     Happiness is for everyone. You don't need to care about those people who have beautiful houses with

large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why?

Because those who have big houses may often feel lonely and those who have cars may want to walk on

the country roads at their free time.

     In fact, happiness is always around you if you put your heart into it. When you are in trouble at school,

your friends will help you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you

will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness

is always around you.

     Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also

say you are very happy, because you have something else that can't be bought with money. When you

meet with difficulties, you can say loudly you are very happy, because you have more chances to

challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes,

"Life is like a revolving door. When it closes, it also opens. If you take every chance you get, you can be

a happy and lucky person."

王先生，男，52岁，来到社区卫生中心，希望社区护士给予其弟弟帮助。王先生主诉的情况是：“弟弟王冰，男，50岁，2年前，医院确诊为重症肌无力，每周一次由其妻陪同去医院就诊。需要完全由他人照顾和护理的弟弟最近夜间痰量增多，出现咳痰困难，弟媳因护理负担加重，因此带来的疲劳加重。”王先生担心这样继续下去会拖垮家庭，来站请求社区护士的援助。

当家庭访视进行两个月时，主治医师说：“由于病情逐渐加重，考虑今后病情会有突然恶化的可能，再者说，其妻子护理负担过重，希望住院治疗。”此时的社区护士最应优先做什么事情？
