(A+ Graded 100% Verified Answers)
A 22yo man is hypotensive and tachycardic after a shotgun wound to the left shoulder. His
BP is initially 80/40mm Hg. After initial fluid resuscitation his BP increases to 122/84 mm
Hg. His HR is now 100bpm and his RR 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 - re-examine the chest
B - perform an aortogram
C - obtain a CT scan of the chest
D - obtain arterial blood gas analysis
E - perform transesophageal echocardiography - ANSWER✅ A - re-examine the chest
A construction worker falls two stories from a building and sustains bilateral calcaneal
fractures. In the ED, he is alert, vital signs are normal, and he is complaining of severe pain
in both heels and his lower back. Lower extremity pulss 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 US studies

E - complete spine XR series - ANSWER✅ E - complete spine XR series
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 BP 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 units of packed red blood
cells and plasma within 24 hours.
D - When tranexamic acid is adminstered 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. -
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:
A - secure the airway
B - obtain a c-spine film
C - support the circulation
D - control scalp hemorrhage
E - determine the GCS score - ANSWER✅ A - secure the airway

A previously healthy, 70kg (154 lb) man suffers an estimated acute blood loss of 2 liters.
Which of the following statements 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 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. -
ANSWER✅ D - An ABG would demonstrate a base deficit between -6 and -10 mEq/L.
The physiological hypervolemia of pregnancy has clinical significance in the management of
the severely injured, gravid women 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 - ANSWER✅ E -
increasing the volume of blood loss to produce maternal hypotension
The best assessment of fluid resuscitation of the adult burn patient is:
A - urinary output of 0.5 mL/kg/hr
