问题 单项选择题 A1/A2型题

严重急性肾功能衰竭少尿期治疗中,不正确的是()

A.限制钾的摄入

B.限制水-钠的摄入

C.限制蛋白质的摄入

D.早期给予透析治疗

E.用洋地黄制剂纠正容量负荷过多引起的心衰

答案

参考答案:E

解析:急性肾衰少尿期,过多的水分进入身体常引起水中毒,从而发生肺水肿。处理应以限制水、钠摄入、积极透析脱水为主;此时的肺水肿,如不恰当的使用洋地黄制剂,即有可能发生洋地黄制剂中毒(肾功衰竭排泄受限、钾平衡紊乱、肾衰本身的消化道症状影响对中毒症状的观察等),同时由于肺水肿的主要原因是容量过多,而不单纯是心肌收缩无力,使用洋地黄制剂相当于鞭打疲马,既起不到预期的作用,又很难掌握合适的剂量。
