1. The primary indication for transferring a patient to a higher level trauma center is: unavailability of a surgeon or operating room staff. multiple system injuries, including severe head injury. resource limitations as determined by the transferring doctor. resource limitations as determined by the hospital administration. widened mediastinum on chest x-ray following blunt thoracic trauma.
2. Which one of the following statements regarding patients with thoracic spine injuries is TRUE? Log-rolling may be destabilizing to fractures from T- 12 to L-1. Adequate immobilization can be accomplished with the scoop stretcher. Spinal cord injury below T- 10 usually spares bowel and bladder function. Hyperflexion fractures in the upper thoracic spine are inherently unstable. These patients rarely present with spinal shock in association with cord injury.
3. teen-aged bicycle rider is hit by a truck traveling at a high rate of speed. In the emergency department, she is actively bleeding from open fractures of her legs, and has abrasions on her chest and abdominal wall. Her blood pressure is 80/ mm Hg, heart rate is 140 beats per minute, respiratory rate is 8 breaths per minute, and GCS score is 6. The first step in managing this patient is to: obtain a lateral cervical spine x-ray. insert a central venous pressure line. administer 2 liters of crystalloid solution. perform endotracheal intubation and ventilation. apply the PASG and inflate the leg compartments.
4. Contraindication to nasogastric intubation is the presence of a: gastric perforation. diaphragmatic rupture. open depressed skull fracture. fracture of the cervical spine. fracture of the cribriform plate.
5. young man sustains a ritle wound to the mid- abdomen. He is brought promptly to the emergency department by prehospital personnel. His skin is cool and diaphoretic, and his systolic blood pressure is 58 rnm Hg. Warmed crystalloid fluids are initiated without improvement in his vital signs. The next, most appropriate step is to perform: a celiotomy. an abdominal CT scan. diagnostic laparoscopy. abdominal ultrasonography. a diagnostic peritoneal lavage.
6. young woman sustains a severe head injury as the result of a motor vehicular crash. In the emergency department, her GCS score is 6. Her blood pressure is 140/90 mm Hg and her heart rate is 80 beats per minute. She is intubated and is being mechanically ventilated. Her pupils are 3 mm in size and equally reactive to light. There is no other apparent injury. The most important principle to follow in the early management of her head injury is to: administer an osmotic diuretic. prevent secondary brain injury.

Intraabdominal visceral injuries are unlikely. The patient probably has an acute epidural hematoma.

12. crosstable, lateral x-ray of the cervical spine: must precede endotracheal intubation. excludes serious cervical spine injury. is an essential part of the primary survey. is not necessary for unconscious patients with penetrating cervical injuries. is unacceptable unless 7 cervical vertebrae and the C- 7 to T- 1 relationship are visualized.
13. During resuscitation, which one of the following is the most reliable as a guide to volume replacement? Pulse rate Hematocrit Blood pressure Urinary output Jugular venous pressure defmitive treatment in managing this patient is to: administer 0-negative blood. apply extemal warming devices. control internal hemorrhage operatively. apply the pneumatic antishock garment. infuse large volumes of intravenous crystalloid solution.
14. To establish a diagnosis of shock: systolic blood pressure must be below 90 mm Hg. the presence of a closed head injury should be excluded. acidosis should be present by arterial blood \gas analysis. the patient must fail to respond to intravenous fluid infu.sion. clinical evidence of inadequate organ perfusion must be present.
15. Absence of breath sounds and dullness to percussion over the left hemithorax are fmdings best explained by:
16. Which one of the following is the recommended method for initially treating frostbite? Vasodilators Anticoagulants Warm (40°C) water Padding and elevation Topical application of silvasulphadiazine
17. young man sustains a gunshot wound to the abdomen and is brought promptly to the emergency department by prehospital personnel. His skin is cool and diaphoretic, and he is confused. His pulse is thready and his femoral pulse is only weakly palpable. The left hemothorax. cardiac contusion. left simple pneumothorax. left diaphragmatic rupture. right tension pneumothorax.
18. 17 - year-old helmeted motorcyclist is struck broadside by an automobile at an intersection. He is unconscious at the scene with a blood pressure of 140/90 mm Hg, heart rate of 90 beats per minute, and respiratory rate of 22 breaths per minute. His respirations are sonorous and deep. His GCS score is 6. Immobilization of the entire patient may include the use of all the following EXCEPT: air splints.

bolstering devices. a long spine board. a scoop-style stretcher. a semirigid cervical collar.

19. During an altercation, a 32 - year-old man sustains a gunshot wound to the right upper hemithorax, above the nipple line with an exit wound posteriorly above the scapula on the right. He is transported by ambulance to a community hospital. He is endotracheally intubated, closed tube thoracostomy is performed, and 2 liters of Ringer's lactate solution are infused through 2 large-caliber IVs. His blood pressure now is 60/0 mm Hg, heart rate is 160 beats per minute, and respiratory rate is 14 breaths per minute (ventilated with 100% 02). The most appropriate next step in managing this patient is: celiotomy. diagnostic peritoneal lavage. arterial blood gas determination. administer packed red blood cells. chest x-ray to confinn tube placement.
20. Which of the following statements regarding iWhich of the following statements regardingnjury to the central nervous system in children is TRUE? Children suffer spinal cord injury without x-ray abnormality more commonly than adults. An infant with a traumatic brain injury may become hypotensive from cerebral edema. Initial therapy for the child with traumatic brain injury includes the administration of methylprednisolone intravenously. Children have more focal mass lesions as a result of traumatic brain injury when compared to adults. Young children are less tolerant of expanding intracranial mass lesions than adults.
21. 5 - year-old boy is struck by an automobile and brought to the emergency department. He is lethargic, but withdraws purposefully from painful stimuli. His blood pressure is 90 mm Hg systolic, heart rate is 140 beats per minute, and his respiratory rate is 36 breaths per minute. The preferred route of venous access in this patient is: percutaneous femoral vein cannulation cutdown on the saphenous vein at the ankle. intraosseous catheter placement in the proximal tibia. percutaneous peripheral veins in the upper extremities. central venous access via the subclavian or interna1 jugular vein.
22. The response to catecholamines in an injured, hypovolemic pregnant woman can be expected to result in: placental abruption. fetal hypoxia and distress. fetal/maternal dysrhythmia. improved uterine blood flow. increased maternal renal blood flow.
23. Cardiac tamponade after trauma: is seldom life-threatening. can be excluded by an upright, AP chest x- ray. can be confused with a tension pneumothorax. causes a fall in systolic pressure of > 15 mm Hg with expiration. most commonly occurs after blunt injury to the anterior chest wall.

produce the greatest number of survivors based on available resources.

29. Which one of the following statements is FALSE concerning Rh isoimmunization in the pregnant trauma patient? It occurs in blunt or penetrating abdominal trauma. Minor degrees of fetomaternal hemorrhage produce it. A negative Kleihauer-Betke test excludes Rh isoimmunization. This is not a problem in the traumatized Rh-positive pregnant patient. Initiation of Rh immunoglobulin therapy does not require proof of fetomaternal hemorrhage.
30. 24 - year-old woman passenger in an automobile strikes the wind screen with her face during a head-on collision. In the emergency department, she is talking and has marked facial edema and crepitus. The highest priority should be given to: lateral, c-spine x-ray. upper airway protection. carotid pulse assessment. management of blood loss. determination of associated Injuries.
31. Early central venous pressure monitoring during fluid resuscitation in the emergency department has the greatest utility in a: patient with a splenic laceration. patient with an inhalation injury. 6 - year-old child with a pelvic fracture. patient with a severe cardiac contusion. 24 - year-old man with a massive hemothorax.
32. 32 - year-old man is brought to the hospital unconscious with severe facial injuries and noisy respirations after an automobile collision. In the emergency department, he has no apparent injury to the anterior aspect of his neck. He suddenly becomes apneic, and attempted ventilation with a face mask is unsuccessful. Examination of his mouth reveals a large hematoma of the pharynx with loss of normal anatomic landmarks. Initial management of his airway should consist of: inserting an oropharyngeal airvvay. inserting a nasopharyngeal airway. performing a surgical cricothyroidotomy. performing fiberoptic-guided nasotracheal intubation. performing orotracheal intubation after obtaining a lateral c-spine x-ray.
33. 42 - year-old man, injured in a motor vehicle crash, suffers a closed head injury, multiple palpable left rib fractures, and bilateral femur fractures. He is intubated orotracheally without difficulty. Initially, his ventilations are easily assisted with a bag¬valve device. It becomes more difficult to ventilate the patient over the next 5 minutes, and his hemoglobin oxygen saturation level decreases from 98% to89 %. The most appropriate next step is to: obtain a chest x-ray. decrease the tidal volume. auscultate the patient's chest. increase the rate of assisted ventilations. perform needle decompression of the left chest.
34. 42 - year-old man is trapped from the waist down beneath his overtumed tractor for several hours before medical assistance arrives. He is awake and alert until just before arriving in the emergency department. He is now unconscious

and responds only to painful stimuli by moaning. His pupils are 3 mm in diameter and symmetrically reactive to light. Prehospital personnel indicate that they have not seen the patient move either of his lower extremities. On examination in the emergency department, no movement of his lower extremities is detected, even in response to painful stimuli. The most likely cause for this fmding is: an epidural hematoma. a pelvic fracture. central cord syndrome. intracerebral hemorrhage. bilateral compartment syndrome.

37. Regarding shock in the child, which of the following is FALSE? Vital signs are age-related. Children have greater physiologic reserves than do adults. Tachycardia is the primary physiologic response to hypovolemia. The absolute volume of blood loss required to produce shock is the same as in adults. An initial fluid bolus for resuscitation should approximate 20 mL/kg of Ringer's lactate.
38. An electrician is electrocuted by a downed power line after a thunderstorm. He apparently made contact with the wire at the level of the right mid thigh. In the emergency department, his vital signs are normal and no dysrhythmia is noted on ECG. On examination, there is an exit wound on the bottom of the right foot.
