Which statement by a client shows understanding of preoperative teaching for turning, coughing, and deep breathing?

The statement about preventing pneumonia demonstrates a strong understanding of the importance of turning, coughing, and deep breathing in the preoperative setting. These actions are crucial for maintaining effective respiratory function and preventing complications after surgery.

After surgery, patients are often less mobile due to pain, anesthesia effects, or the surgical procedure itself, which can lead to respiratory issues such as pneumonia. Deep breathing exercises help to expand the lungs, ensuring that air reaches all areas of the lungs and helps to clear secretions that may accumulate. Coughing aids in expelling any mucus that could obstruct airways and lead to infections. Turning the patient periodically also promotes lung expansion and improves circulation, contributing to overall respiratory health.

While the other statements may have some relevance to general health and physiology, they do not directly address the key role that these actions play in preventing respiratory complications specifically associated with surgery.
