An arterial blood gas would demonstrate a base deficit between-6 and -10 mEq/L e. His systolic blood pressure will be maintained with an elevated diastolic pressure. 6. The physiological hypervalemia of pregnancy has clinical significance in the management of the severely injured, gravid woman by: a. reducing the need for blood transfusion. b. resulting in an elevated hematocrit. c. complicating the management of closed head injury. d. reducing the volume of crystalloid required for resuscitation. e. increasing the volume of blood loss to produce maternal hypotension. 7.

11. After being involved in a motor vehicle crash, a 25-year-old man is brought to a hospital that has surgery capabilities available. CT of the chest and abdomen shows an aortic injury and splenic laceration with free abdominal fluid. His blood pressure fails to 70 mm Hg after CT. The next step is to: a. obtain contrast angiography. b. transfer him to a higher-level trauma center. c. perform an exploratory laparotomy d. infuse additional crystalloid fluids. e. obtain transesophageal echocardiography. 12. Which statement 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. With penetrating trauma, injury to the mother's abdominal hollow viscus is more common in late than in early pregnancy. e. The secondary survey follows a different pattern from that of the nonpregnant patient. 13. The first maneuver to improve oxygenation after chest injury is: a. intubate the patient. b. assess arterial blood gases, c. administer supplemental oxygen. d. ascertain the need for a chest tube. e. obtain a chest x-ray. 14. A 25-year-old man, injured in a motor vehicle crash, is admitted to the ED. His pupils react sluggishly and his eyes open to pressure. He does not follow commands, but he does moan periodically. His right arm is deformed and does not respond to pressure, however, his left hand reaches purposefully toward the stimulus. Both legs are stiffly extended. His GCS score is: a. 2 b. 4. С. б. d. 9. e. 12. 15. A 20-year-old female who is at 32 weeks gestation is stabbed in the upper right chest. In the ED, her blood pressure is 80/60 mm Hg. She is gasping for breath, extremely anxious, and yelling for help. Breath sounds are diminished in the right chest. The most appropriate first step is to: a perform tracheal intubation. b. insert an oropharyngeal airway. c. perform needle or finger decompression of the right chest. d manually displace the gravid uterus to the left side of the abdomen. e Initiate two large caliber peripheral IV lines and crystalloid infusion.

Which of the following is a contraindication 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 19. A 56-year-old man is thrown violently against the steering wheel of his truck during a motor vehicle crash. On arrival in the ED, he is diaphoretic and complaining of chest pain. His blood pressure is 60/40 mm Hg and his respiratory rate is 40 breaths per minute. Which of the following best differentiates cardiac tamponade from tension pneumothorax as the cause of his hypotension? a Tachycardia b. Pulse volume c. Breath sounds d. Pulse pressure e. Jugular venous pressure 20. Bronchial intubation of the right or left mainstem bronchus can easily occur during infant endotracheal intubation because: a. the trachea is relatively short. b. the distance from the lips to the larynx is relatively shart. c, the use of cuffed endotracheal tubes eliminates this issue. d. the mainstem bronchi are less angulated in their relation to the trachea. e. so little friction exists between the endotracheal tube and the wall of the trachea.
