The nurse is providing care to a client on a medical-surgical unit.The client's arterial blood gas analysis is as follows: PaO₂ of 82,PaCO₂ of 49,HCO₃ of 26,and pH of 7.55.Which acid-base imbalance is this client experiencing based on this data?

A) An arterial blood gas analysis is often prescribed for client's experiencing alterations in oxygenation. Both the pH and the carbon dioxide levels represent acidosis. Furthermore, the carbon dioxide levels are regulated by the lungs. Therefore, a blood gas that has a pH greater than 7.45 indicates acidosis. If the same blood gas has a carbon dioxide greater than 45 mmHg, respiratory acidosis is present. The PaO₂ of 82 is on the low end of normal and the bicarbonate level is normal.
