ATLS® Written Pretest #1 10th Edition

ATLS® Written Pretest #1 10th Edition Disclaimer: Note: It is understood that medical practices vary with institutional policies and individual preferences. This test is designed in conjunction with the material presented in the 10th edition of the ATLS® Course. Please answer the questions accordingly. 1-1. 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: a. reexamine the chest. b. perform an aortogram. c. obtain a computed tomography (CT) scan of the chest. d. obtain arterial blood gas analyses. e. perform transesophageal echocardiography. 1-2. A construction worker falls two stories from a building and sustains bilateral calcaneal fractures. In the emergency department (ED), he is alert, his vital signs are normal, and he is complaining of severe pain in both heels and his lower back. Lower extremity pulses are strong and there is no other deformity. The suspected diagnosis is most likely to be confirmed by: a. angiography. b. compartment pressures. c. retrograde urethrogram. d. Doppler ultrasound studies. e. complete spine x-ray series. 1-3. Which of the following is true regarding the initial resuscitation of a trauma patient? a. A patient with a torso gunshot wound and hypotension should receive crystalloid fluid resuscitation until the blood pressure is normal. b. Evidence of improved perfusion after fluid resuscitation could include improvement in Glasgow Coma Scale (GCS) score on reevaluation. c. Massive transfusion is defined as transfusion of more than 10 units of packed red blood cells and plasma within 24 hours. d. When tranexamic acid is administered by prehospital providers, a second dose is required within 24 hours. e. Fluid resuscitation is far more important than bleeding control in trauma patients. 1-4. In managing a patient with a severe traumatic brain injury, the most important initial step is to: a. secure the airway. b. obtain a c-spine film. c. support the circulation. d. control scalp hemorrhage. e. determine the GCS score. 1-5. A previously healthy, 70-kg (154-pound) man suffers an estimated acute blood loss of 2 liters. Which statement applies to this patient? a. His pulse pressure will be widened. b. His urinary output will be at the lower limits of normal. c. He will have tachycardia but no change in his systolic blood pressure. d. 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.
