Which set of aerial blood values describes a patient with paially compensated respiratory alkalosis after 1 month on a mechanical ventilator? pH ,HCO3- (mEq/L), Pco2 (mm Hg) (A) 7.65, 48, 45 (B) 7.50, 15, 20 (C) 7.40, 24, 40 (D) 7.32, 30, 60 (E) 7.31, 16, 33
High-Yield Explanation
The blood values in respiratory alkalosis show decreased Pco2 (the cause) and decreased and by mass action. The is fuher decreased by renal compensation for chronic respiratory alkalosis (decreased HCO3- reabsorption).
