问题 A.皮肤潮湿 B.脉搏饱满 C.血压升高 D.血pH降低 E.血浆渗透压显著升高 糖尿病酮症酸中毒的典型特征
选项
答案 D
解析 :(1)~(2)糖尿病酮症酸中毒时由于脱水明显,病人的皮肤干燥、脉细而微弱、血压降低,血浆渗透压可升高但如不合并高渗状况时不会明显增高,故只有血pH降低是其特征。单纯非酮症高渗糖尿病昏迷时,除有上述脱水的表现外,无酸中毒故血pH不降低,但以显著高血糖、高血钠所致的渗透压极度增高为特征。

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
