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。

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。

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。

产科护理

方法

  1. 把产妇放在时间轴上定位:孕周、产程阶段或产后第几天,再判断此时什么是正常的。
  2. 找出处于危险中的对象:母亲、胎儿或新生儿,或者其中不止一个。
  3. 把发现与其原因联系起来:减速用 VEAL CHOP,出血用四个 T,产后用 BUBBLE-HE。
  4. 优先选择改善血流和氧合的措施(侧卧、停用缩宫素、宫底按摩),然后再升级处理。

儿科护理

方法

  1. 先记下患儿的年龄:它决定正常生命体征、发育里程碑和合适的疼痛量表。
  2. 评估气道、呼吸和循环,记住儿童代偿很久之后会迅速恶化。
  3. 让措施与发育阶段相匹配,并让家属参与。
  4. 检查答案对儿童是否安全:按体重计算,病毒感染不用阿司匹林,12 岁以下不用可待因。

精神科护理

方法

  1. 判断是否存在即时风险:自杀、暴力、药物急症或躯体疾病。
  2. 先保障安全:观察、移除危险物品、缓和局面、停用有害药物、寻求帮助。
  3. 选择治疗性回应:承认感受、陈述现实,避免虚假的安慰和“为什么”式提问。
  4. 尊重权利:采用限制最少的方案,知情同意,以及保密及其限度。

3溶液

1.护理学基础

答案: B · Stomach irritation and bleeding

为什么是这个答案

NSAIDs can irritate the stomach lining and cause ulcers and bleeding. They are taken with food, avoided in some patients and may also affect the kidneys.

答案

B · Stomach irritation and bleeding
2.护理学基础

答案: A · Late doses can cause severe stiffness, falls and swallowing problems

为什么是这个答案

Levodopa wears off quickly, and delays can cause rigidity, falls, swallowing difficulty and aspiration. It is a time-critical medicine in hospital.

答案

A · Late doses can cause severe stiffness, falls and swallowing problems
3.感染控制与患者安全

答案: C · When it is damp, loose or visibly soiled

为什么是这个答案

A dressing that is wet, loose or dirty no longer protects the insertion site and is changed using aseptic technique. Otherwise, it is changed according to policy.

答案

C · When it is damp, loose or visibly soiled
4.感染控制与患者安全

答案: A · Stop the infusion

为什么是这个答案

These are signs of anaphylaxis. The nurse stops the infusion at once, calls for help and supports the airway, and intramuscular epinephrine (adrenaline) is the first-line treatment. Documentation comes later.

答案

A · Stop the infusion
5.优先排序与委派

答案: A · With the palms of the hands, not the fingertips

为什么是这个答案

A wet plaster cast can be dented by fingertips, causing pressure points under the cast. It is handled with the palms, supported on pillows and left uncovered to dry.

答案

A · With the palms of the hands, not the fingertips
6.优先排序与委派

答案: A · Restlessness and a rising heart rate while the blood pressure is still normal

为什么是这个答案

In early shock, the body keeps the blood pressure up by raising the heart rate and narrowing vessels, so restlessness and tachycardia appear first. A falling blood pressure is a later sign.

答案

A · Restlessness and a rising heart rate while the blood pressure is still normal
7.临床护理

答案: B · Delays can quickly worsen rigidity, immobility and swallowing

为什么是这个答案

Levodopa has a short effect, so missed or late doses can lead to severe stiffness, falls, swallowing problems and, rarely, a dangerous hyperpyrexia-like state. Parkinson's medicines are treated as time-critical.

答案

B · Delays can quickly worsen rigidity, immobility and swallowing
8.临床护理

答案: A · 危及生命的哮喘,即将发生呼吸停止

为什么是这个答案

沉默肺、精疲力竭、发绀和意识混乱都是危及生命的征象。患者需要上级医生和危重症团队立即介入。

答案

A · 危及生命的哮喘,即将发生呼吸停止
9.实验室检查值与电解质

答案: C · 肌肉无力和腿部抽筋

为什么是这个答案

低钾引起肌肉无力、抽筋、肠蠕动减弱(便秘,甚至肠麻痹)和心律失常。T 波高尖见于高钾血症,口周麻刺感提示低钙。核对依据: Heart failure - fluids and diuretics · MedlinePlus (NIH); Low blood potassium · MedlinePlus (NIH) (2025)

答案

C · 肌肉无力和腿部抽筋
10.实验室检查值与电解质

答案: C · 28 mEq/L, a high anion gap

为什么是这个答案

The anion gap is 140 − (100 + 12) = 28 mEq/L; a typical normal value is about 8–12 mEq/L when potassium is not included. A high anion gap metabolic acidosis suggests unmeasured acids, for example ketones in DKA or lactate in shock.核对依据: Anion Gap Blood Test · MedlinePlus (NIH) (2024)

答案

C · 28 mEq/L, a high anion gap
11.药理学

答案: B · Better alertness and orientation, with two to three soft stools a day

为什么是这个答案

Lactulose is adjusted to give about two to three soft stools a day and to lower ammonia, improving mental status. Excessive diarrhoea can cause dehydration and electrolyte loss.

答案

B · Better alertness and orientation, with two to three soft stools a day
12.药理学

答案: C · 甲状腺功能异常和肺纤维化

为什么是这个答案

胺碘酮富含碘并在组织中蓄积,可引起甲状腺功能减退或亢进、肺纤维化、肝损伤、光敏感和角膜沉积。其他几对分别符合氨基糖苷类、苯妥英和 ACE 抑制剂。

答案

C · 甲状腺功能异常和肺纤维化
13.内外科护理:心血管与呼吸

答案: C · When the gag and cough reflexes have returned

为什么是这个答案

Local anaesthetic sprayed on the throat abolishes the gag and cough reflexes for a time, so food or fluid could be aspirated. The nurse checks that the reflexes have returned (often after about one to two hours) before giving sips of water and then food.

答案

C · When the gag and cough reflexes have returned
14.内外科护理:心血管与呼吸

答案: C · Use another reliable method, as rifampicin reduces the pill's effect

为什么是这个答案

Rifampicin induces liver enzymes that break down oestrogen and progestogen, so hormonal contraception may fail. A non-hormonal or unaffected method, such as a copper IUD, is advised during and for a time after treatment. The interaction also affects warfarin and many other drugs.

答案

C · Use another reliable method, as rifampicin reduces the pill's effect
15.内外科护理:神经、内分泌与肾脏

答案: B · 频繁的神经系统检查和血压

为什么是这个答案

溶栓后应频繁进行神经系统观察、血压测量和出血检查。新出现的头痛、呕吐、GCS 下降或血压升高可能提示出血。通常 24 小时内避免使用抗血小板药和抗凝药。

答案

B · 频繁的神经系统检查和血压
16.内外科护理:神经、内分泌与肾脏

答案: C · Autonomic dysfunction, which needs continuous cardiac monitoring

为什么是这个答案

Guillain–Barré syndrome can involve autonomic nerves, causing labile blood pressure and dangerous arrhythmias. Patients need continuous ECG monitoring and close observation, often in a high-dependency setting.

答案

C · Autonomic dysfunction, which needs continuous cardiac monitoring
17.内外科护理:消化、围手术期与肿瘤

答案: A · Alternate staples first, then the rest if the wound holds

为什么是这个答案

Removing alternate staples first allows the nurse to check that the wound edges stay together. If the wound is secure, the rest are removed, and adhesive strips can be applied for support.

答案

A · Alternate staples first, then the rest if the wound holds
18.内外科护理:消化、围手术期与肿瘤

答案: B · Keep the head of the bed at or below 30° if possible; use slide sheets

为什么是这个答案

A high head position makes patients slide, causing shear on the sacrum. A lower head position when clinically possible, knee break or foot support, and slide sheets for moving reduce shear and friction.

答案

B · Keep the head of the bed at or below 30° if possible; use slide sheets
19.产科护理

答案: D · Harmless dermal melanocytosis, to be documented

为什么是这个答案

Congenital dermal melanocytosis (Mongolian spots) are harmless and usually fade over years. They should be documented clearly so they are not mistaken later for bruises.

答案

D · Harmless dermal melanocytosis, to be documented
20.产科护理

答案: A · Check whether the head is visible and stay with her

为什么是这个答案

A strong urge to push and rectal pressure suggest full dilation or imminent birth. The nurse stays, checks for crowning, calls for help and prepares for birth. Opioids close to birth can depress the newborn's breathing.

答案

A · Check whether the head is visible and stay with her
21.儿科护理

答案: C · Preventing dehydration

为什么是这个答案

Hand, foot and mouth disease, usually caused by coxsackievirus, is self-limiting. The main risk is dehydration from painful mouth ulcers, so cool fluids, soft foods and analgesia are given and wet nappies are monitored.

答案

C · Preventing dehydration
22.儿科护理

答案: D · Keep them apart, not sharing rooms, equipment or play areas

为什么是这个答案

People with CF can pass bacteria such as Pseudomonas aeruginosa and Burkholderia cepacia to each other, worsening lung disease. Children with CF are kept apart in hospital and clinics, and equipment is not shared.

答案

D · Keep them apart, not sharing rooms, equipment or play areas
23.精神科护理

答案: A · It uses magnetic pulses on the scalp while the patient is awake, without causing a seizure

为什么是这个答案

rTMS stimulates specific brain areas with a magnetic coil held on the head. It does not need anaesthesia or cause a seizure and is used for depression that has not responded to medicines.

答案

A · It uses magnetic pulses on the scalp while the patient is awake, without causing a seizure
24.精神科护理

答案: A · Neither confirm nor deny that he is there, and offer to pass on a message

为什么是这个答案

Without the patient's consent, the nurse should not disclose that a person is receiving mental health care. Offering to pass on a message respects confidentiality while allowing the patient to decide.

答案

A · Neither confirm nor deny that he is there, and offer to pass on a message
25.护理数学与单位换算

答案: x = 93 kg

取整:看舍入位后面的那个数字:5 或更大则进位,4 或更小则保持原数字不变。只对最终答案取整,绝不对中间步骤取整。典型的考试规则:1 mL 或以上的体积取到十分位,低于 1 mL 的体积取到百分位,滴速取整到整滴,体重取到一位小数;务必遵循题目所规定的规则。

十分位位上的数字

92.9715 → 9

只看下一位数字

92.9715 → 7
7 大于或等于 5,所以 9 进一。
后面的数字(15)不考虑:只取整一次,不要逐位取整。

取整

x = 93 kg

答案

x = 93 kg
26.护理数学与单位换算

答案: V = 420 mL

量纲分析:先写出已知量,再乘以写成分数形式的换算系数(例如 60 min/1 h 或 1 mg/1000 mcg),使每个不需要的单位在分子和分母各出现一次并相互约去。只剩下所求单位时再计算。使用题目给出的等量关系,只对最终答案取整。

每次剂量的体积

½ tbsp = 0.5·15 = 7.5 mL

整个疗程

V = 7.5 mL × 4/天 × 14 = 420 mL

答案

V = 420 mL
27.剂量计算

答案: V = 9 mL

抽取剂量:体积 = (处方剂量/药物浓度) × 药物体积。先换算成相同的单位,再检查该体积是否适合注射器,并落在它的某一个刻度上。

按体重计算剂量

D = 15·12 = 180 mg

体积

V = 180/20 = 9 mL

在注射器上

在这支 10 mL 的注射器上,每条小刻度线代表 0.2 mL。

答案

V = 9 mL
28.剂量计算

答案: V = 0.93 mL

抽取剂量:体积 = (处方剂量/药物浓度) × 药物体积。先换算成相同的单位,再检查该体积是否适合注射器,并落在它的某一个刻度上。

单位相同

0.5 mg/mL = 500 mcg/mL

体积

V = 465/500 = 0.93 mL

答案

V = 0.93 mL
29.静脉输液速度

答案: R = 25 gtt/min

输注速率:输液泵按 mL/h = 体积/时间(小时)设定。重力滴注按每分钟滴数计:gtt/min = 体积 (mL) × 滴系数 (gtt/mL)/时间 (min)。 滴系数印在输液器包装上:普通输液器为 10、15 或 20 gtt/mL(输血器在美国常为 10 gtt/mL,在英国为 15),微量输液器为 60 gtt/mL。务必使用题目或包装给出的滴系数。

以分钟计的时间

10·60 = 600 min

滴速

R = 250·60/600 = 25 gtt/min

答案

R = 25 gtt/min
30.静脉输液速度

答案: D = 10 mg/h

输注速率:输液泵按 mL/h = 体积/时间(小时)设定。重力滴注按每分钟滴数计:gtt/min = 体积 (mL) × 滴系数 (gtt/mL)/时间 (min)。 滴系数印在输液器包装上:普通输液器为 10、15 或 20 gtt/mL(输血器在美国常为 10 gtt/mL,在英国为 15),微量输液器为 60 gtt/mL。务必使用题目或包装给出的滴系数。

浓度

250/250 = 1 mg/mL

给药速率

D = 1·10 = 10 mg/h

答案

D = 10 mg/h
31.静脉输液与液体平衡

答案: I = 1280 mL

出入量:入量计入所有进入体内的液体(口服液体、静脉输液、静脉用药及冲管液、管饲);冰屑按其体积的一半计。出量计入尿液、引流液、呕吐物和其他丢失。平衡 = 总入量 − 总出量;平衡为负表示净丢失。 这些数字仅供练习;在临床工作中务必遵循当地规程,高危剂量须经双人核对。

计算入量

口服: 100 + 240 = 340 mL
冰屑: 200/2 = 100 mL
静脉输液: 80·8 = 640 mL
静脉抗生素: 2·100 = 200 mL
I = 1280 mL

答案

I = 1280 mL
32.静脉输液与液体平衡

答案: V = 140 mL

输液时间:时间 (h) = 待输体积 (mL)/速率 (mL/h);使用袋中剩余的体积,而不是袋的容量。已输入体积 = 速率 × 时间。把小数小时换算为小时和分钟时,用小数部分 × 60(0.5 h = 30 min,而不是 50 min)。 这些数字仅供练习;在临床工作中务必遵循当地规程,高危剂量须经双人核对。

经过的时间

08:15 → 11:15 = 3 h

已输入体积

120·3 = 360 mL

剩余体积

V = 500 − 360 = 140 mL

答案

V = 140 mL
