单项选择题
A client is admitted to the emergency department with complaints of chest pain and shortness of breath. The nurse's assessment reveals jugular vein distention. The nurse knows that when a client has jugular vein distention, it's typically due to
A．a neck tumor.
B．an electrolyte imbalance.
C．dehydration.
D．fluid overload.
答案
参考答案：D
解析：Fluid overload causes the volume of blood within the vascular system to increase. This increase causes the veins to distend and can be seen most obviously in the neck veins. An electrolyte imbalance may result in fluid overload, but it doesn't directly contribute to jugular vein distention.
