The nurse is encouraging the postoperative patient to utilize diaphragmatic breathing. Which priority goal is the nurse trying to achieve?

A) Manage pain
B) Prevent atelectasis
C) Reduce healing time
D) Decrease thrombus formation

After surgery, patients may have reduced lung volume and may require greater effort to cough and deep breathe; inadequate lung expansion can lead to atelectasis and pneumonia. Purposely utilizing diaphragmatic breathing can decrease this risk. During general anesthesia, the lungs are not fully inflated during surgery and the cough reflex is suppressed, so mucus collects within airway passages. Diaphragmatic breathing does not manage pain; in some cases, if splinting and pain medications are not given, it can cause pain. Diaphragmatic breathing does not reduce healing time or decrease thrombus formation. Better, more effective interventions are available for these situations.
