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。

  1. ALeave it running and place a towel over it until it dries
  2. BWipe it dry quickly with a towel and keep using it for the infusion
  3. CSwitch it off and unplug it safely, then have it checked before reuse
  4. DTurn the pump upside down to drain it while running
2.感染控制与患者安全困难

一名患者正在持续输注高警示药物。交接班时,哪种做法最安全?

  1. A交班护士在护士站说“泵没问题”
  2. B两名护士对照处方共同核对输注泵和药袋
  3. C只检查速率,不检查药物或浓度
  4. D接班护士在本班结束时检查
3.护理学基础中等

When washing a patient's eyes, how should each eye be wiped?

  1. AOnly the eye that looks dirty needs cleaning
  2. BIn small circles over the closed eyelid of both eyes
  3. CFrom the inner corner outwards, using a clean part of the cloth for each eye
  4. DFrom the outer corner inwards, using the same part of the cloth for both
4.护理学基础困难

A healthcare assistant (nursing assistant) has recorded a blood pressure of 82/50 mmHg during routine observations but did not report it. What should the registered nurse do first?

  1. ATalk to the healthcare assistant about reporting
  2. BRepeat the observations at the next routine time
  3. CComplete an incident report
  4. DAssess the patient straight away
5.微生物学中等

许多抗真菌药物以麦角固醇为靶点。为什么这样有效?

  1. A麦角固醇存在于真菌细胞膜中,而人体细胞中没有
  2. B人体细胞利用麦角固醇产生能量
  3. C麦角固醇是细菌细胞壁的主要结构成分
  4. D麦角固醇只存在于病毒中
6.微生物学困难

  4. D心脏和大脑受损

3溶液

1.感染控制与患者安全

答案: C · Switch it off and unplug it safely, then have it checked before reuse

为什么是这个答案

Liquid on electrical equipment can cause shock or failure. The device is turned off and unplugged without touching wet parts, the patient’s infusion is managed with another device, and the pump is checked by the biomedical team.

答案

C · Switch it off and unplug it safely, then have it checked before reuse
2.感染控制与患者安全

答案: B · 两名护士对照处方共同核对输注泵和药袋

为什么是这个答案

交接班时在床边核对,沿管路从药袋追溯到患者,并对照处方核对药物、浓度、剂量和速率,可及早发现编程错误。

答案

B · 两名护士对照处方共同核对输注泵和药袋
3.护理学基础

答案: C · From the inner corner outwards, using a clean part of the cloth for each eye

为什么是这个答案

Wiping from the inner to the outer canthus moves debris away from the tear duct. Using a clean part of the cloth for each eye prevents spreading infection between them.

答案

C · From the inner corner outwards, using a clean part of the cloth for each eye
4.护理学基础

答案: D · Assess the patient straight away

为什么是这个答案

A low blood pressure may mean deterioration, so the nurse assesses the patient at once and escalates if needed. Feedback to the assistant and reporting follow afterwards.

答案

D · Assess the patient straight away
5.微生物学

答案: A · 麦角固醇存在于真菌细胞膜中,而人体细胞中没有

为什么是这个答案

真菌细胞膜含有麦角固醇,而人体细胞膜含有胆固醇。唑类阻断麦角固醇的合成,两性霉素与麦角固醇结合,因此它们能选择性地作用于真菌。

答案

A · 麦角固醇存在于真菌细胞膜中,而人体细胞中没有
6.微生物学

答案: C · 感染部位的无痛性溃疡(硬下疳)

为什么是这个答案

梅毒螺旋体(Treponema pallidum)在一期引起无痛性硬下疳。二期出现皮疹和全身症状,三期梅毒可损害心脏和神经系统。疼痛性水疱提示疱疹。

答案

C · 感染部位的无痛性溃疡(硬下疳)
