问题 单项选择题 A1/A2型题

肝硬化患者Child-Pugh分级总分是多少评估为A级()。

A.≤4分

B.≤5分

C.≤6分

D.≤7分

E.≤8分

答案

参考答案:C

解析:肝硬化患者Child-Pugh分级标准包括5个指标:肝性脑病、腹水、总胆红素、白蛋白、凝血酶原时间,其中每个指标分成3个等级,具体如下:无肝性脑病记1分,肝性脑病1~2级记2分,3~4级记3分;无腹水记1分,轻度腹水记2分,中至重度腹水记3分;总胆红素<34μmol/L记1分,在34~51μmol/L之间记2分,>51μmol/L记3分;白蛋白≥35g/L记1分,在28~35g/L之间记2分,白蛋白≤28g/L记3分;凝血酶原时间延长1~3秒记1分,延长4~6秒记2分,延长>6秒记3分。注:PBC或PSC时,总胆红素<68μmol/L记1分,68~170μmol/L记2分,>170μmol/L记3分。将5个指标计分进行相加,根据该总和的多少将肝脏储备功能分为A、B、C三级,总分≤6分为A级,7~9分为B级,≥10分为C级。分数越高,提示肝脏储备功能越差。

阅读下列短文,从每篇短文后所给各题的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

The fog was so thick that I couldn't see the man next to me. We were led down a road to the base of a hill. An officer, unknown to us, explained that the command wanted us to spread out on the road and fix bayonets(刺刀).When the signal was given, we were to creep up the hill and take the enemy by surprise with a bayonet attack.

I didn't think too much of the idea and about a dozen fellows agreed with me, but we lost in the vote. Some others didn't have bayonets and declared that the orders didn't apply to them, but their idea, too, was denied.

Up the hill we went, feeling our way along the ground with our feet. Step by step we advanced. It seemed like an ugly dream, but I knew it was all too real. I looked to my right and to my left to find any sign of my fellows. Much to my surprise, I could make out unclear forms on each side of me. I could hear whispers all along the line and louder orders to shut up!

While we were standing around arguing, the fog suddenly disappeared, just like somebody waved a magic wand(杖).We were caught out in the open with no cover in sight. The Chinese had been caught by surprise. Both sides just stared at each other, not knowing what was going on. A single shot rang out and somebody blew a whistle and shouted "Retreat"(撤退).We rushed out at full speed down the hill.

I don't speak or understand Chinese, but from behind us I could understand joyful laughter!
