单项选择题
A client with heart failure develops pink frothy sputum, coarse crackles, and restlessness. Which of the following actions should the nurse take first ？（）
A．Check the client's blood pressure.
B．Place the client in high Fowler's position.
C．Calculate the client's fluid balance.
D．Notify the physician.
答案
参考答案：B
解析：
Proper positioning can help reduce venous return to the heart. High Fowler's position also decreases lung congestion. Checking the client's blood pressure is important but doesn't take top priority. Calculating the client's fluid balance wouldn't be an immediate priority in an emergency. Notifying the physician should be done after the client has been repositioned and assessed.
