A. 7.45
B. 7.35
C. 7.3
D. 7.5 Correct Answer D. 7.5

is always caused by hyperventilation, which causes excessive
"blowing off" of CO2 and, hence, a decrease in the plasma
carbonic acid concentration. Causes include extreme anxiety,
, hypoxemia, early phase of salicylate intoxication, gram-negative
bacteremia, and inappropriate ventilator settings.
