
First-pass radionuclide angiography (RNA) and echocardiography are considered the “gold standard” for diagnosis
RNA and echocardiography are good predictors of subsequent Cardiac complications such as arrhythmias and pump failure
All patients diagnosed with myocardial contusion should be monitored in an intensive care unit setting for 72 h

Explanation

Question 11 of 16

1

Which of the following situations would be an indication for performance of a thoracotomy in the emergency room?

Select one of the following:

Massive hemotharax following blunt trauma to the chest
Blunt trauma ‘to multiple organ systems with obtainable vita! signs in the field but none on arrival in the emergency roam
Rapidly deteriorating patient with cardiac tamponade from penetrating thoracic trauma
Penetrating thoracic trauma and no signs of life in the field
Penetrating abdominal trauma and no signs of life in the field

Explanation

Select one of the following:
