单项选择题
Which of these signs suggests that a client with syndrome of inappropriate antidiuretic hormone (SIADH) secretion has developed complications（）
A. Tetanic contractions.
B. Neck vein distention.
C. Weight loss.
D. Polyuria.
答案
参考答案：B
解析：
SIADH causes antidiuretic hormone overproduction and leads to fluid retention. Severe SIADH can cause such complications as vascular fluid overload, which is signaled by neck vein distention. Tetanic contractions aren’t associated with this disorder, but weight gain and fluid retention from oliguria are.
