问题 单项选择题 A1/A2型题

男性,22岁。2天前左季肋部被打伤,当时仅感伤部疼痛,仍可工作。次日伤部疼痛逐渐加重,仍勉强工作。今下午突然出现腹剧痛晕倒在地。查体:P120次/分,BP80/60mmHg。面色苍白,痛苦面容,被迫体位。全腹压痛,反跳痛明显,以左上腹为甚。诊断首先要考虑()。

A.急性脾破裂

B.延迟性脾破裂

C.肝破裂

D.肠系膜血管破裂

E.肾破裂

答案

参考答案:B

解析:脾脏质地脆弱,是腹内脏器中最易受伤的器官。脾损伤分为中央型破裂、被膜下破裂和真性破裂。前两种因被膜完整,出血量受到限制,可无失血性休克的表现,但仍有潜在的延迟性破裂可能性,如不注意绝对卧床休息,即使在微弱的外力作用下,也可发生严重的内出血。延迟性脾破裂是由脾中央破裂和被膜下破裂发展而形成的真性脾破裂,常因前期症状不典型,病情先轻后重,起病初期很难引起患者和医师的重视而易造成误诊或漏诊。

Britain’s undeclared general election campaign has already seen the politicians trading numbers as boxers trade punches. There is nothing new in such statistical slanging matches(相互谩骂)What is new is an underestimation of worry about what has been happening to official statistics under the Labour government.

One of the most important figures for Gordon Brown when presenting his pre-election budget on March 16th was the current-budget balance. This is the gap between current revenues and current spending. It matters to the chancellor of the exchequer(财政部长) because he is committed to meeting his own "golden rule" of borrowing only to invest, so he has to ensure that the current budget is in balance or surplus over the economic cycle.

Mr. Brown told MPs that he would meet the golden rule for the current cycle with £ 6 billion ($11.4 billion) to spare—a respectable-sounding margin, though much less than in the past. However, the margin would have been halved but for an obscure technical change announced in February by the Office for National Statistics to the figures for road maintenance of major highways. The ONS said that the revision was necessary because it had been double-counting this spending within the current budget.

If this were an isolated incident, then it might be disregarded. But it is not the first time that the ONS has made decisions that appear rather convenient for the government. Mr. Brown aims to meet another fiscal rule, namely to keep public net debt below 40% of GDP, again over the economic cycle. At present he is meeting it but his comfort room would be reduced if the S 21 billion borrowings of Network Rail were included as part of public debt. They are not thanks to a controversial decision by the ONS to classify the rail-infrastructure corporation within the private sector, even though the National Audit Office, Parliament’s watchdog, said its borrowings were in fact government liabilities.

This makes it particularly worrying that the official figures can show one thing, whereas the public experiences another. One of the highest-profile targets for the NHS is that no patient should spend more than four hours in a hospital accident and emergency department. Government figures show that by mid-2004, the target was being met for 9696 of patients. But according to a survey of 55,000 patients by the Healthcare Commission, an independent body, only 77% of patients said they stayed no more than four hours in A&E.

One way to help restore public confidence in official statistics would be to make the ONS independent, as the Conservatives and Liberal Democrats have suggested. Another would be for the National Audit Office to assess how the government has been performing against targets, as the Public Administration Committee has recommended.

It can be inferred from the first paragraph that()

A. the British politicians are often compared to boxers by the people

B. it is a common practice that the government plays with figures

C.people often overestimate the credibility of official statistics

D. the Labor government usually underestimate its official figures
