64. A nursing student asks an RN for an example of an arterial blood gas result that demonstrates compensation for acidosis has occurred. The correct pH example would be:
64. A nursing student asks an RN for an example of an arterial blood gas result that demonstrates compensation for acidosis has occurred. The correct pH example would be:
. pH = 7.36; PaCO2 = 33; HCO3 = 20.
. pH = 7.30; PaCO2 = 60; HCO3 = 28.
. pH = 7.46; PaCO2 = 34; HCO3 = 22.
. pH = 7.44; PaCO2 = 48; HCO3 = 30.
Test-Taking Tip
Look for the pH to be within normal limits (7.35 to 7.45).

Answer 1 is correct because compensation is evident when the pH is within the normal range (7.35 to 7.45) and one of the other components is outside of normal. Both the bicarbonate (normal is 22 to 26) and CO2 (normal: 35 to 45) are below the normal range. Answer 2 is incorrect because this sample is outside the normal range, so that compensation has not occurred. Answer 3 is incorrect because the pH is outside the normal range of 7.35 to 7.45. Answer 4 is incorrect because the pH in this sample is within the normal range, but on the alkaline side, not the acidotic side.
