以下各项关于加用碘剂对甲状腺大部切除术患者手术前用药的叙述中，不正确的是（）

A.碘剂的作用是便于手术操作，减少术中出血

B.常用制剂为复方碘溶液

C.每日3次，每次3～5滴，以后逐日每次增加1滴，至每次15滴

D.一般约4周（最多8周）

E.凡不准备施行手术治疗的患者，都不要服用碘剂

答案

参考答案：D

解析：药物准备的方法通常有三种：①甲亢症状较重者，先服用抗甲状腺药物，症状控制后停药改服碘剂；②甲亢症状较轻者可单用碘剂；③对抗甲状腺药物不能耐受或疗效不好的患者，常用制剂为复方碘溶液，一般约2周（不宜超过6周）。凡不准备施行手术治疗的患者，一律不要服用碘剂。可以手术的指征是患者情绪稳定、睡眠好转、体重增加；脉率<90次/分；基础代谢率<+20%；甲状腺腺体变硬缩小。故答案应选D。

Dear Liz，

My stay in Thailand has certainly been the experience of my life．

Life is busy and exciting．Bangkok is just like any other big city with a population of 10 million and heavy traffic．I'm very lucky because my host family is in a nice quiet area outside the city．There are Mr. and Mrs. Phairat, their son Sanan, who is 18, the daughter Chinda, who is 16, and Grandpa and Grandma．

I go to an international school with Sanan and Chinda．The school teaches about 70 percent in English，and 30 percent in Thai. I've learned some spoken language，but Thai writing is very difficult．The cooking lesson is my favourite．I'm learning all about Thai food and culture People don’t use chopsticks here，but spoons and forks．When I come back，I'm going to cook you a real Thai meal．

Last weekend we visited some temples．We also drove to Pattaya beach near Bangkok．I thought it was great，but Sanan and Chinda say that next month they’re taking me to Phuket Island，where the beaches are even more beautiful．The month after next，we’re going to travel to Mr．Phairat，s hometown in the north of Thailand．The Phairats own land there，and they have two elephants．I’m going to ride those elephants — and even wash them．Sanan and Chinda say it’s really fun．

I'm amazed by everything in this country，especially by the elephants．Elephants are an important pan of Thai culture and way of life．They have been a traditional symbol(象征)of Thailand for many years in times of war and peace．In the seventh century，a Thai king trained 20，000 elephants for battle．

I’ll tell you all about my Thai boxing(拳击)lessons next time I write．

Love,

Mandy
