问题 A.更换针头重新穿刺 B.适当提高输液瓶位置 C.调整针头位置 D.热敷注射部位上端血管 E.适当降低患者肢体位置 挤压近针头端的输液管,有阻力,无回血应
选项
答案 A
解析 1.发生静脉痉挛时,用热水袋或热毛巾热敷注射部位上端血管,以缓解静脉痉挛。2.针头斜面紧贴血管壁,妨碍液体滴入,可调整针头位置或适当变换肢体位置,直到滴注通畅为止。3.折叠滴管下输液管,同时挤压近针头端的输液管,若感觉有阻力,且无回血,则表示针头已阻塞,应更换针头重新穿刺。

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.
