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.
1-6. The physiological hypervolemia 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.
1-7. The best assessment of fluid resuscitation of the adult burn patient is:
a. urinary output of 0.5 mL/kg/hr.
b. normalization of blood pressure.
c. normalization of the heart rate.
d. measuring a normal central venous pressure.
e. providing 4 mL/kg/percent body burned/24 hours of crystalloid fluid.
1-8. The diagnosis of shock must include:
a. hypoxemia.
b. acidosis.
c. hypotension.
d. increased vascular resistance.
e. evidence of inadequate organ perfusion.
1-9. A 7-year-old boy is brought to the ED by his parents several minutes after he fell through a window.
He is bleeding profusely from a 6-cm wound in his medial right thigh. Immediate management of the
wound should consist of:
a. applying a tourniquet.
b. applying direct pressure on the wound.
c. packing the wound with gauze.
d. applying direct pressure on the femoral artery at the groin.
e. debriding devitalized tissue.
1-10. For the patient with severe traumatic brain injury, profound hypocarbia should be avoided to
prevent:
a. respiratory acidosis.
b. metabolic acidosis.
c. cerebral vasoconstriction with diminished perfusion.
d. neurogenic pulmonary edema.
e. shift of the oxyhemoglobin dissociation curve.
