单项选择题
The immobile adolescent with a recent fractured femur suddenly complains chest pain, dyspnea, diaphoresis, and tachycardia. Which of the following would the nurse suspect()
A. Atelectasis.
B. Pneumonia.
C. Pulmonary edema.
D. Pulmonary emboli.
答案
参考答案：D
解析：
Chest pain and dyspnea in an immobilized adolescent with a large bone fracture suggest a fat embolus. With this condition, fat droplets, rather than a thrombus, are transferred from the marrow into the general blood stream by the venous-arterial route, possibly reaching the lung or brain.
