Emergency medical technicians transport a 28-year-old iron worker to the emergency department. They tell the nurse, "He fell from a two-story building. He has a large contusion on his left chest and a hematoma in the left parietal area. He has a compound fracture of his left femur and he’s comatose. We intubated him and he’s maintaining an arterial oxygen saturation of 92% by pulse oximeter with a manual-resuscitation bag. " Which intervention by the nurse has the highest priority（）
A. Assessing the left leg.
B. Assessing the pupils.
C. Placing the client in Trendelenburg’s position.
D. Assessing level of consciousness.
参考答案：A
解析：
In the scenario, airway and breathing are established so the nurse’s next priority should be circulation. With a compound fracture of the femur, there is a high risk of profuse bleeding; therefore, the nurse should assess the site. Neurologic assessment is a secondary concern to airway, breathing, and circulation. The nurse doesn’t have enough data to warrant putting the client in Trendelenburg’s position.
