单项选择题
A 2-year-old client returns from surgery after a bowel resection as a result of Hirschsprung's disease. A temporary colostomy is in place. Which immediate postoperative nursing intervention takes priority ？（）
A．Changing the surgical dressing.
B．Suctioning the nasopharynx frequently to remove secretions.
C．Irrigating the colostomy with 100 ml of normal saline solution.
D．Auscultating lung sounds.
答案
参考答案：D
解析：
Immediately after surgery, the priority nursing intervention is assessing pulmonary function. The surgical dressing shouldn't require changing right away. Suctioning should be performed only if the client can't maintain a patent airway. Colostomy irrigation isn't warranted.
