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。

答案: C · Assess the lungs, oxygen saturation and swelling, then inform the provider
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: A · 当助理对该任务不熟悉或患者不太稳定时
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。

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: D · Stop the infusion and check the patient’s blood glucose
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: C · The disease is unlikely, so it helps rule it out
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: A · "Dried apricots and raisins will be a good snack for me now"

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: C · Supervised walking until pain is near maximal, then rest and repeat
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: B · A catheter-related deep vein thrombosis
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 · "I will put something between his teeth so he does not bite his tongue."
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: A · Gas used during surgery irritating the diaphragm
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.
