Question 1 of 5
A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arterial blood gas (ABG) values include: pH 7.22 PaCO2 68 mm Hg Base excess -2 PaO2 78 mm Hg Oxygen saturation 80% Bicarbonate 28 mEq/L. Which of the following interpretations of the ABG values should the nurse make?
Correct Answer: B
Rationale: The low pH (7.22) and elevated PaCO2 (68 mm Hg) indicate respiratory acidosis, as the accumulation of carbon dioxide lowers the blood pH. The bicarbonate level is slightly elevated, suggesting partial compensation, but not indicative of metabolic alkalosis or acidosis.
