The nurse assists the patient to turn,breathe deeply,and cough every 2 hours to decrease the risk of postoperative atelectasis or pneumonia.The nurse assesses the wound drainage to monitor for signs of bleeding,infection,or wound complications.Vital signs are monitored to detect the potential for infection or hemorrhage,not to prevent them.The nurse may teach the patient about cancerous tumors; however,this intervention will not decrease the risk of postoperative complications.
