问题 单项选择题 A1/A2型题

有关注射部位与吸收途径表述不恰当的是()

A.血管内给药没有吸收过程

B.肌内注射后药物以扩散和滤过两种方式转运

C.皮内注射吸收差,只适用于诊断和过敏试验

D.皮下注射可减少药物作用时间

E.腹腔注射可能影响药物的生物利用度

答案

参考答案:D

解析:除了血管内给药没有吸收过程外,其他途径如皮下、肌内、腹腔注射都有吸收过程。肌内注射后药物以扩散和滤过两种方式转运,一般吸收程度与静脉注射相当。皮下与皮内注射药物吸收较肌注慢,故需延长药物作用时间可采用皮下注射;皮内注射吸收更差,只适用于诊断和过敏性试验。腹腔注射后药物经门静脉首先进入肝脏,可能影响药物生物利用度。所以答案为D。

     More and more Chinese mainland buyers have in the past few weeks been queuing to cross the border into Hong Kong to lessen growing financial pressure led by rising food prices at home. Their shopping

baskets are full of sugar, salt and even tissue paper.

     While prices are rising so fast, many people are worrying out ways to cut down their expenses. Du Z

henqi, an 80-year-old Beijinger, grows different vegetables in the community yard. But this year, before they turned ripe, they were all picked by his neighbors. “The prices of vegetables have gone up dramatically,” said Du. “So I understand those people and it pleased me to offer them my help.” Du expressed his

sympathy for these who took away his vegetables without permission.

     The rise of food price in China has made people with low incomes feel serious financial pressure and

forced them to spend wisely.

     A collection of practical money-saving tips is thus becoming increasingly popular among Chinese

citizens. If you search “money-saving strategies” in Baidu, you will find 4.27 million entries in 0.19 seconds. The collection provides tips such as choosing local and seasonal products, avoiding buying vegetables on

rainy or snowy days when higher transport costs increase prices, using websites for purchases, and

planting vegetables on the balcony. Some consider buying in large quantity to stay within a tight budget.

     Fei Yuqin, who lives in Shanghai, frequently hurries to a farmers’ market before 6 a.m. to buy large

amounts of vegetables for her family and neighbors. “Instead of buying small amounts, I buy large amounts of vegetables at the market and get a 50-percent discount.”

     With these tips, many people have become experts in cutting household expenses. However, financial

pressure caused by the current round of price rising still troubles many Chinese people.
