问题 单项选择题 B1型题

低渗性缺水引起体液容量的变化为()

A.以血液浓缩为主

B.只有组织间液减少

C.血浆、组织间液、细胞内液都减少,以血浆减少为主

D.血浆、组织间液、细胞内液都减少,以细胞内液减少为主

E.血浆、组织间液、细胞内液都减少,以组织间液减少为主

答案

参考答案:E

解析:低渗性缺水时,水和钠同时缺失,但缺水少于缺钠,尿量增多,细胞外液量减少。组织间液进入血循环,使组织间液的减少超过血浆的减少。而当等渗性缺水时,水和钠成比例地丧失,细胞外液减少,细胞内液量变化不大,血液浓缩表现明显,故低渗性缺水时的变化为血浆、组织间液、细胞内液都减少。等渗性缺水时的变化为A。
