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.

Answer and Explanation

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.
