优先排序与委派
方法
- 问自己:如果什么都不做,什么会最快伤害患者。
- 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。
- 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。
- 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。
- 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。
公式表、每个专题的关键方法步骤和 14 道练习题,完整解答附在最后。
Which patient should the RN see first after receiving a report from the night nurse?
The charge nurse overhears four instructions from an RN to a nursing assistant. Which one needs to be corrected?
How should a nurse handle soiled bed linen?
A patient’s white cell differential shows a raised number of band (immature) neutrophils, called a “shift to the left”. What does this usually suggest?
A patient taking a statin reports new, unexplained muscle pain and weakness. Which laboratory test would the nurse expect to be ordered?
The nurse teaches a patient with thrombocytopenia (platelets 25 × 10³/µL) about home safety. Which statement shows a need for further teaching?
病房中一名患者在首剂 β 受体阻滞剂后出现喘鸣和气短。哪种病史最可能导致这种情况?
A patient is taught to self-inject low-molecular-weight heparin. Which statement shows a need for further teaching?
一名刚开始服用降压药的患者起床时感到头晕。正确的建议是什么?
A 70-year-old man has a small abdominal aortic aneurysm found on screening and is placed under surveillance. Which advice is most important?
Why should long-term steroid treatment not be stopped suddenly?
A patient on warfarin starts levothyroxine for hypothyroidism. What should the nurse expect to monitor more closely?
A patient with a new colostomy asks what to eat at home. Which advice is most appropriate?
A patient with cirrhosis takes spironolactone and furosemide. Which blood result should the nurse report before the next dose?
答案: D · Day 1 after bowel surgery, new chest pain and heart rate 110/min
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: B · “Check his glucose and give the insulin according to the sliding scale.”
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: D · Hold it away from the uniform and place it straight into a linen bag
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 · An acute bacterial infection
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: A · Creatine kinase (CK)
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 · "I'll take aspirin if I get a headache"
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 · 哮喘
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: B · "I will rub the area firmly after the injection."
Rubbing the site after an anticoagulant injection increases bruising and is avoided. Rotating sites, injecting subcutaneously and reporting bleeding are correct.
答案: D · 站起来之前先在床边坐一会儿
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: B · Stop smoking, control BP and seek help at once for sudden back pain
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: D · The suppressed adrenal glands cannot make enough cortisol at once
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: B · The INR, because it may rise
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 · Eat a normal, balanced diet and introduce foods gradually
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: C · Potassium 6.0 mmol/L
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.
