单项选择题
While assessing a 2-month-old child’s airway, the nurse finds that the child isn’t breathing. After two unsuccessful attempts to establish an airway, the nurse should（）
A. attempt rescue breaths.
B. attempt to reposition the airway a third time.
C. administer five back blows.
D. attempt to ventilate with a handheld resuscitation bag.
答案
参考答案：C
解析：
The child’s airway is blocked despite attempts to establish it. The next step is to clear the airway with back blows and chest thrusts. Breaths can’t be administered until the airway is patent. After two attempts to position the airway, the nurse can assume the airway is blocked. The nurse can’t ventilate the child with a handheld resuscitation bag until the airway is patent.
