The Correct Answer is A

Whatever side of 7.4 the pH is on, the process that caused it to shift to that side is the primary abnormality.

Identify whether the PCO2 is normal, inappropriate, and whether there is a respiratory acidosis or alkalosis (i.e. the CO2 could be in the normal range but is the patient tachypneic and is CO2 inappropriately high).
  • For acute increases in PCO2 of 10 mm Hg there should be a rise of 0.08 in the pH.
  • For acute decreases in PCO2 of 10 mm Hg there should be a fall of 0.08 in the pH.
