A nurse is preparing to administer oxygen therapy to a patient who has just undergone abdominal surgery. Which of the following interventions is most important to ensure proper oxygenation?
Encourage the patient to take deep breaths and use an incentive spirometer regularly.
Set the oxygen flow rate based on the patient's subjective feeling of breathlessness.
Administer oxygen at 6 L/min through a nasal cannula without an order.
Place the patient in a Trendelenburg position to facilitate oxygen delivery.
The Correct Answer is A
A. Encouraging deep breaths and using an incentive spirometer can help prevent atelectasis and improve oxygenation after surgery, as it encourages lung expansion.
B. Setting the oxygen flow rate based on subjective breathlessness is not ideal; oxygen should be administered according to established protocols and patient need.
C. Administering oxygen without an order is not appropriate and could lead to oxygen toxicity.
D. The Trendelenburg position is not necessary for oxygenation and could lead to increased pressure on the abdomen and respiratory distress.

Explanation
A. Increasing the oxygen flow rate due to anxiety can worsen carbon dioxide retention, which is dangerous in COPD patients.
B. High-flow oxygen is typically not recommended for COPD patients because it can suppress respiratory drive.
C. Monitoring the respiratory rate and effort is crucial to ensure the patient is not retaining carbon dioxide or experiencing further respiratory distress.
D. Adjusting the oxygen flow rate to maintain a saturation level of 88-92% is recommended for COPD patients to prevent hypercapnia.
E. A non-rebreather mask is generally not used for COPD patients, as it can deliver too much oxygen, leading to carbon dioxide retention.
F. Encouraging deep breathing can help, but it is more important to focus on maintaining the proper oxygen saturation.
