A patient is admitted to the emergency department (ED) in respiratory distress.The results of his first arterial blood gases were pH = 7.30; PCO₂ = 40; HCO₃ = 19 mEq/L; PO₂ = 80.The nurse evaluates the patient's treatment plan by examining repeat arterial blood gases (ABGs) .The results are pH = 7.38; PCO₂ = 32; HCO₃ = 19 mEq/L.The nurse concludes which of the following?

A) Respiratory acidosis; the treatment plan is ineffective.
B) Metabolic alkalosis; the treatment plan is effective.
C) Partial compensation; the treatment plan is ineffective.
D) Complete compensation; the treatment plan is effective.

Final Answer : D , Explanation :  Complete compensation has occurred as the PCO 2  has returned the pH to the normal range.This change indicates that the treatment plan is effective.Partial compensation would be indicated by changes in the PCO 2  but the pH would still be outside the normal range.The ABG is now complete compensation metabolic acidosis.
