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 · Day 1 after bowel surgery, new chest pain and heart rate 110/min

为什么是这个答案

New chest pain and tachycardia after surgery could be a myocardial infarction or pulmonary embolism. This patient needs immediate assessment; the others have routine needs.

答案

D · Day 1 after bowel surgery, new chest pain and heart rate 110/min
2.优先排序与委派

答案: B · “Check his glucose and give the insulin according to the sliding scale.”

为什么是这个答案

Giving insulin is medication administration and needs a licensed nurse. Measuring glucose, hygiene and supervised walking are suitable tasks with clear reporting instructions.

答案

B · “Check his glucose and give the insulin according to the sliding scale.”
3.感染控制与患者安全

答案: D · Hold it away from the uniform and place it straight into a linen bag

为什么是这个答案

Soiled linen is rolled up, held away from the uniform and placed directly into a laundry bag at the bedside. Shaking linen spreads organisms into the air, and the floor is a contaminated surface.

答案

D · Hold it away from the uniform and place it straight into a linen bag
4.感染控制与患者安全

答案: D · An acute bacterial infection

为什么是这个答案

In acute bacterial infection, the bone marrow releases neutrophils before they mature, raising the proportion of bands. Allergies and parasites raise eosinophils, and viral infections more often raise lymphocytes.

答案

D · An acute bacterial infection
5.实验室检查值与电解质

答案: A · Creatine kinase (CK)

为什么是这个答案

Statins can cause myopathy and, rarely, rhabdomyolysis. A raised CK confirms muscle injury, and the provider may stop the statin. The nurse also asks about dark urine, which can signal myoglobin in the urine.核对依据: Creatine Kinase · MedlinePlus (NIH) (2023)

答案

A · Creatine kinase (CK)
6.实验室检查值与电解质

答案: A · "I'll take aspirin if I get a headache"

为什么是这个答案

Aspirin irreversibly inhibits platelet function and raises the bleeding risk further in thrombocytopenia, so it and other NSAIDs are avoided unless prescribed. An electric razor, gentle nose blowing and a soft toothbrush reduce minor bleeding.核对依据: Bleeding and Bruising (Thrombocytopenia) and Cancer Treatment · National Cancer Institute (NIH) (2022); Aspirin · MedlinePlus (NIH) (2025)

答案

A · "I'll take aspirin if I get a headache"
7.临床护理

答案: A · 哮喘

为什么是这个答案

非选择性甚至心脏选择性 β 受体阻滞剂都可能引起支气管痉挛,因此哮喘患者通常应避免使用。

答案

A · 哮喘
8.临床护理

答案: B · "I will rub the area firmly after the injection."

为什么是这个答案

Rubbing the site after an anticoagulant injection increases bruising and is avoided. Rotating sites, injecting subcutaneously and reporting bleeding are correct.

答案

B · "I will rub the area firmly after the injection."
9.内外科护理:心血管与呼吸

答案: D · 站起来之前先在床边坐一会儿

为什么是这个答案

开始降压治疗时,体位性(直立性)低血压很常见。缓慢改变体位可降低跌倒风险。持续存在症状时应报告,以便测量卧位和立位血压并复核剂量。

答案

D · 站起来之前先在床边坐一会儿
10.内外科护理:心血管与呼吸

答案: B · Stop smoking, control BP and seek help at once for sudden back pain

为什么是这个答案

Small aneurysms are usually monitored with regular ultrasound, with repair considered when they reach a threshold size or grow fast. Stopping smoking slows growth, and BP and cardiovascular risk are managed. Sudden abdominal or back pain may mean rupture and needs emergency care.

答案

B · Stop smoking, control BP and seek help at once for sudden back pain
11.内外科护理:神经、内分泌与肾脏

答案: D · The suppressed adrenal glands cannot make enough cortisol at once

为什么是这个答案

Long-term glucocorticoids suppress ACTH, and the adrenal glands shrink. Stopping abruptly can cause adrenal insufficiency or crisis. Doses are reduced gradually so the glands can recover.

答案

D · The suppressed adrenal glands cannot make enough cortisol at once
12.内外科护理:神经、内分泌与肾脏

答案: B · The INR, because it may rise

为什么是这个答案

As thyroid function returns to normal, clotting factors are broken down faster, which increases the effect of warfarin. The INR is checked more often and the warfarin dose may need to be reduced.

答案

B · The INR, because it may rise
13.内外科护理:消化、围手术期与肿瘤

答案: B · Eat a normal, balanced diet and introduce foods gradually

为什么是这个答案

People with a colostomy can usually eat a normal diet. Foods are reintroduced gradually to see how each one affects gas, odour and output, and regular meals and fluids help.

答案

B · Eat a normal, balanced diet and introduce foods gradually
14.内外科护理:消化、围手术期与肿瘤

答案: C · Potassium 6.0 mmol/L

为什么是这个答案

Spironolactone blocks aldosterone and can cause hyperkalaemia, which risks arrhythmias. A potassium of 6.0 mmol/L is above the normal range (about 3.5–5.0) and needs urgent review before further doses.

答案

C · Potassium 6.0 mmol/L
