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?
- switch oxygen to a nonrebreather mask
- increase oxygen to 70%
- place the client in high-fowlers position and encourage the use of incentive spirometer and coughing
- 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...
