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: B · 4 级

为什么是这个答案

对稳定的患者,ESI 3 至 5 级取决于预期的资源:两种或更多为 3 级,一种为 4 级,没有为 5 级。简单缝合算一种资源,因此这是 4 级。

答案

B · 4 级
2.优先排序与委派

答案: C · “I will rub the area after the injection to help it absorb.”

为什么是这个答案

Rubbing the site after a low-molecular-weight heparin injection increases bruising. The abdomen away from the navel, rotating sites and reporting bleeding are correct.

答案

C · “I will rub the area after the injection to help it absorb.”
3.感染控制与患者安全

答案: C · That the portable cylinder has enough oxygen for the whole trip

为什么是这个答案

The nurse checks the cylinder gauge and makes sure there is enough oxygen for the trip and possible delays. The cylinder is secured in a holder on the chair, not on the patient’s lap.

答案

C · That the portable cylinder has enough oxygen for the whole trip
4.感染控制与患者安全

答案: D · “I can share towels with my family if I wash them every week.”

为什么是这个答案

MRSA spreads by direct contact and shared items, so towels, razors and linen should not be shared. Hand hygiene, covering the wound and bagging dressings are correct.

答案

D · “I can share towels with my family if I wash them every week.”
5.实验室检查值与电解质

答案: D · 稳定心肌细胞膜,但不降低钾

为什么是这个答案

钙可在数分钟内对抗高钾对心脏电活动的影响。钾仍必须通过转移入细胞(胰岛素加葡萄糖)和排出体外(结合剂、利尿剂或透析)来降低。核对依据: High potassium level · MedlinePlus (NIH) (2025)

答案

D · 稳定心肌细胞膜,但不降低钾
6.实验室检查值与电解质

答案: A · Report urgently for imaging and possible reversal

为什么是这个答案

A head injury in an anticoagulated patient, with worsening headache and drowsiness, suggests intracranial bleeding. The provider is told at once, neurological checks are done often, urgent imaging is arranged, and warfarin reversal (vitamin K and a prothrombin complex concentrate) may be prescribed.核对依据: Taking warfarin (Coumadin, Jantoven) - what to ask your doctor · MedlinePlus (NIH) (2025); Prothrombin Time Test and INR (PT/INR) · MedlinePlus (NIH) (2024)

答案

A · Report urgently for imaging and possible reversal
7.临床护理

答案: C · 地高辛中毒

为什么是这个答案

地高辛中毒会引起恶心、呕吐、心动过缓、心律失常和视觉障碍。低钾会增加风险。应暂停给药并报告。

答案

C · 地高辛中毒
8.临床护理

答案: D · Give another dose of fast-acting carbohydrate and recheck

为什么是这个答案

If blood glucose remains below the threshold (4 mmol/L in UK guidance, 70 mg/dL in US guidance), the fast-acting treatment is repeated. Once it is above the threshold, a longer-acting carbohydrate such as a sandwich or the next meal helps prevent recurrence.

答案

D · Give another dose of fast-acting carbohydrate and recheck
9.内外科护理:心血管与呼吸

答案: C · With all meals and snacks that contain fat

为什么是这个答案

In CF, thick secretions block the pancreatic ducts, causing fat malabsorption and fatty stools. Enzyme capsules are taken with every meal and fat-containing snack, with the dose adjusted to fat intake. Fat-soluble vitamins (A, D, E, K) are also supplemented.

答案

C · With all meals and snacks that contain fat
10.内外科护理:心血管与呼吸

答案: D · Measuring and recording the morning weight

为什么是这个答案

Weighing a stable patient is a routine, measurable task that can be delegated, with the result reported to the nurse. Assessment, patient teaching and clinical decisions about medicines require the registered nurse's judgement and cannot be delegated.

答案

D · Measuring and recording the morning weight
11.内外科护理:神经、内分泌与肾脏

答案: C · Use glasses and hearing aids and reorient the patient often

为什么是这个答案

Non-drug measures are the mainstay of delirium care: glasses and hearing aids, clocks and calendars, familiar faces, good sleep, hydration, mobility and treating the cause. Restraints and frequent moves make delirium worse.

答案

C · Use glasses and hearing aids and reorient the patient often
12.内外科护理:神经、内分泌与肾脏

答案: D · The kidneys clear less insulin, so it lasts longer

为什么是这个答案

The kidneys clear a large share of insulin. As kidney function falls, insulin stays in the blood longer and some oral agents build up, so hypos increase. Insulin doses often need to be reduced.

答案

D · The kidneys clear less insulin, so it lasts longer
13.内外科护理:消化、围手术期与肿瘤

答案: C · 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

C · 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: D · 上腔静脉阻塞

为什么是这个答案

肿瘤可压迫或侵犯上腔静脉,引起面部和手臂肿胀、胸壁静脉扩张、头痛和呼吸困难。应让患者坐起并紧急评估;治疗包括类固醇、支架置入以及放疗或化疗。

答案

D · 上腔静脉阻塞
