Prioritisation frameworks for exam questions: airway first, unstable before stable and delegation

Why prioritisation questions feel hard

In prioritisation questions, several options are reasonable and one is first. The wrong answers are not silly. They are things you would do soon. The exam is testing whether you can order them, and ordering depends on a small set of rules applied to the facts in the stem.

This is exam-preparation revision, not clinical guidance. In practice, follow your own organisation’s policies and current guidelines.

Framework 1: airway, breathing, circulation

Threats to life are managed in order: airway, then breathing, then circulation, then disability and exposure. A patient with a compromised airway comes before a patient with a high blood pressure, and a patient with new breathing difficulty comes before a patient with stable pain. The mnemonics post lists ABCDE.

One exception students should know: in cardiac arrest, current resuscitation guidelines for adults begin with chest compressions. Learn the guideline your exam follows.

Framework 2: unstable before stable, acute before chronic

A patient with sudden change is higher priority than a patient with a long-standing condition that is unchanged. New confusion, new chest pain, new weakness on one side, a sudden fall in blood pressure or a sudden drop in oxygen saturation outrank a stable, expected finding such as a chronic cough in a patient with known lung disease.

Look for the word “new” or “sudden”, and for trends. A blood pressure that has fallen over an hour matters more than a single low reading in someone who is always low.

Framework 3: assess before you intervene

When a patient has a problem and you do not yet know its cause, assessment usually comes before action. Check the pulse before giving a drug for palpitations. Look at the patient before you silence an alarm. The exception is when the stem says the patient is in immediate danger, in which case act.

Questions that ask for the “first” nursing action often reward gathering data, unless the patient is clearly in a crisis that needs a specific response.

Framework 4: physiological needs before the rest

Maslow’s hierarchy is often used in nursing education to rank needs: physiological needs such as oxygen, fluids and pain, then safety, then love and belonging, then esteem, then self-actualisation. If a question compares a physical need with an emotional one and both are real, the physical one usually comes first, unless the emotional state creates a safety risk, such as suicidal thoughts.

Worked example: who first?

Four patients need attention at the same time.

1. A man, day two after a hip replacement, asks for pain relief; his observations are stable.
2. A woman with known heart failure, who says she is more short of breath than usual and has a new cough with pink frothy sputum.
3. A man waiting for discharge teaching about his insulin.
4. A woman with a chronic leg ulcer whose dressing is due.
5. The second patient has a sudden change in breathing and a picture that may suggest acute pulmonary oedema, so she comes first. The first and the last two are stable, and their needs come after.

Delegation basics

Delegation questions test who may do what. In many nursing frameworks, assessment, care planning, patient teaching and evaluation stay with the registered nurse. Routine tasks for a stable patient, such as taking observations that are expected to be normal, assisting with hygiene or feeding a patient without swallowing problems, may be delegated to appropriately trained assistants. The “five rights of delegation” are often summarised as the right task, circumstance, person, direction and communication, and supervision and evaluation. If a patient is unstable or the task needs judgement, do not delegate. Check the rules in your own jurisdiction.

A second worked example: what first?

A nurse finds a patient who is post-operative day one after abdominal surgery. The patient is pale, sweaty and says they feel faint. The blood pressure is lower than earlier and the heart rate is higher. The options include giving pain relief, checking the wound dressing, recording a full set of observations and calling the surgical team, and encouraging fluids. Using the frameworks, the picture suggests possible haemorrhage or shock. Check airway and breathing, and look at circulation: which means getting urgent help and assessing for bleeding, rather than giving oral fluids or analgesia first. A reasonable first action is to stay with the patient, ensure airway and breathing, and escalate urgently using SBAR, while taking the observations and inspecting the site.

Exam answers will be written as single options. The one that recognises possible shock and escalates comes before comfort measures.

Pitfalls

Common traps include picking the action you would like to do rather than the one that is most urgent, ignoring the word “new” in the stem, delegating tasks that need judgement and forgetting that safety comes before comfort. Another is overthinking: if a patient has a life-threatening problem and one option addresses it directly, choose that option. If two options both address the threat, the one that takes less time or comes earlier in the sequence is usually first.

Practising prioritisation

Make a deck of ten patient vignettes of two sentences each. Shuffle and rank them, writing a one-line reason for each rank. Then compare with a colleague. The reasons matter more than the order. Use the question bank for timed sets of prioritisation questions, and put any rule you learn on your rules page. A good habit is to say aloud “what could kill this patient first?” before choosing.

When the rules collide

Sometimes two frameworks point in different directions. A patient with a chronic condition may have an urgent safety risk, or an anxious relative may be demanding attention while a quiet patient is getting worse. In these cases, return to the first principle: what threatens life or safety soonest? Use the most immediate threat to decide, then apply the other frameworks to order the rest. If a question seems to have no clear first step, look for the option that gathers information quickly without delay, or the option that protects the patient from immediate harm.

Remember too that the exam writes for a simplified world. Do not add facts that the stem does not give. Answer for the patient described, with the resources described.

A five-minute drill

Write four short vignettes on index cards, each with one key feature, such as a new confusion or a sudden drop in saturation. Shuffle them. Sort them by urgency and say your reason for each. Repeat with a different set each day for a week. This builds the habit of scanning for what has changed, which is the skill the exam rewards.

Triage systems

Emergency departments use structured triage scales, such as five-level systems that rank patients by urgency and resources needed, and disaster triage that uses colour categories. The exact scales vary between countries and hospitals, so learn the general principle: life-threatening problems first, then urgent, then less urgent. Practise with scenario questions in the question bank, and see the sepsis and SBAR posts for related skills.
