A client has respiratory acidosis. The nurse evaluates that treatment is being effective with which arterial blood gas values?
a. pH 7.28, HCO3– 12 mEq/L, PCO2 45 mm Hg, PO2 96 mm Hg
b. pH 7.32, HCO3– 17 mEq/L, PCO2 25 mm Hg, PO2 98 mm Hg
c. pH 7.35, HCO3– 36 mEq/L, PCO2 65 mm Hg, PO2 78 mm Hg
d. pH 7.48, HCO3– 12 mEq/L, PCO2 35 mm Hg, PO2 85 mm Hg
C
A pH of 7.35 is normal, indicating acid-base balance (fully compensated). A respiratory problem with carbon dioxide retention and inadequate gas exchange is apparent from the high PCO2 and the low PO2 . The bicarbonate level is greatly elevated, indicating renal synthesis and reabsorption of HCO3–, a powerful acid-base compensatory mechanism. Thus, the amount of bicarbonate (base) in the blood adequately compensates for the increased carbon dioxide level, so that the pH is normal, although no other arterial blood gas value is normal.
