How often should a patient be encouraged to TCDB postoperatively?

Encouraging a patient to perform turning, coughing, and deep breathing (TCDB) exercises every two hours postoperatively is crucial for several reasons. This routine helps prevent complications such as atelectasis, which is the collapse of part or all of a lung, and promotes the expansion of the lungs to maintain good respiratory function.

Postoperative patients are often at risk of developing respiratory issues due to factors like pain, immobility, and the effects of anesthesia. By practicing TCDB every two hours, patients can effectively clear secretions, improve lung aeration, and enhance oxygenation, all of which are essential for a smooth recovery.

The other options suggest less frequent intervals, which may not be sufficient to maintain optimal lung function and prevent complications. Encouraging these exercises too infrequently could lead to a higher risk of respiratory complications, making two hours the most appropriate and beneficial interval for postoperative care.
