单项选择题
The nurse is caring for a client who required chest tube insertion for a pneumothorax. To assess a client for pneumothorax resolution, the nurse can anticipate that he’ll require（）
A. monitoring of arterial oxygen saturation (SaO2).
B. arterial blood gas (ABG) studies.
C. chest auscultation.
D. a chest X-ray.
答案
参考答案：D
解析：
Chest X-ray confirms diagnosis by revealing air or fluid in the pleural space. SaO2 values may initially decrease with a pneumothorax, but they typically return to normal in 24 hours. ABG levels may show hypoxemia, possibly with respiratory acidosis and hypercapnia not related to a pneumothorax. Chest auscultation will determine overall lung status, but it’s difficult to determine if the chest is reexpanded sufficiently.
