This report concerns the perioperative nursing experience of a male patient undergoing surgery for gastric cancer and postoperative self-care. Gordon's 11 functional health patterns was used to assess the patient and determined that the patient was prone to anxiety, had a high risk of injury and infection, and the lack of specific knowledge regarding his condition. The patient was provided with an appropriate nursing care plan and intervention to meet his physical and mental needs, in order to alleviate feelings of anxiety, agitation, and pressure. This was provided for the nurses' professional knowledge and skills in the operating room. This helped the patient undergo the operation in a comfortable environment and led to earlier recovery of his former quality of life.
