ATLS Test 1 Latest With Complete Solution 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: Select one: a. reexamine the chest b. perform an aortogram c. obtain a CT scan of the chest d. obtain arterial blood gas analyses e. perform transesophageal echocardiography Correct Answer- A) Reexamine the chest A construction worker falls two stories from a building and sustains bilateral calcaneal fractures. In the emergency department, he is alert, 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: Select one: a. angiography b. compartment pressures c. retrograde urethrogram d. Doppler ultrasound studies e. complete spine x-ray series Correct Answer- e) Complete spine x-ray series Which of the following is true regarding the initial resuscitation of a trauma patient? Select one: a. A patient that presents with a torso gunshot wound and is hypotensive 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 score on reevaluation c. Massive transfusion is defined as transfusion of more than >10 of packed red blood cells and plasma in 24 hours d. When tranexamic acid is administered by pre-hospital providers a second dose is required within 24 hours e. Fluid resuscitation is far more important than bleeding control in trauma patients Correct Answer- b. Evidence of improved perfusion after fluid resuscitation could include improvement in Glasgow coma scale score on reevaluation In managing a patient with a severe traumatic brain injury, the most important initial step is to: Select one: a. Secure the airway b. obtain a c-spine film c. support the circulation d. control scalp hemorrhage e. determine the GCS score Feedback Your answer is corr Correct Answer- a. Secure the airway A previously healthy, 70-kg (154-pound) man suffers an estimated acute blood loss of 2 liters. Which one of the following statements applies to this patient? Select one: 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 ABG would demonstrate a base deficit between -6 and -10 mEq/L e. His systolic blood pressure will be maintained with an elevated diastolic pressure. Correct Answer- d. An ABG would demonstrate a base deficit between -6 and -10 mEq/L The physiologic hypervolemia of pregnancy has clinical significance in the management of the severely injured, gravid woman by: Select one: 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 Correct Answer- e. increasing the volume of blood loss to produce maternal hypotension The best assessment of fluid resuscitation of the adult burn patient is: Select one: a. Urine 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 burn/24 hours of crystalloid fluid Correct Answer- a. Urine output of 0.5 mL/kg/hr The diagnosis of shock must include: Select one: a. hypoxemia b. acidosis c. hypotension d. increased vascular resistance e. evidence of inadequate organ perfusion Correct Answer- e. evidence of inadequate organ perfusion A 7-year-old boy is brought to the emergency department by his parents several minutes after he fell through a window. He is bleeding profusely from a 6-cm wound of his medial right thigh. Immediate management of the wound should consist of: Select one: a. application of a tourniquet b. direct pressure on the wound c. packing the wound with gauze d. direct pressure on the femoral artery at the groin e. debridement of devitalized tissue Correct Answer- b. direct pressure on the wound For the patient with severe traumatic brain injury, profound hypocarbia should be avoided to prevent: Select one: a. respiratory acidosis b. metabolic acidosis c. cerebral vasoconstriction with diminished perfusion d. neurogenic pulmonary edema e. shift of the oxyhemoglobin dissociation curve Correct Answer- c. cerebral vasoconstriction with diminished perfusion After being involved in a motor vehicle crash, a 25-year-old man is brought to a hospital that has surgery capabilities available.. Computed tomography of the chest and abdomen 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: Select one: a. obtain contrast angiography b. transfer to a higher level trauma center c. perform an exploratory laparotomy d. infuse additional crystalloid fluids e. Obtain transesophageal echocardiography Correct Answer- c. perform an exploratory laparotomy Which one of the following statements regarding abdominal trauma in the pregnant patient is TRUE? Select one: a. The fetus is in jeopardy only with major maternal 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. Correct Answer- b. Leakage of amniotic fluid is an indication for hospital admission. The first maneuver to improve oxygenation after chest injury is to: Select one: 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 Correct Answer- c. administer supplemental
