During deep breathing and coughing exercises, which statement is false?

In the context of deep breathing and coughing exercises, inhaling through pursed lips is not the typical approach. This exercise primarily focuses on maximizing lung expansion and promoting effective breathing patterns.

Inhaling deeply through the nose helps ensure that the breath is deep and intentional, which is crucial for the exercises aimed at clearing secretions and improving lung function. Sitting comfortably is essential for facilitating effective breathing mechanics, allowing for a relaxed posture that supports optimal lung expansion. Additionally, the use of a pillow over an incision can help provide support and reduce discomfort, particularly when coughing, which could strain the surgical site.

Each of these practices plays a significant role in the efficacy of the exercises, making the inhalation through pursed lips an inaccurate representation of correct technique in this scenario.
