感染控制与患者安全
方法
- 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。
- 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)。
- 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。
- 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。
- 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。

A nurse’s hands are dry and cracked from frequent hand hygiene. What is the best approach?
An audit shows poor hand hygiene compliance on a ward. Which plan is most likely to improve it?
Teaching a patient how to inject insulin mainly involves which domain of learning?
During a sterile dressing change, the nurse's sterile glove touches the bed rail. What should the nurse do?
什么是内毒素?
为什么在感染后的最初几周 HIV 抗体检测可能呈阴性?
答案: C · Use the hand lotion approved by the facility to keep the skin intact
Cracked skin is harder to clean and harbors more organisms. Facility-approved lotions help keep the skin healthy without reducing the effect of hand antiseptics such as chlorhexidine.
答案: C · A combined approach with education, hand rub at every bedside, regular audits and feedback
Multimodal strategies, such as easy access to hand rub at the point of care, training, reminders, audits with feedback and leadership support, improve hand hygiene more than single actions.
答案: A · Psychomotor
The psychomotor domain covers physical skills, the cognitive domain covers knowledge and the affective domain covers attitudes and feelings. Skills are learned by demonstration and practice.
答案: B · Remove the gloves, perform hand hygiene and put on new sterile gloves
A sterile glove that touches a non-sterile surface is contaminated and must be replaced. Cleaning it or covering it does not restore sterility.
答案: B · 革兰氏阴性菌外膜中的脂多糖
内毒素是脂多糖中的类脂 A。它引发伴有发热的强烈免疫反应,大量时可导致感染性休克。
答案: D · 机体尚未产生足以检测到的抗体
抗体需要数周才会出现。同时检测 p24 抗原的联合检测或病毒 RNA 检测可以缩短这一窗口期。
