Which one of the following statements is TRUE? a. Vasoactive medications have no role in this patient's management. b. The hypotension should be managed with volume resuscitation alone. c. Flexion and extension views of the c­spine should be performed early. d. Occult abdominal visceral injuries can be excluded as a cause of hypotension. e. Flaccidity of the lower extremities and loss of deep tendon reflexes are expected. 6. The following are contraindications for tetanus toxoid administration: a. History of neurological reaction or severe hypersensitivity to the product. b. Local side effects. c. Muscular spasms. d. Pregnancy. e. All of the above. 7. After being involved in a motor vehicle crash, a 25­year­old man is brought to a hospital with a general surgeon on duty. He has a GCS of 13 and complains of abdominal pain.

His heart rate remains 120 beats per minute. Computed tomography shows an aortic injury and splenic laceration with free abdominal fluid. His blood pressure falls to 70 mm Hg after CT. The next step is: a. contrast angiography. b. transfer to a higher level trauma center. c. exploratory laparotomy. d. transfuse packed red blood cells. e. transesophageal echocardiography. 8. Which one of the following statements regarding abdominal trauma in the pregnant patient is TRUE? a. The fetus is in jeopardy only with major abdominal trauma. b. Leakage of amniotic fluid is an indication for hospital admission. c. Indications for peritoneal lavage are different from those in the nonpregnant patient. d.

Administering thrombolytic therapy. d. Perform right lower extremity fasciotomy. e. Immediately transferring the patient to a trauma center.
