1公式与方法

优先排序与委派

方法

  1. 问自己:如果什么都不做,什么会最快伤害患者。
  2. 应用 ABC(心脏骤停时为 C-A-B),然后是 Maslow 需求层次:生理需要先于安全,安全先于心理需要。
  3. 比较各选项:急性先于慢性,不稳定先于稳定,意外先于预期,全身性先于局部,并将每项发现与患者的基线对照。
  4. 除非是紧急情况,否则先评估再行动;然后选择其他步骤所依赖的那一步。
  5. 委派时核对五项正确:任务、情境、人员、指示和监督。评估、宣教和评价仍由注册护士负责。

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。

实验室检查值与电解质

方法

  1. 把数值与本实验室自己的参考范围比较,再与患者的基线和趋势比较。
  2. 检查标本:溶血、延迟,或在静脉输液附近采血都可能得出错误结果。
  3. 把数值与其典型体征以及引起它的药物和疾病联系起来。
  4. 注意相互作用:低钾或低镁会增加地高辛中毒的风险;脱水会使锂浓度升高。
  5. 对患者采取行动:评估,血药浓度不安全时暂停用药,复述危急值并通知开医嘱的医生。

内外科护理:心血管与呼吸

方法

  1. 说出问题所在:泵衰竭、动脉阻塞、节律、血栓、气道狭窄、感染或设备问题。
  2. 先检查危险征象:低氧、低血压、胸痛、新出现的意识模糊、冰冷无脉搏的肢体。
  3. 让氧疗与患者相匹配:大多数人为 94–98%,有 CO₂ 潴留风险者为 88–92%。
  4. 把每种药物与其检测和风险联系起来:华法林与 INR,肝素与 aPTT 和血小板,利尿剂与血钾。
  5. 选择安全的第一步措施,然后升级处理并重新评估。

内外科护理:神经、内分泌与肾脏

方法

  1. 对每位新出现意识模糊、乏力或癫痫发作的患者都检查血糖。
  2. 把意识水平作为脑部问题最早的警示;瞳孔变化和库欣三联征出现得较晚。
  3. 对于糖尿病急症,要区分 DKA(酮体、酸中毒)和 HHS(渗透压很高、脱水);先补液。
  4. 对于钠和水,要判断是 ADH 过多(SIADH)还是缺乏(尿崩症),并缓慢纠正慢性变化。
  5. 对于肾脏问题,把原因分为肾前性、肾性或肾后性,并监测血钾和液体。

内外科护理:消化、围手术期与肿瘤

方法

  1. 想一想可能隐藏着什么:内出血、无发热的感染、SpO₂ 正常背后的通气不足。
  2. 利用术后的时间来缩小并发症的范围:出血在数小时内,胸部问题在数天内,伤口和吻合口漏出现得更晚。
  3. 对于疼痛,要评估、用多模式镇痛治疗、重新评估,并且在每次使用阿片类药物时监测镇静程度。
  4. 对于癌症患者,把低谷期的任何疾病都当作中性粒细胞减少性脓毒症处理,并了解肿瘤急症。
  5. 对于烧伤,只计算浅二度/深二度和三度的面积,从烧伤的时刻开始计算 Parkland 时间,并根据尿量调整。

3溶液

1.优先排序与委派

答案: D · 一名说“我喘不上气”的患者

为什么是这个答案

新出现的呼吸困难可能威胁生命,需要首先评估。维持液体袋输完、中度疼痛和一个问题可以随后处理。

答案

D · 一名说“我喘不上气”的患者
2.优先排序与委派

答案: C · Not witness the consent and inform the surgeon

为什么是这个答案

Valid consent requires a patient who can understand and decide. After a sedative this may not be possible, so the nurse does not witness it and informs the surgeon, who is responsible for obtaining consent.

答案

C · Not witness the consent and inform the surgeon
3.感染控制与患者安全

答案: D · Use the oral syringe or dosing cup that comes with the medicine

为什么是这个答案

Household spoons vary widely in size and cause dosing errors. A marked oral syringe or dosing device in mL gives an accurate dose.

答案

D · Use the oral syringe or dosing cup that comes with the medicine
4.感染控制与患者安全

答案: C · 评估患者并监测药物的影响

为什么是这个答案

首要任务是患者安全:评估、监测并通知开医嘱者,由其决定是否治疗。随后通过医院的系统上报差错,并按规定告知患者。

答案

C · 评估患者并监测药物的影响
5.实验室检查值与电解质

答案: B · Take it with food and a full glass of water, and do not crush extended-release tablets

为什么是这个答案

Oral potassium can irritate the esophagus and stomach, so it is taken with food and plenty of fluid, and extended-release forms are swallowed whole. Most salt substitutes contain potassium chloride and can add to the risk of hyperkalemia.核对依据: Potassium (drug information) · MedlinePlus (NIH) (2024)

答案

B · Take it with food and a full glass of water, and do not crush extended-release tablets
6.实验室检查值与电解质

答案: A · "I'll take my iron tablet with a big glass of milk"

为什么是这个答案

Calcium in milk, as well as antacids and tea, reduces iron absorption, so iron should not be taken with them. Vitamin C improves absorption, dark stools are expected, and iron overdose is a serious poisoning risk in young children.核对依据: Iron deficiency anemia - Medical Encyclopedia · MedlinePlus (NIH) (2025); Iron in diet - Medical Encyclopedia · MedlinePlus (NIH) (2025)

答案

A · "I'll take my iron tablet with a big glass of milk"
7.临床护理

答案: D · To reduce the risk of aspirating stomach contents

为什么是这个答案

Under general anaesthesia the airway reflexes are lost, so food or fluid in the stomach could be regurgitated and inhaled. Fasting reduces the risk of aspiration pneumonitis.

答案

D · To reduce the risk of aspirating stomach contents
8.临床护理

答案: A · 体液丢失引起的低血容量性休克

为什么是这个答案

大面积烧伤使液体移出循环,因此按公式指导的静脉液体复苏和尿量监测是关键。呼吸道烧伤是另一个早期危险。

答案

A · 体液丢失引起的低血容量性休克
9.内外科护理:心血管与呼吸

答案: C · 注射到腹部,保留气泡,注射后不揉按

为什么是这个答案

预充式低分子量肝素注射器内含有气泡,通常保留气泡以保证给予完整剂量。注射到腹部(远离脐部)的皮肤皱褶处、轮换注射部位、注射后不揉按,可减少瘀斑和血肿。

答案

C · 注射到腹部,保留气泡,注射后不揉按
10.内外科护理:心血管与呼吸

答案: D · A flail chest from ribs broken in more than one place

为什么是这个答案

A flail segment occurs when adjacent ribs are fractured in two or more places, so the segment moves paradoxically. It is often associated with lung contusion and respiratory failure. Management includes oxygen, strong analgesia and sometimes ventilation or surgical fixation.

答案

D · A flail chest from ribs broken in more than one place
11.内外科护理:神经、内分泌与肾脏

答案: D · Less urine, a rising creatinine and a tender graft

为什么是这个答案

Acute rejection may cause falling urine output, rising creatinine, weight gain, fever, and pain or tenderness over the graft. Many episodes are found on blood tests before symptoms appear, so regular monitoring is essential.

答案

D · Less urine, a rising creatinine and a tender graft
12.内外科护理:神经、内分泌与肾脏

答案: A · A patient with hyperthyroidism who is confused, with a temperature of 39.5 °C (103.1 °F)

为什么是这个答案

Fever and confusion in a patient with hyperthyroidism suggest thyroid storm, which can be fatal without urgent treatment. The other problems are expected or non-urgent.

答案

A · A patient with hyperthyroidism who is confused, with a temperature of 39.5 °C (103.1 °F)
13.内外科护理:消化、围手术期与肿瘤

答案: D · The nurse's assessment of what the problem is

为什么是这个答案

SBAR is Situation, Background, Assessment and Recommendation. Under Assessment, the nurse gives the findings and their interpretation, for example "I think the patient may be bleeding".

答案

D · The nurse's assessment of what the problem is
14.内外科护理:消化、围手术期与肿瘤

答案: A · Use an observational pain tool, give analgesia and reassess

为什么是这个答案

In dementia, pain often appears as agitation or guarding. An observational tool supports assessment; analgesia is given and effect reassessed. The hip is also assessed for injury such as a fracture.

答案

A · Use an observational pain tool, give analgesia and reassess
