单项选择题
A client has a nasogastric tube inserted at the time of abdominal perineal resection with permanent colostomy. This tube will most likely be removed when the client demonstrates which of the following
A．Absence of nausea and vomiting.
B．Absence of stomach drainage for 24 hours.
C．Passage of mucus from the rectum.
D．Passage of flatus and feces from the colostomy.
答案
参考答案：D
解析：A sign indicating that a client's colostomy is open and ready to function is passage of feces and flatus. When this occurs, gastric suction is ordinarily discontinued, and the client is allowed to start taking fluids and food orally. Absence of bowel sounds would indicate that the tube should remain in place because peristalsis has not yet returned.
