Demonstrating deep breathing and coughing techniques to a postoperative client is an intervention that aligns well with the scope of practice for a practical nurse. This task is essential for patient education and recovery, especially after surgery, where respiratory function can be compromised. By engaging patients in deep breathing and coughing exercises, the practical nurse helps reduce the risk of postoperative complications such as pneumonia, aids in lung expansion, and promotes effective ventilation.

This intervention does not require advanced nursing assessment skills or complex decision-making, making it a fitting responsibility for a licensed practical nurse. Practical nurses are trained to provide direct patient care and education, which fits within their role, particularly in a postoperative setting where monitoring and supporting recovery is crucial.
