Which of the following best describes the key to effective postoperative breathing exercises?

The key to effective postoperative breathing exercises lies in the ability to perform deep and effective coughs. Following surgery, patients may have diminished lung capacity and reduced respiratory function due to pain, immobility, or anesthesia effects. Deep breathing and coughing exercises help to expand the lungs, promote the clearance of secretions, and prevent complications such as atelectasis and pneumonia.

Encouraging deep breaths helps to open up the alveoli, improve ventilation, and enhance oxygenation. Furthermore, effective coughing aids in expelling mucus or any other secretions that may block airways. This combination not only supports lung health but also aids in the overall recovery process after surgery.

While other options might suggest aspects of care that could support respiratory function, they do not address the essential components of breathing exercises in the immediate postoperative phase as effectively as deep and effective coughing.
