QUESTIONS WITH CORRECTLY
VERIFIED ANSWERS
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 2 liters of crystalloid solution 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. His breath sounds are
decreased in the left hemithorax, and after initial IV fluid
resuscitation, a closed tube thoracostomy is performed for decreased
left 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 CT scan of the chest.
d) obtain arterial blood gas analyses --SOLUTION--a) reexamine
the chest

a) priapism.
b) bradycardia.
c) diaphragmatic breathing.
d) presence of deep tendon reflexes. --SOLUTION--d)

likely to be confirmed by:
a) compartment pressures
