问题 传导性聋气骨导间距最大不超过
选项 A.10dB B.20dB C.40dB D.60dB E.70dB
答案 D
解析 :传导性聋时,各频率骨导听阈正常或接近正常;气导听阈提高;气骨导间距大于10dB,一般不大于40dB(HL),最大不超过60dB。一般传导性聋气骨导差达到60dB时,要考虑有无测试误差。

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.
