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: C · Assess the lungs, oxygen saturation and swelling, then inform the provider

为什么是这个答案

A rapid weight gain with orthopnea suggests fluid overload and worsening heart failure. The nurse assesses breathing and fluid status and informs the provider, who may adjust the diuretic.

答案

C · Assess the lungs, oxygen saturation and swelling, then inform the provider
2.优先排序与委派

答案: A · 当助理对该任务不熟悉或患者不太稳定时

为什么是这个答案

当被委派者经验较少、患者病情较难预测或任务风险较高时,需要更多的监督。被动的或班次结束时才检查,可能在还能纠正的时候错过问题。

答案

A · 当助理对该任务不熟悉或患者不太稳定时
3.感染控制与患者安全

答案: C · 被感染伤口渗液浸湿的敷料

为什么是这个答案

被血液或感染性体液污染的物品应依当地规定放入医疗废物。干净的包装放入一般废物或可回收垃圾,使医疗废物量尽可能少。

答案

C · 被感染伤口渗液浸湿的敷料
4.感染控制与患者安全

答案: D · Stop the infusion and check the patient’s blood glucose

为什么是这个答案

A concentration error means the dose delivered was wrong. The nurse stops the infusion, assesses the patient including blood glucose, treats as needed, notifies the prescriber and reports the event.

答案

D · Stop the infusion and check the patient’s blood glucose
5.实验室检查值与电解质

答案: C · The disease is unlikely, so it helps rule it out

为什么是这个答案

Sensitivity is the proportion of people with the disease who test positive. A highly sensitive test has few false negatives, so a negative result helps rule the disease out (the D-dimer is an example). Specificity relates to ruling in.

答案

C · The disease is unlikely, so it helps rule it out
6.实验室检查值与电解质

答案: A · "Dried apricots and raisins will be a good snack for me now"

为什么是这个答案

Dried fruits such as apricots and raisins are very high in potassium and should be limited in kidney disease with hyperkalemia. Limiting high-potassium foods, leaching vegetables and reading labels are correct strategies.核对依据: Potassium in diet · MedlinePlus (NIH) (2026); Spironolactone · MedlinePlus (NIH) (2018)

答案

A · "Dried apricots and raisins will be a good snack for me now"
7.临床护理

答案: D · 腹膜炎

为什么是这个答案

腹膜炎(常由穿孔引起)会导致肌紧张、腹壁强直以及活动时疼痛加重。这是外科急症。

答案

D · 腹膜炎
8.临床护理

答案: C · Ascending cholangitis

为什么是这个答案

Fever, jaundice and right upper quadrant pain (Charcot's triad) suggest infection of an obstructed bile duct. It can rapidly cause sepsis and needs antibiotics and biliary drainage.

答案

C · Ascending cholangitis
9.内外科护理:心血管与呼吸

答案: C · Supervised walking until pain is near maximal, then rest and repeat

为什么是这个答案

Supervised exercise programmes, walking to near-maximal claudication pain, resting and repeating for about 30 minutes several times a week, improve walking distance. With smoking cessation, an antiplatelet and a statin, this is first-line management.

答案

C · Supervised walking until pain is near maximal, then rest and repeat
10.内外科护理:心血管与呼吸

答案: B · A catheter-related deep vein thrombosis

为什么是这个答案

Upper-limb DVT is a recognised complication of PICCs and other central lines. Arm swelling, pain and distended veins should be reported, and an ultrasound arranged. The line is not flushed forcefully, and treatment usually involves anticoagulation.

答案

B · A catheter-related deep vein thrombosis
11.内外科护理:神经、内分泌与肾脏

答案: D · 低钠高钾

为什么是这个答案

醛固酮缺乏导致失钠、钾潴留,引起低钠血症和高钾血症。皮质醇缺乏还会加上低血糖和低血压。

答案

D · 低钠高钾
12.内外科护理:神经、内分泌与肾脏

答案: B · "I will put something between his teeth so he does not bite his tongue."

为什么是这个答案

Nothing should ever be put between the teeth during a seizure. Buccal midazolam is given between the gum and cheek, so the mouth does not need to be forced open. Timing the seizure and following the emergency care plan are correct.

答案

B · "I will put something between his teeth so he does not bite his tongue."
13.内外科护理:消化、围手术期与肿瘤

答案: A · Gas used during surgery irritating the diaphragm

为什么是这个答案

Carbon dioxide used to inflate the abdomen irritates the diaphragm, causing referred shoulder-tip pain. It usually settles within a few days; walking and simple analgesia help.

答案

A · Gas used during surgery irritating the diaphragm
14.内外科护理:消化、围手术期与肿瘤

答案: B · Use long-handled forceps to put it in the lead container; report it

为什么是这个答案

A dislodged source is picked up with long-handled forceps and placed in the shielded container kept in the room. The radiation safety officer and team are informed, following local policy.

答案

B · Use long-handled forceps to put it in the lead container; report it
