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.

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

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.

The physiologic hypervolemia of pregnancy has clinical significance in the management of the severely
injured, gravid woman by:

e.
providing 4 mL/kg/percent body burn/24 hours of crystalloid fluid Correct Answer- a.
Urine output of 0.5 mL/kg/hr

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:
