1公式与方法

感染控制与患者安全

方法

  1. 对每位患者都从标准预防开始:手卫生、针对预期暴露的个人防护装备、安全使用锐器。
  2. 按传播途径追加预防措施:接触传播(隔离衣、手套)、飞沫传播(外科口罩)、空气传播(N95、负压病房)。
  3. 保持无菌物品的无菌状态:如有疑问就视为不无菌;更换,绝不擦拭。
  4. 预防环境中的伤害:防跌倒措施,约束仅作为最后手段,火灾时用 RACE 和 PASS。
  5. 核对给药的正确原则、两个身份识别信息,以及对高警示药物的额外保障;报告差错和险兆事件。

  2. BWarmth sterilizes the surgical site
  3. CWarm patients do not need antibiotic prophylaxis
  4. DLow body temperature reduces blood flow and immune function in the wound
2.感染控制与患者安全困难

  1. A将该无菌区视为已污染,重新铺设
  2. B继续操作,因为同事没有碰到任何无菌物品
  3. C只移除手臂经过处最近的物品
  4. D用无菌巾盖住该区域,并在其上继续操作
3.护理学基础中等

In adult basic life support, how long should the rescuer take to check for normal breathing?

  1. AAs long as it takes to be certain
  2. BAt least one minute
  3. CNo more than 10 seconds
  4. DAbout 30 seconds
4.护理学基础困难

  2. BStreptococcus pyogenes
  3. CClostridium tetani
  4. DPseudomonas aeruginosa
6.微生物学困难

3溶液

1.感染控制与患者安全

答案: D · Low body temperature reduces blood flow and immune function in the wound

为什么是这个答案

Hypothermia causes vasoconstriction and less oxygen in the wound, which weakens the immune defense. Keeping the patient warm is linked to fewer surgical site infections.

答案

D · Low body temperature reduces blood flow and immune function in the wound
2.感染控制与患者安全

答案: A · 将该无菌区视为已污染,重新铺设

为什么是这个答案

用非无菌的手臂或物品越过无菌区,即使没有接触也会造成污染。应更换无菌区,非无菌物品应从无菌区旁边传递,而不是从上方越过。无菌状态存疑时,应视为已污染。

答案

A · 将该无菌区视为已污染,重新铺设
3.护理学基础

答案: C · No more than 10 seconds

为什么是这个答案

Rescuers look, listen and feel for normal breathing for no more than 10 seconds. If breathing is absent or not normal, they call for help and start CPR.

答案

C · No more than 10 seconds
4.护理学基础

答案: C · Protect the head, move objects away, time it and do not restrain

为什么是这个答案

During a seizure the nurse keeps the patient safe, notes the time and the features, and never puts anything in the mouth. Afterwards the patient is placed in the recovery position and the airway checked.

答案

C · Protect the head, move objects away, time it and do not restrain
5.微生物学

答案: D · Pseudomonas aeruginosa

为什么是这个答案

铜绿假单胞菌(Pseudomonas aeruginosa)是烧伤、机械通气患者和囊性纤维化患者肺部的机会性病原体。它对许多抗生素天然耐药。

答案

D · Pseudomonas aeruginosa
6.微生物学

答案: B · Staphylococcus

为什么是这个答案

葡萄球菌呈葡萄串状成簇生长;链球菌和肠球菌呈链状或成对。奈瑟菌是革兰氏阴性双球菌。

答案

B · Staphylococcus
