is 30 mmHg, and pH is 7.21. The treatment of his acid-base disorder is best
accomplished by:
A. Hyperventilation
B. Restoration of normal perfusion
C. Initiation of low-dose dopamine
D. Administration of sodium bicarbonate
E. Initiation of phenylepinephrine infusion
, Answer: B
2. The highest priority in managing a patient whose injuries include closed

and his heart rate is 140 beats per minute. His hypotension is most likely due
to:
A. Tension pneumothorax
B. Massive hemothorax
C. Pericardial tamponade
