ABG help!!!

  1. A nurse is caring for a client who is 1 day postoperative following an open thoracotomy. The client is receiving oxygen mist at 40% by face tent. The client's SiO2 is 89%. ABG results are pH 7.31, PaO2 93 mmHg, PaCO2 50 mmHg, HCO3 25 mEq/L. Which of the following is an appropriate action by the nurse?

    1. switch oxygen to a nonrebreather mask
    2. increase oxygen to 70%
    3. place the client in high-fowlers position and encourage the use of incentive spirometer and coughing
    4. position the client prone and have the respiratory therapist perform postural drainage

    I do not think the answer is 4, because there is no indication of the client needing postural drainage. I know the pH is acidic, the PaCO2 is acidic and the HCO3 is normal. This is respiratory acidosis. I think I would do 3...

    Help please!!!

    I'm going with "true," That's always the best guess when you don't know.

    What else is considered an abnormal value in the information you posted and what would be the first thing to consider to help correct that?

    Only one answer is a nursing intervention.

    You're on the right track.

    So, why would this patient be mildly acidotic and how might that be mitigated?
