In the emergency department, 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:
2. Select one:
3. a.
4. perform tracheal intubation
5. b.
6. insert an oropharyngeal airway
7. c.
8. perform needle or finger decompression of the right chest
9. d.
10. manually displace the gravid uterus to the left side of the abdomen
11. e.

13. perform needle or finger decompression of the right chest
14. A 22-year-old female athlete is stabbed in her left chest at the third interspace in the
anterior axillary line. On admission to the ED and 15 minutes after the incident, she is
awake and alert. Her heart rate is 100 beats per minute, blood pressure is 80/60 mm
Hg, and respiratory rate is 20 breaths per minute. A chest x-ray reveals a large left
hemothorax. A left chest tube is placed with an immediate return of 1600 mL of
blood. The next management step for this patient is to:
15. Select one:
16. a.
17. perform a thoracoscopy
18. b.
19. perform an arch aortogram
20. c.
21. insert a second left chest tube

26. prepare for an exploratory thoracotomy
27. A 22-year-old man is hypotensive and tachycardic after a shotgun wound to the left
shoulder. His blood pressure is initially 80/40 mm Hg. After initial fluid resuscitation
his blood pressure increases to 122/84 mm Hg. His heart rate is now 100 beats per
minute and his respiratory rate is 28 breaths per minute. A tube thoracostomy is
performed for decreased left chest breath sounds with the return of a small amount of
blood and no air leak. After chest tube insertion, the most appropriate next step is:
28. Select one:
29. a.
, 30. reexamine the chest
31. b.
32. perform an aortogram
33. c.
34. obtain a CT scan of the chest
35. d.
36. obtain arterial blood gas analyses
37. e.
38. perform transesophageal echocardiography - ANS-A) Reexamine the chest
39. A 22-year-old man sustains a gunshot wound to the left chest and is transported to a
small community hospital; no surgical capabilities are available. In the emergency
department, a chest tube is inserted and 700 mL of blood is evacuated. The trauma
center accepts the patient in transfer. Just before the patient is placed in the
ambulance for transfer, his blood pressure decreases to 80/68 mm Hg and his heart
rate increases to 136 beats per minute. The next step should be to:
40. Select one:
41. a.
42. clamp the chest tube
43. b.
44. cancel the patient's transfer
45. c.
46. perform an emergency department thoracotomy
47. d.
48. repeat the primary survey and proceed with transfer

51. repeat the primary survey and proceed with transfer
52. A 23-year-old man sustains 4 stab wounds to the upper right chest during an
altercation and is brought by ambulance to a hospital that has full surgical
capabilities. His wounds are all above the nipple. He is endotracheally intubated,
closed tube thoracostomy is performed, fluid resuscitation is initiated through 2
large-caliber IVs. FAST exam does not reveal intraabdominal injuries. 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% O2). 1500 mL of blood has drained
from the right chest. The most appropriate next step in managing this patient is to
53. Select one:
54. a.
55. perform diagnostic peritoneal lavage
56. b.
57. obtain a CT of the chest
58. c.
59. perform an angiography
60. d.
61. urgently transfer the patient to the operating room
62. e.
