患者，男性，60岁。高血压病史20年，因脑梗死住院治疗，以下可能出现的体征是（）。

（15分）某校兴趣小组同学进行常见酸、碱、盐的性质实验时，发现实验台上摆放的药品中，有一瓶装有溶液的试剂瓶未盖瓶盖且标签破损（如下图），于是决定对这瓶溶液进行探究：

（1）查阅资料:

①酸、碱、盐的性质实验中用到含有钠元素的物质是氯化钠、氢氧化钠、碳酸钠；

②氯化钙溶液呈中性

（2）对这瓶溶液到底是氯化钠、氢氧化钠、碳酸钠中的哪一种，同学们根据现有的药品进行如下实验：

①甲同学取待测液于试管中，滴加无色酚酞试液，溶液呈红色，由此得出结论：该溶液不可能是         溶液，理由是                                 。

②乙同学另取待测液于试管中，滴加稀盐酸，有            的现象，由此得出结论：该溶液是Na₂CO₃溶液。

③丙同学认为乙同学的结论不严密，因为NaOH溶液露置在空气中，会与         反应生成Na₂CO₃，反应的化学方程式为                                       ，所以这瓶溶液还可能是部分变质的NaOH溶液。

④对这瓶溶液的实际成分，小组同学讨论后，一致认为还需要进行如下实验：

设计步骤Ⅰ的目的是：完全除去溶液中的      ，避免其对     的检验造成干扰。

【实验结论】该溶液是                      。

（3）拓展运用：

①做实验时，取用药品后应及时               。

②NaOH溶液与盐酸发生中和反应，是        （选填“吸热”或“放热”）反应。

③除去NaOH溶液中混有的少量Na₂CO₃溶液，可加入适量的      溶液（填序号）。

Dear Edward,

I have been very busy recently with some really exciting new developments．If you visit my main website you will see various new items there．

The first is a tab called Food for Thought．This is a short daily email which raises a question or makes a statement or provides something for you to think about．Some regular readers may find these emails quite basic．However, you would agree with me that there are many people who reject anything spiritual simply because it means venturing(冒险进入) into the unknown．

There is also a tab called Please Help Me．I will be hosting tele-discussions soon-yes, and I am really excited about that!

Here I ask you to propose topics for tele-discussions．If you are concerned about missing out, don’t worry．The proceeds will be recorded and made available as MP3 recordings．Please let me know what burning issues you have or what you are curious about． 

I am providing a free mystery gift to the value of £9.95 for each successful suggestion． And please don’t think your issue is meaningless-there may be a number of other people who may have the same issue．

You may not be aware that I have also published a number of guided meditations(思考) on-line．Please have a look at this website for a free guided meditation as well as an explanation of what meditation is about．

And watch this space for more exciting things to come in the next month．I am now in a space where my hobby has become my work-how lucky can a girl be!

I also want to thank you for your support and interest over the past years-you have helped me immensely on my own journey．

Love and Light,

Elsabe
