During preoperative preparation, the practical nurse (PN) should offer the client which explanation about why deep breathing exercises with an incentive spirometer are necessary after surgery?

A. Incentive spirometry is uncomfortable but necessary for your postoperative care: This statement is negative and does not explain the purpose, which may discourage use. B. Deep breathing exercises using the spirometer will help prevent postoperative complications: Positive explanation that reinforces the importance of lung expansion and prevention of atelectasis or pneumonia. C. Failure to keep your lungs working may result in pneumonia and death: While partially true, this statement is fear-based and not therapeutic. D. You will use the spirometer for the first postoperative day only: Incentive spirometry is used for several days post-op until mobility and breathing patterns normalize.
